Evaluation of Recycled Asphalts by Shrp Binder Specification
نویسندگان
چکیده
Recycled asphalts were evaluated based on SHRP binder specification. DSR (Dynamic Shear Rheometer) and BBR (Bending Beam Rheometer) tests were carried out on samples of the recycled asphalts under three conditions: original binder, RTFOT (Rolling Thin Film Oven Test) residue and RTFOT+PAV (Pressurized Aging Vessel) residue. PG (Performance-Graded) classification was conducted. New straight asphalts at which the recycled asphalts are aimed with a same penetration were also tested as control samples. It is indicated that there is no significant difference between the recycled and the controlled samples for the obtained results. It is suggested the agent for asphalt recycling is effective with respect to the SHRP specification.
