Good Repair, Bad Repair

2009-12-01T14:31:00.000-08:00

If you have an asphalt parking lot, and have had to maintain it for any amount of time, then you probably know what we’re talking about when it comes to repairs. Sooner or later (one hopes for later) you’re going to have to address issues with your asphalt surface in the form of patching. The need to patch can arise from any number of issues—the most common being water and puddling issues, alligator cracking, and potholes.

The way to repair these issues varies as well—from just removing the oldasphalt and filling the area in, to a full depth removal which involves excavating the area down to the sub-base and installing fresh courses of stone and asphalt. Each contractor has a different method of how to repair a damaged area—some good, some bad. Typically, though, a general repair for a damaged area in your asphalt surface would go something like this:

1) The contractor will mark out the extents of the damaged area with paint

2) The area will be sawcut and all damaged asphalt will be removed from that area.

3) New asphalt will be placed in the area and compacted.

Pretty simple, right? Well, to a certain extent it is; but then there are the intricacies of asphalt repairs which most people don’t get to see, and not all contractors adhere to. Yes, the bottom line of asphalt repairs is to get the broken asphalt out and put the new asphalt in, but to make it look good, to get it to last, there is much more that your paving contractor should be doing.

What is a good repair? A good repair is fundamentally 3 things:

1. Structurally sound

2. Aesthetically pleasing

3. Either improves or maintains existing drainage patterns.

A good repair starts with the contractor’s quote. A good quote will tell you what exactly the contractor plans to do, for example:

“Saw cut perimeter of repairs as necessary. Excavate repair areas to a depth of 4” and haul offsite. Re-compact stone base and tack edges of repair. Install 4” of S9.5B asphalt in (2) lifts. Roll to a smooth even finish.”

By clearly specifying their intent a contractor obligates himself to the results and makes it easier for you to compare their quote with another contractor’s. Another important factor to look for and compare is the quantity of repairs to be performed. Some contractors will not divulge the square footage or yardage of asphalt they are repairing. It is important to make sure you get quantities out of the contractors so you can make sure you get what you pay for. It usually makes sense to try to get the bidders quoting on a apples to apples basis, but sometimes that may not be necessary because you have more confidence in one contractor as opposed to the other contractor.

Good repair work is work that meets the above 3 requirements. The final product should be something which is aesthetically pleasing, structurally sound and addresses the drainage needs of the area.

There is one last thing you must consider however and it is probably more important than any other issue. Does the contractor stand behind their work and are they committed to building long term relationships? Even the best contractors make mistakes from time to time. That is going to happen. Your parking lot is not going away. The older it gets the more maintenance it will need. You’re not going to want to chase several quotes every time you need minor repairs done. A contractor that is committed to quality should also be committed to building long term customer relationships by being always fair with their pricing and always fixing any problems in a timely manner. In the long term this is what will save the customer time and money and achieve the best results.

Case in point:

When it comes to repairing and maintaining our asphalt surfaces, especially in this down economy, people tend to go with whatever is the cheapest solution. This, however, doesn’t always cause the intended outcome of saving money—rather one’s money is wasted due to poor quality work by the lowest bidder.

After meeting in the field with a customer regarding structural and drainage repairs to a parking lot, we sent an estimate detailing our scope of work. The next day our salesman received an irate phone call from the customer who accused him of price gouging because our price was almost twice that of the other contractor. We were both dumbstruck and curious as a result of these comments. Our pricing is always competitive if not consistently lower than our competitors. Had the customer made any attempt to compare the two scopes of work?

Suffice it to say that our curiosity got the better of us. A few weeks later our salesman was in the area of the parking lot and decided to stop by. The axiom, “you get what you pay for” comes to mind. The repair areas were holding water, not cut around the perimeters, and no milling was done at the curb and gutter to ensure an even transition. It looked as if someone had just quickly dug out the broken asphalt, backed a dump truck up full of new asphalt and dumped it in with no care.

Check out the "Bad Repairs" section of photos below and you be the judge. It will not be long before these repairs will have to be done again .

Bad Repairs:

19. There is mud coming through my blacktop, what can you do to repair it and why do I see mud.

2009-02-26T07:45:00.000-08:00

When answering this question it is important to first understand exactly how the mud got there and it all comes back to proper preventative maintenance. Typically, if you see mud showing through in your blacktop it means that water usually by way of a surface crack has penetrated beyond the gravel base and into the underlying soil layer. If this happens, mud can then be pumped up into the grave acting as a lubricant and causing the overlaying asphalt to shift as cars and trucks drive across it. You see this a lot in areas which have a vast amount of cracks and in many cases inadequate drainage.

