Evaluation of Asphalt Rubber Binders in Porous Friction Courses
This report documents a laboratory research effort to determine the potential benefits of asphalt rubber binders when used in porous friction courses. The results of this research study are also used to recommend the asphalt cement grades and mix design procedure required to achieve optimum field performance. This study was conducted as part of a joint research project between the US Army Corps of Engineers and the Asphalt Rubber Producers Group (ARPG) under the Corps' Construction Productivity Advancement Research (CPAR) program. Other CPAR research studies relating to asphalt rubber pavement systems were conducted under ARPG contracts and are documented separately from this report. The laboratory tests conducted at the US Army Engineer Waterways Experiment Station included physical tests on various grades of asphalt rubber and asphalt cement binders. Accelerated aging tests were conducted on the binders to determine short- and long-term aging tendencies. A mix design analysis and several physical tests were conducted on open-graded mixtures containing the asphalt rubber binders. The results of this study indicated that porous friction courses made with asphalt rubber binders would be more durable, longer lasting, and better water draining pavement layers when compared with unmodified asphalt cement -porous friction courses. Asphalt cement grades between the AC-5 and AC-20 Asphalt modifiers, Open-graded pavement, Asphalt rubber, Pavement construction, Hydroplaning, Pavement design, Porous friction course, Recycling, Skid resistance.
