Abstract
According to the phenomenon of pavement cracking in low temperature in Northeast China, AC-13I and AK-13I of the two gradations, SBS, Methyl Cellulose fiber and steel fiber are adopted to research the mechanics parameters of reinforced asphalt mixture by Indirect tension test at minus 10 degrees centigrade entering on pavement material. Improvement of the low-temperature indirect tensile strength, stiffness and deformation capacity of asphalt mixture is analyzed and mechanisms are revealed. The results indicate that low-temperature crack resistance of steel fiber-reinforced AC-13I asphalt mixture is improved significantly, it is better for the cold area in Northeast.
