Abstract
In order to improve the interlaminar mechanical properties of semi-rigid layer and asphalt layer in asphalt pavement, the method of the base surface treated pits was studied and their properties at different temperatures were explored. The experimental results show that at 20 °C, compared with the base surface untreated, the interlayer shear strength of the base surface treated 9 pits of q>20 mm was increased by 27.95%, and the tensile strength was increased by 57.51%. Within a certain range, increasing the diameters of the pits can improve the bonding effect between the layers. In the temperature range of 0 °C-40 °C, the interlayer bonding effect of the base surface treated 9 pits of q>20 mm and spread oil is been better than the other three interlayer treatment methods in the experiment. These results show that the base surface treated the pits can form mortise structure, which can improve the mechanical properties between layers and weaken the negative effect of high temperature on the adhesion between layers.
