Evaluation of Cracking Resistance of Recycled Asphalt Mixture Using Semi-Circular Bending Test
The objective of this laboratory study is to utilize the semi-circular bending (SCB) test to evaluate the effect of reclaimed asphalt pavement (RAP) on the cracking resistance of asphalt mixtures. Two type of SCB test, the tensile strength and the fracture test, were conducted on a gravel mixture containing four percentages of RAP. The results show that RAP generally increased the SCB tensile strength but significantly decreased the post-failure tenacity of asphalt mixtures. RAP also decreased the J-integral of asphalt mixture and therefore its cracking resistance. Both short-term and long-term aged asphalt mixtures exhibited similar trend in evaluating the effect of RAP.
