Why Does Asphalt Pavement Deteriorate?

Friday, October 3rd, 2014

Why Does Asphalt Pavement Deteriorate?All good things must come to an end, as they say. The same holds true for your once proud asphalt pavement. Asphalt typically lasts from 15 to 18 years, depending on maintenance and outstanding conditions. Over the years, constant exposure to the elements – sunlight, rain, sleet, snow, and more – cause even the toughest asphalt to break down and eventually fail, resulting in cracking, potholes, or worse.

Why Does Asphalt Pavement Deteriorate?

Asphalt is known for its strength and durability, which is why the material is used for everything from roadways to parking lots. It’s easy to work with and capable of withstanding years of abuse. However, like all pavement (or anything for that matter), asphalt will begin to show its age over the years.

There are a few likely causes of asphalt pavement deterioration:

Natural Wear and Tear

Over time, the materials that make up asphalt begin to deteriorate. The liquid asphalt binder, the glue that holds the pavement together, begins to lose its natural elasticity and starts to break down. During this process, the asphalt also loses its natural resistance to water, making the pavement even more susceptible to rain, snow, freezing and thawing, and more. Once this happens, cracking and other forms of deterioration are not far behind.

Failures in Construction

Improperly installed asphalt can be a large reason for the deterioration of your pavement. Failures in construction can include: improperly compacted base, over or under compaction of the asphalt, improper temperature during application, poor drainage, and so much more.

Crack Sealing versus Crack Filling

Thursday, July 28th, 2011

Your pavement will eventually fail. It doesn’t matter how well you maintain your paved surface, it will eventually deteriorate and crack. However, how you deal with those cracks will determine how long your pavement will last. Sealing and/or filling cracks in existing pavement is the single the most effective procedure that can be performed to extend pavement’s lifecycle. This will prevent water and other foreign materials – sand, dirt, et.c – from seeping down into the asphalt where it can cause major distress and failures by weakening the base and sub-base.

This article from explains how filling or sealing pavement cracks is the most cost effective way to extend the life of your asphalt pavement.

Crack filling and crack sealing, while similar in nature, offer very different benefits.

Crack filling is less costly and will require less initial investment, but this solution may only be a temporary fix. Once the crack begins to move or expand, the crack filling material will lose its effectiveness and the crack will need to be re-filled. For this reason, crack filling is more effective in milder climates with less temperature change.

Crack filling materials include liquid asphalt, asphalt emulsions and cutbacks.

Crack sealing is a more costly option, but provides a longer life expectancy than crack filling – lasting 8 years or more. Crack sealing – which utilizes a flexible, specially prepared hot pour rubberized sealant – is considered a permanent treatment and is the only effective treatment for active cracks that contract and expand between seasons.

Crack sealing materials include asphalt rubber, rubberized asphalt, low-modulus rubberized asphalt and self-leveling silicone.

Benefits of Preventative Maintenance Pavement Sealers

Wednesday, July 6th, 2011

Even the best pavement will crack and deteriorate after time. But there are ways in which you can extend the life of your pavement. One of these ways, as this article from explains, is Pavement Sealer.

Asphalt hardening is an oxidation process and is a function of its exposure to air on the surface and within the pavement. If circulation of air through the interconnected void spaces in the pavement can be prevented or reduced, the rate of hardening of the asphalt will be slowed and the life of the pavement extended. Pavement sealers are used to do just that – close the surface pores to lengthen the life of the pavement.

Pavement sealers come in two basic formulas: Refined Tar-Based Sealer and Asphalt Based Emulsions.

Refined Tar-Based Sealer

Refined tar is a by-product of the distillation of crude coal tar. Refined tar differs from crude coal tar in that during the distillation process, the lighter end oils are removed from the refined tar. Refined tar based sealer is resistant to attack from petroleum based products. This property makes it ideally suited for parking lots or other locations where concentrations of oil and grease leaks are common. Refined tar-based sealer is also highly resistant to ultraviolet light bleaching. It is stable, homogeneous, easy to apply, and has been handled safely by professionals and do-it-yourselfers for decades. Refined tar based sealer has traditionally been used at gas stations, truck and bus terminals, airport aprons and taxiways as well as on residential driveways and commercial parking lots.

Asphalt based emulsions

Asphalt-based emulsions have many of the same beneficial properties as refined tar- based emulsions, but they are less resistant to corrosion by petroleum-based products, ultraviolet bleaching, and salts. An asphalt emulsion is a mixture of liquid asphalt and water. Manufacturers add special chemicals and pigments to the asphalt emulsions to improve performance but they remain susceptible to the damage caused by petroleum products.

Pavement sealers allow homeowners and businesses to maintain their asphalt effectively and economically. Research has shown that when asphalt pavement is maintained properly, the owner can extend the life of their pavement and delay costly reconstruction.
