| Abstract: | Three point bending tests were performed using unnotched specimens to assess the effects of fiber length to cracking resistance at low temperature, and the reinforced mechanism of cracking resistance was analyzed. The result shows while adding fiber to asphalt mixture can effectively improve its low temperature performance, enhance cracking resistance of asphalt mixture. |
