Study on Comprehensive Evaluation Method of Crack Resistance of Hot Recycled Asphalt Pavement
In order to better evaluate the crack resistance of hot recycled asphalt pavement,semi-circular bending test and direct tensile test were used to evaluate the crack resistance of hot recycled asphalt mixture and recycled asphalt mortar respectively.The correlation of different crack resistance indexes was analyzed,and the crack resistance of hot recycled asphalt pavement was proposed at multiple scales.The results show that there is a high consistency between the fracture energy of recycled asphalt mortar and the fracture work and fracture energy normalization value of recycled asphalt mixture at 20 ℃,which indicates that the fracture energy of recycled asphalt mortar can effectively predict the fracture resistance of recycled asphalt mixture.
