HA5® High Density Mineral Bond
Extend Asphalt Serviceability with a High Density Mineral Bond Surface Treatment
The Most Cost-Effective Strategy for Managing Asphalt Pavement
The most cost-effective strategy is one that considers the total cost of pavement ownership. Roads not preserved will see rapidly decreasing pavement condition. When it comes to preservation techniques, each treatment type has a different cost, lifespan, and impact on the extension of pavement life.
For qualifying roads, HA5 may be the most beneficial tool in your toolbox.
HA5 was developed to meet the demand for effective asphalt preservation on residential roadways without the negative side effects of chip seals or slurry seals. Specifically engineered to preserve the native asphalt binder, HA5 is exceptional at preventing oxidative damage. As a result, you will have streets that last longer and cost less to own.
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.
A Preservation Treatment with a 600%+ Return on Investment
Owners and managers responsible for asphalt roads and parking surfaces realize significant reduction in pavement lifecycle costs with HA5 due to the asset preservation qualities and durability of the installations. In use by public agencies nationwide, it is also the choice for school districts, religious organizations, medical providers, and various business types for asset preservation.
What is HA5?
HA5 is arguably the fastest-growing trend in pavement preservation, now in use by over 150 public agencies.
Meeting the stringent demands of a High Density Mineral Bond, HA5 is uniquely emulsified with a near neutral charge that is able to hold a unique 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 Ultraviolet (UV) radiation.
HA5 combats oxidation from UV by including limited amounts of specific polymers to reflect damaging UV rays.
Tested, Proven Performance
Research Showing 9X Less Cracking
People like black roads, but simply turning a road black does not necessarily equate to effectively extending the useful life of asphalt pavement.
Multiple professional engineers have independently evaluated HA5 installations. One report determined a significant reduction in cracking with HA5 when compared to a premium asphalt maintenance treatment and was identified as providing a much higher return on investment.
The evaluation compared HA5’s performance in a side-by-side comparison with another treatment. On one section, a commercially available polymer-enhanced asphalt emulsion was installed within a week of an adjoining HA5 installation.
The original paving of both sections was done as one project nine years before the side-by-side maintenance treatments were installed.
Each of the treated sections had multiple crack samples taken. The HA5 treated section had sample areas examined that calculated to an average .007 of the surface experiencing cracking and the polymer enhanced asphalt emulsion sampled road surface was found to have .06 of the area with cracking. That’s an astounding 857% more cracking in the non-HA5 treated pavement compared to the road having had HA5 installed.
