PPRC14 SPE 4.51A: Binder Replacement in High RAP/RAS Asphalt Mixes (Phase 1: Literature Review and Laboratory Testing)
This study is a continuation of Task 2373 and Task 2565. The objective of this project is to develop guidelines for minimizing the risk of using high reclaimed asphalt pavement (RAP) and/or recycled asphalt shingles (RAS) contents in asphalt concrete mixes. This will be achieved in two phases: Phase 1 in Task 2676 and Phase 2 in Task 2677. Phase 1 includes: A literature review on research related to the topic; Preliminary laboratory testing to evaluate the rheological properties of fine aggregate mixes with different percentages of RAP and RAS and with and without warm-mix technologies and rejuvenating agents. There will be a summary report with recommendations for Phase 2 testing if appropriate.
