摘要：
High temperature stability is one of thehighway performance of asphalt concrete. In order to better apply Supave-13, SMA-13 and AC-13C in high-grade highway pavement, and reduce the deformation of asphalt concrete pavement caused by insufficient high temperature stability, Supave-13, AC-13C and SMA-13 were subjected to dynamic stability test, uniaxial creep test, rebound modulus and compressive strength test. It was found that the dynamic stability of Supave-13 under the load of 0.7 MPa It was larger than SMA-13 and AC-13C; under the condition of 1.05 MPa load, the dynamic stability of Supave-13 was smaller than other ones; the stiffness modulus of Supave-13 mixture was significantly greater than that of the other two; rebound modulus of Supave-13 and AC-13C, were equivalent and greater than SMA-13; the compressive strength of Supave-13 was significantly greater than that of AC-13C and SMA-13; the compressive strength of both AC-13C and SMA-13 was equivalent. Comprehensive comparative analysis showed that the high temperature stability of Supave-13 was stronger than the other two asphalt mixtures. © 2020, Materials Review Magazine. All right reserved.
