What is HA5 asphalt?
HA5™ Asphalt Preservation 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.
What is HA5 in road construction?
What is HA5? HA5 is a High Density Mineral Bond uniquely emulsified with a near-neutral charge that is able to hold exceptionally high concentrations of fine aggregates and other components that resist deterioration. Limiting oxidative damage from moisture is fundamental to HA5’s preservation qualities.
What is a high density mineral bond?
High Density Mineral Bond (HA5) was specifically engineered to preserve relatively new asphalt surfaces through denial of oxidative damage at the surface by UV rays and within small cracks and fissures created by moisture infiltration.
What does HA5 do for your skin?
SkinMedica HA5 Rejuvenating Hydrator rejuvenates skin with the power of 5 different forms of hyaluronic acid. This hyaluronic acid serum also helps minimize the appearance of fine lines and wrinkles. Five forms of hyaluronic acid work to immediately smooth skin and provide eight hours of continuous hydration.
How often should I use HA5?
When to Apply Apply twice daily—in the morning and at night—after cleansing, toning, and treating your skin. Apply before you moisturize and apply SPF (sun protection).
How long does a bottle of SkinMedica HA5 last?
The full size usually lasts me about 6 weeks with liberal twice a day use.
What is the role of Ha5 in asphalt preservation?
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.
How much cracking is found in Ha5 treated asphalt?
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.
Which is the fastest growing trend in pavement preservation?
HA5 is arguably the fastest-growing trend in pavement preservation, now in use by over 200 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.
Which is the most cost effective asphalt surface treatment?
Extend Asphalt Serviceability with a High Density Mineral Bond Surface Treatment The most cost-effective strategy is one that considers the total cost of pavement ownership. Roads not preserved will see rapidly decreasing pavement condition.
