  • What Causes Asphalt Pavement to Fail?


    Assuming that the initial asphalt pavement was designed and constructed properly, the primary cause of failure is the penetration of water into the asphalt base. Oxidation of the pavement surface begins this process which caused the asphalt to dry and become brittle. This oxidation leads to the erosion of the top layer of fine particles and the appearance of larger stones and small cracks on the surface. If left untreated, these cracks grow over time and eventually allow water to penetrate to the base of the pavement. When water enters the base of the pavement, the base material moves and settles leading to further cracking and an "alligator appearance." When the pavement reaches this stage the only option is removal and replacement of the old asphalt, which costs the most.

    In short, your Asphalt Pavement will fail because of AIR & WATER, unless you are proactive to maintain the surface & extend the life of the asphalt. Like Death & Taxes, Air & Water are unavoidable to your asphalt pavement. Whatever the condition of your Asphalt Pavement is, if you want to keep your overall costs down, you will need to implement a plan to maintain your asphalt pavement before it has to be replaced!

    What is Sealcoat?

    Tri-State Asphalt's sealcoat is a coal tar pitch emulsion that meets Federal spec ASTM D 5727-00, standard Specification for Emulisified Refined Coal tar (Mineral Colloid Type). Sealcoats are applied directly to the surface of an asphalt pavement.

    Sealcoat serves to seal the top of the asphalt, preventing water from penetrating the surface of the pavement and protecting the top layer of asphalt from oxidation and wear caused by exposure to the sun and air. Sealcoat also beautifies the pavement by providing a smooth, black, and even surface ideal for painting lines and sweeping.

    Sealcoat is designed for off highway use where there are low traffic speeds and tight turning radiuses such as parking lots, mobile home parks, schools, shoulders, etc. Sealcoats are different from slurry seals which use a much coarser aggregate filler and are designed for use on high speed areas with straight rolling traffic.

    How does Sealcoating help?

    Sealcoat seals the asphalt pavement, preventing the oxidation and erosion of the top layer of asphalt. On older pavements Sealcoating replaces fine particles lost from the asphalt surface due to oxidation. Sealcoat seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material.

    Sealcoat helps protect the asphalt from the sun as well as the harmful effects of chemical spills such as oil and gasoline. Sealcoating provides an attractive black surface that is ideal for painting lines and other markers. It also leaves a smooth, clean surface ideal for sweeping, lowering cleaning costs. Sealcoat costs pennies per square foot compared to the dollars needed to repair or replace damaged asphalt

    When Should Sealcoating be Done?

    Generally you should wait a few months before sealing new pavement to allow it time to cure. Tri-State Asphalt recommends waiting 6-12 months before Sealcoating new pavement. After a surface has been sealed it should be re-sealed every 3 - 4 years or as necessary.
