Abstract:Controlled field experiments were installed in north central and extreme south Texas to evaluate the comparative performance of six different additives in hot mixed asphalt concrete pavements. In north Texas, additives were incorporated in a 3-inch surface course which was applied to rehabilitate a continuously reinforced concrete pavement. In south Texas, additives were used in a 3-inch surface course on a newly constructed pavement. Additives evaluated included styrene butadiene rubber (latex), styrene butadiene styrene block copolymer, ethylene vinyl acetate, finely dispersed polyethylene, and pelletized carbon black. The additives were blended with AC-10; whereas the control mixtures contained AC-20.
