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. While it is essential to prevent oxidative damage from moisture, it is just as critical to protect against oxidative damage on asphalt from UV rays. HA5 combats oxidation from UV rays by including limited amounts of specific polymers to reflect damaging UV rays.
To put it simply, HA5™ (categorized as a High Density Mineral Bond) provides an armor - like shell with exceptionally high durability that extends the life of an asphalt binder by resisting oxidative deterioration. HA5 combines uniquely emulsified asphalt with a near - neutral charge that is able to hold exceptionally high concentrations of fine aggregates and other components that resist deterioration. HA5 also contains a protective barrier from ultraviolet rays which accelerate pavement deterioration.
