Use of SBR (Styrene-Butadiene Rubber) Latex for Improvement of Recycled Asphalt Pavement
Styrene-butadiene rubber (SBR) latex was added to cold-milled, recycled hot-mix asphalt concrete in order to improve the fatigue properties of the mix. Samples were tested by repeated load indirect tensile tests and analyzed by the VESYS Structural Subsystem computer model. Four different pavement materials and two different latices were tested. The basis for comparison is VESYS 'life', a predicted time to reduce predicted present serviceability index to 2.5. Since the major improvement area is reduction of the rutting component of damage, excessive stiffness of the treated recycled mix may remain a problem, but full-scale testing is justified.