The solution is a full depth replacement. Simply putting a patch over such a repair will only cover the problem temporarily, causing it to worsen. With a full-depth replacement our crew will come in tear out the damaged blacktop and gravel layer and replace it with new stone and newly laid asphalt. Important to note here – this fix among several others in many cases could have been avoided with proper asphalt maintenance, like crack filling and sealer, which studies prove can add up to 30-50% more life span to your lot, eliminating costly repairs.

What are the differences between patching, peel & pave, and mill & pave, what are the advantages or disadvantages to each one?

2009-02-25T14:37:00.000-08:00

Asphalt Patching
Patching is a common asphalt repair in areas where the asphalt has cracked, but the base is still stable, or in areas where potholes have occurred. This process begins by cleaning the repair area and applying a tack coat to help the new asphalt adhere to the existing surface. A layer of asphalt is then installed upon the existing surface; the depth will vary from 1”-2.5” depending on the severity of the existing damage. Patching is a cheap solution to asphalt defects; however it will not last as long as removal and replacement. Eventually cracking will reflect through the new patch, or spread beyond the patch.
Asphalt Removal & Replacement
Asphalt removal and replacement or as we call it “peel & pave” is another common repair. The repair is often prescribed for areas with cracking and or base/failure. This process begins by saw cutting the perimeter of the repair area in order to achieve a clean edge. After the edges are saw cut, the existing asphalt is removed to the depth specified. Typically the new asphalt is installed in 2 lifts; a binder course usually at 3” is followed by a 1” top course. The depth of repair will vary dependent upon the extent of existing damage, and/or the load requirements needed to be met. By adding up to 10 times more life span than patch work, asphalt removal & replacement is often a very cost effective fix for your surface’s distressed areas.
Mill & Pave
Milling, or grinding, takes a much different approach than either patching or peel & pave in that it removes built-up layers of deteriorated asphalt down to a specific depth, making room for a new surface, by actually grinding up the existing asphalt into a tiny like gravel. The millings, as they are often referred to are then hauled off site and can easily be recycled. The newly grinded surfaced is then layered with tack and set to receive a fresh smooth coat of asphalt. In many cases this type of fix is done on much larger areas where a peel and pave or patch is just not sufficient.

Cracks in Asphalt. Crackfilling and Other Forms of Repair

2009-01-19T09:59:00.000-08:00

The next 5 questions (13-17) from the top 50 paving maintenance questions are on the subject of cracking:

13. My lot has cracking can you repair the cracks?

14. What is the difference between normal cracking and alligator cracking?

15. What are my options for fixing the alligator areas?

16. You said there is reflective cracking in my lot, what is reflective cracking?

17. What are the advantages of repairing the cracks.

Although these are the common questions that we get, they really do not cover all the questions associated with cracking. This is a really big topic and from the perspective of someone who has spent over 30 years in the asphalt industry its an interesting one. This article is not intended to be definitive. I am trying to be informative to the typical property manager who is trying to deal with degrading conditions in their asphalt.

After spending some time on google, going through various journals and researching this subject in all the publication I have at my disposal, its clear to me that there is alot of information that covers this topic but not alot that pulls the whole topic together. Actually I didn't find any articles that did this. Even in the Asphalt Handbook you would have to pull alot of sections together to try to cover all the reasons for cracking. As a result there do not appear to be any ready reference guides to help property managers figure out what their problem is.

This article will attempt to give some insight into the issue. Lets start with the broad sweep and say cracking is a symptom of some sort of pavement failure. The question is why does pavement fail and does it always result in cracking? Not always but for the most part yes there is always some sort of cracking that occurs at some point with a pavement failure. Its worth repeating though that its not the problem. Its a symptom of the problem.

Pavement failures for three main reasons:

1. Surface Failures

2. Bonding Failures

3. Structural Failures

This provides a nice umbrella but it needs to be said that every crack or failure cannot be neatly classified into one of these categories. They often fall in between or in both.

Surface failures have to do with problems that occur in the surface layer of the asphalt. A common example of this is a crack that forms along a seam. Another example is cracking that water causes through erosion or deterioration of the asphalt. Oxidation or the effects from the sun would fall into this category.

Bonding failures are problems that occur between layers. Asphalt unraveling from layers not being tacked well together. Shoving or sliding that occurs at intersections where trucks always stop. Reflective cracking in my mind would fall into this group.

Structural failures are usually associated with the underlying stone base. Causes include weak or deficient base, excessive moisture, and lack of proof rolling procedures before placing the stone base.

Determing the cause of the crack usually will dictate the remedy. Normally crackfilling techniques can be used for surface failures and, on the other hand, would not be an acceptable remedy for structural failures. In the case of structural failures, it would be better to address the fundamental underlying problem by doing some sort of full depth repair.

