Thinlay Asphalt Concrete
THINLAY ASPHALT CONCRETE is a pavement preservation material. The THINLAY specification was developed for use on all traffic applications ranging from interstate highway to arterial pavement and low volume rural roads. It provides a value-competitive alternative to chip sealing and microsurfacing all the while providing a superior driving experience. A THINLAY pavement surface is smooth, eliminates dust, is free of loose stone chips, and is quiet and completely reusable into new asphalt pavement.
THINLAY ASPHALT CONCRETE is a minimum 3/4-inch thick asphalt overlay that preserves a pavement by correcting minor surface distresses, provides increased pavement strength that resists pavement fatigue, enhances ride comfort, and improves road profile and driver safety. (Note: A variable-depth intermediate course is recommended where profile or crown are excessive.)
THINLAY ASPHALT CONCRETE is non-proprietary and can be furnished by any asphalt producer. THINLAY is produced as either a hot mix asphalt or warm mix asphalt product.
THINLAY ASPHALT CONCRETE has been designed to be rich in asphalt binder, fine-textured with a tight surface matrix to resist aging. THINLAYs used in lighter traffic applications require a softer grade asphalt binder (PG 58-28) and a minimum of 50 percent of the virgin fine aggregate to be natural sand. This facilitates attaining mix density, flexibility, and resilience. These are necessary properties for ensuring longevity and successful mix performance on light traffic roadways where oxidation and cracking are the primary pavement distresses.
