Research on shearing performance of asphalt mixture with Lucobit

Abstract

Abstract. To study the shearing performance of asphalt mixture with Lucobit, AC-13C and SUP-20 asphalt mixture with Lucobit were carried out the uniaxial penetration test and the the direct shear test. The results show that the angle of internal friction of the same gradation and temperature has little difference, cohesion force of the same asphalt decrease with the rising of temperature at the same graduation, and Lucobit modifier can greatly improve the shearing performance of asphalt mixture for both AC-13C and SUP-20.