Bonding failures could require either crackfilling or full depth repair but also might have other remedies that may be more appropriate. For example if asphalt is sliding or shoving the right remedy has to be determined by finding out what is the root cause. Asphalt might shove because the new surface was not properly tacked to the old, or its on a steep incline and the weight of the vehicles is pushing the asphalt, or there is something inherently wrong with the asphalt. Only someone with reasonable experience in these situations would be able to determine the cause. Generally an experienced geotech with roadtech experience would be able to determine the cause. There is no substitute for experience. A contractor who has dealt with these situations before would almost always have a good grasp of the problem and reasonably come up with a remedy that will work.

Be careful to consult a contractor that has the knowledge and technical skill to come up with the right remedies to problems. Our field estimators have alot of experience to draw from and if they don't know the answer they will get someone out there that does.

Sealcoating Questions - Questions 1-10

2008-12-01T08:40:00.000-08:00

The first 10 questions have to do with sealcoating.

Sealcoating is the process of placing a protective coating over the asphalt to help increase the life of the parking lot by reducing oxidation, protecting from gas and oil spills. Additionally it returns the lot to its original consistant black appearance which should probably be considered as an aesthetic benefit. Now lets try to answer the questions. The questions were not in any specific order. I will try to answer them in the order they were given to me which may not be the best.

1. How much will it cost?

Sealer pricing will range depending on size of lot, striping and number of coats. Depending on the lot the pricing is generally less pennies on the dollar compared to the cost of resurfacing or other repairs.

2. What is spider cracking on sealed lots?

Hairlines are very thin cracks, (usually less than 1/16th of an inch wide). They are cracks in the sealcoating, not in the asphalt itself. They are spider web looking, interconnecting cracks, and are usually more apparent when it is wet or damp out. This generally results from too many applications of coal tar products.

3. How did it happen?

We think it occurs because the coal tar cures differently than asphalt and as a result creates this incompatibility after successive applications. Check out this article: http://www.geeasphalt.net/asphalt_competitiveproducts.asp

4. What can I do to fix it?

Using asphalt sealer will generally improve the situation. If you begin sealing your lot with asphalt this problem will never occur. The only way to eliminate them completely would be to re-surface the parking lot.

5. Why should I seal my lot?

Why Seal Coat?

· Seal coating seals the asphalt pavement, preventing the oxidation and erosion of the top layer of asphalt

· On older pavements seal coating replaces fine particles lost from the asphalt surface due to oxidation

· Seal coating seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material.

· Seal coating helps protects the asphalt from the sun as well as the harmful effects of chemical spills such as oil and gasoline.

· Seal coating provides an attractive black surface that is ideal for painting lines and other markers.

· Seal coating leaves a smooth, clean surface ideal for sweeping, lowering cleaning costs.

· Seal coating costs pennies a square foot compared to the dollars needed to repair or replace damaged asphalt.

6. Are there alternatives to coal tar?

Yes there are asphalt based products that are the equivalent of coal tar based sealers and do not have the strong odor, acidic burning or carcinogenic effects.

7. What is coal tar?

Coal tar is a byproduct of the coking process. It is has been used as a preservative and in medicinal products that deal with lice and psoriasis. Coal Tar is thought to be carcinogenic and for that reason was banned in parts of California and Texas for use in sealcoating products. Here is the city of Austin's brochure on coal tar products: http://www.cityofaustin.org/watershed/downloads/brochure_coaltar.pdf

Here is another good article on coal tar that I think tells the whole story:

http://www.geeasphalt.net/asphalt_competitiveproducts.asp

8. What is asphalt sealer?

Asphalt sealer uses asphalt instead of Coal Tar to make a comparable sealcoating product.

9. What are the benefits of asphalt sealer?

Asphalt based products that are the equivalent of coal tar based sealers and do not have the strong odor, acidic burning or carcinogenic effects.

10. The other contractor said he is going to squeege the sealer. You are spraying. Whats the difference?

In our opinion spraying is the better method. It provides the more consistant coat across the entire surface (in terms of thickness) and without question produces the better finished look. Some websites question whether squeeging may be the better method. Maybe as a first coat application but its benefits are minimal. It is often view that this method does a better job filling cracks and voids. This is really a misnomer. Structurally sealcoatings do not do a good job to fill cracks since the resins in it are not flexible enough to deal with the movement in asphalt. As a result there is only minimal benefit to fill the cracks using the squeegee method. Squeegees tend to drag on the surface leaving the coating thin on the wear part of the surface where it is needed the most. Proper spray applied asphalts tend to outperform squeegee applied applications.

Spraying vs. Sealing is not the end of the story. There is one other method that is worth mentioning - Brush Application. "The bristles of the brush push the sealer deep into the pours and fill in all the little nooks and crannies. " (http://www.sealcoat911.com/about2.html),

The author of the above reference however recommends a squeegee application as the finish coat to the brush application. We have experimented with this and are not satisfied with this process. In our opinion there are 3 options to sealing:

1. 2 coat spray

2. 1 coat brush

3. 1 coat brush and 1 coat spray.

