Development of a Spray-Injection Patching System and a Field Performance Evaluation of 100% RAP Asphalt Mixtures using a Rapid-Setting Polymer-Modified Asphalt Emulsion

Laboratory Evaluation of Recycled Asphalt Pavement and Engineered Polymer Binder for Small Airfield Repairs

“…Cold patch products used on roadways are typically unable to support the high pass levels of aircraft with high wheel loads and tire pressures, particularly after only a few hours of curing [1,2]. Novel methods for producing small amounts of HMA quickly have been studied [3], including inductive HMA, which still requires specialized equipment, as well as a polymer-modified emulsion mixed with RAP that enables the repair product to be spray injected [4,5]. An alternative to HMA and cold patching is using an engineered polymer binder (EPB) mixed cold with recycled asphalt pavement (RAP) to produce a strong, durable repair with minimal equipment.…”
