I have been engaged in the research of asphalt pavement structure and materials for a long time, have a certain theoretical and experimental basis for the analysis of asphalt pavement structure behavior and material performance, and have mastered the research means of road material test and numerical calculation.
In order to deeply study the influencing factors and mechanism of interlayer contact of asphalt concrete pavement, some test methods are put forward, some test instruments are developed, and comparative test research is carried out.
It is found that the main factors affecting the interlayer bonding performance of asphalt concrete are tack oil, roughness of interface, cleanliness of interface, contact area at interface and temperature during test.
In terms of increasing the interfacial bonding strength of asphalt mixture, some process measures are proposed to strengthen the interlayer bonding.
At present, researches in this field are being done, and some research results have been published.
