Journal Title: 河南科技大学学报（自然科学版） - Year 2018, Vol 39, Issue 3
Abstract
In this paper, the mixing rubber asphalt was prepared by car tire rubber powder which was made in the double screw cold extrusion, and the gradation designs of the SMA-13 rubber asphalt mixture were made.Based on experiments of the pavement performance, the influence on the pavement performance of different dosages ( 20%, 30%, 40%) of extruded rubber powder in rubber asphalt mixture was investigated and estimated. The optimum content of rubber powder was proposed. The experimental results showed that the pavement performance of the mixture can be obviously improved by extruded rubber powder. When the content of rubber powder is 30%, the dynamic stability of the mixture is 3 398 times/mm, the maximum bending strain at break is 2 866 με, the residual water immersion stability is 107. 71%, the freeze-thaw splitting strength ratio is 77.6%. Therefore, the comprehensive performance of 30% mixed rubber asphalt mixture is optimal.
