• Abstract:
  This project evaluated many softer but polymer-modified asphalt binders (PGxx-28 and PGxx-34) in both laboratory and field test sections. Binder tests, such as the multiple stress creep recovery (MSCR), linear amplitude sweep (LAS), and pure linear amplitude sweep (PLAS), were performed to evaluate binders’ rutting and cracking resistance. Mixture tests, such as the Hamburg wheel tracking test (HWTT) and overlay test, were conducted to compare and validate binder test results. Field performance data from multiple test sections in 10 TxDOT districts were surveyed and analyzed. Based on the laboratory test results and field observations, a revised asphalt binder grade selection catalog is recommended and validated. In addition, asphalt binder quality was evaluated using IDEAL Cracking Test (IDEAL-CT) with a focus on aging and cracking resistance.
