The design parameters are one of the important factors to ensure quality asphalt pavement design. In “Highway Asphalt Pavement Design Specification” (JTGD50-2017), stander China, used mixture anti-pressure resilience modulus at a single temperature 20 ℃ as metrics. However, mixture, sticky-bullet plastic material, shows different mechanical properties temperatures. China is vast territory, and there great differences between high low value (m n) each region. Therefore, it unreasonable only with ℃. Studies show that using PG technology can improve anti-rutting cracking performance pavement.
