AROS(Anisotropic Rubber Obviated Stress)
 

What is AROS™?

Anisotropic - Dissimilar physical properties along non-parallel axes.

Rubber - Powdered scrap tires crosslinked with grafted virgin elastomers.

Obviated - To anticipate and dispose of effectively.

Stress - A force applied to an object.

 

Simply stated; AROS™ Technology is vested in the science of processing and assembling cost effective materials which will defeat stress; thereby rendering such materials significantly more durable. This includes stress from all sources including: sun, rain/water, chemicals, thermal influence, mechanical loads and molecular entropy. Whenever infrastructure is constructed or defects are repaired using AROS™ engineered materials that infrastructure will last longer, usually much longer than the best current alternative. Making the AROS™ ‘durability choice’ will maximize the financial return from the asset investment.
 

Hot applied Asphalt Rubber binder technology (ASTM D6114-97) has a thirty year proven, superior performance record when installed in road construction and maintenance systems. Whether it be SAMI/chip seals or full, hot mix pavement cross-sections the fatigue resistance and overall safety and durability of the Asphalt Rubber pavement sets the standard. ARB is now available as an emulsion.

The innovation has a patent pending and is referred to as AROS™ (Anisotropic Rubber Obviated Stress). The base thermoplastic adhesive consists of a finely ground tire (80-140 mesh) immersed and reacted in a waterless, up to 350°F polymer modified asphalt. The reacted hot rubber adhesive is then compounded with a proprietary emulsion. AROS™ can be formulated as a coating, sealant and/or adhesive which will cure quickly to a non-tracking, water resistant binder or surfacing element with superior resistance to; oxidative hardening, weather or mechanical wear. It may also be formulated to cure at non-traditional winter temperatures down to 40F and; at night.

The AROS™ formulary includes use as:

  • HMA primer
  • SAMI primer
  • SAMI chip binder
  • Rejuvinating sealer
  • Fog seal
  • Skid resistant traffic lane sealant-surface binder
  • Seal coat binder
  • Type I, II, III, or Micro slurry binder and/or
  • Cold mix adhesive inclusive of RAP. 

The AROS™ may also be formulated as a 1) D1227 Type III, B roof membrane, 2) submerged membrane liner, 3) flashing cement, 4) steel or concrete pipe coating and/or 5) waterproofing mastic(s).

Performance data and samples are available for various applications. Multiple manufacturing locations will make material available beginning in February 2009.