Number 3 is the best choice albeit the most expensive process. While the jury is still out our results indicate that 1 coat brush is better and slightly less expensive than 2 coat spray. But the brush / spray 2 coat process is by far the best.

50 Important Questions

2008-12-01T08:22:00.000-08:00

The Thanksgiving holidays are over and its time to get ready for Christmas. I always look forward to this slower time of year. In the construction industry the winter represents a time to take account of everything you did last year and how you would like to change things for the following year. I have been involved in this process since 1981, the year I was married. 5 children and almost 28 years later it has become a ritual that I can now look back on with some sentimental feelings for what seemed like a simpler time long ago.

When we decided to get this blog together, I asked for people within our company to put together lists of questions that our customer always ask. We felt that it would be another way for our customers to gain insight into our operations. My brother, David, took me up on this and put together a list of 50 questions that address issues that he answers all the time. So I thought I would simply list the questions in this blog entry and then over the next few weeks do my best to put some sort of an answer to each of the questions.

Keeping our options open

2008-11-14T04:32:00.000-08:00

Since we are a paving company, I would think that one of our responsibilities is to keep up on the latest technologies in our industry. So, in the spirit of ingenuity and forward thinking, I've done a bit of research on what else is out there when it comes to applications of asphalt in many different situations. One of the most interesting things which I've come across is pervious asphalt and what opportunities it offers as a way to mitigate stormwater runoff. The whole idea behind pervious asphalt is that stormwater is able to drain through the asphalt surface, down through layers of stone and sand which act to filter the water, eventually reaching the water table beneath the installed subgrade, and re-entering the water table as benign, filtered water. If engineers and planners were to embrace this technology and approve the use of these materials, site developers would be able to forgo the installation of expensive, and sometimes very complicated, detention ponds and other water runoff related structures. The biggest difference between the installation of pervious asphalt and traditional is in the sub-base. Pervious asphalt requires a layering of stone, sand and fabric, all of which is required to achieve the filtering necessary to clean the water before it re-enters the water-table. This does increase the price of installation, though costs are more than offset considering that detention ponds and other runoff related structures do not need to be installed.

The technology is rather new, and does have its drawbacks. One of which being that you cannot sealcoat pervious pavement, another being that it requires some maintenance in the form of a special vacuuming in order to keep the top asphalt layer from clogging up.

The University of New Hampshire has been studying pervious asphalt and has a wealth of information on its website dealing with it. Check it out here: http://www.unh.edu/erg/cstev/

As well here's a bit more info to take a look at: http://www.pavegreen.com/water_quality.asp

What is our companies purpose?

2008-11-10T09:44:00.000-08:00

This is a good question. On our websites home page, our mission statement reads:

"Our mission is to maintain excellent client relationships. We uphold our mission by providing clients with the best service possible along with superior construction, product quality and providing accurate project deadlines and budget estimates."

I think that is a good start but I am not sure it adequately defines our company purpose as it relates to all of our activities. I plan to revisit this question over and over again in this blog and talk about it in more ways than one. But as a general outline I think a company has different purposes as it relates to it's customers, it's employees and it's community. To adequately define all that in terms of a mission statement is pretty tough. If we start with our customers which is where I think we need to start then our Mission Statement sets us on the right track. To elaborate on it more I think we hope to produce a superior product but at the same time control costs and maintain efficiencies. I think that is the mark of a good company and what builds confidence with customers. There have been times where that doesn't always work out. Call it the nature of the construction business. That is what really makes the difference though. How you come through it. How well your company is able to react to diversity and get the job done. Perhaps a mistake gets made or we're not getting it done for some reason. Are we accessible? Can we adapt? Can we preserve the relationship and keep the lines of communication open? We can all make alot of claims when it is in a post on a website. So I guess our purpose then is to make our words into reality and deliver what we say when we say it.

Why do a blog?

2008-11-06T07:12:00.000-08:00

When it was suggested that I start a company blog for the website I really couldn't figure out why. The more I thought about it though the more I warmed up to the idea. What better way to give customers insight into our company. Not only from the point of view of who we are and what we do but to add a human face to all of that. We have been in business a long time and I am rightly proud of that. Our roots in the asphalt and construction industry go back to 1925. My 2 brothers and I have been in the business alone for over 30 years and now several of our children are involved. Many of our employees have been with us since the early eighties. We are still operating in Buffalo and now we also operate in Raleigh, NC. Almost 10 families have relocated here with us from Buffalo. For a small company of our size we have achieved a level of sustainable diversification that other companies simply cannot match because of the remarkable level of skill and talent that we possess. In the coming days, weeks, months...etc I hope to talk about many of the aspects of our business and how we make it work for our customer.
