HA5 is a High Density Mineral Bond uniquely emulsified with a near neutral charge that is able to hold a proprietary blend of fine aggregates.
Limiting oxidative damage from moisture is fundamental to HA5’s preservation qualities. But just as critical to the prevention of oxidative damage from moisture is preventing oxidative damage from UV rays. UV rays are strong throughout the western U.S., especially in higher elevations as well as desert regions.
HA5 combats oxidation from UV rays by including limited amounts of specific polymers to reflect damaging UV rays.
In 2009, an evaluation was conducted that compared the oxidative damage of an asphalt street having HA5 installed to an adjoining street not having HA5 installed. The pavements evaluated were both 11 years old, with one having had HA5 installed at year six. The pavement with HA5 installed had 400% less cracking.
For HA5 to be properly installed, specialized equipment is required that can uniformly disperse a thixotropic material housing the required density of fine aggregate.
HA5 installations are backed by a five year warranty.
