Abstract:
In order to effectively improve the high temperature stability of the asphalt pavement, the asphalt mixture rutting
specimens without embedded and with embedded heat pipe were prepared based on the principle of the gravity heat pipe
cooling. The heating and cooling processes of the rutting specimens were simulated by an oven. The temperature sensor and
temperature gun were used to collect the temperature data at different positions of the rutting specimens in real time. The
enthalpy change value and temperature gradient in a specific calculation range was analyzed to study the effect of heat pipe
on the cooling characteristics of the asphalt mixture rutting specimens. The influence of the heat pipe on the rutting
resistance of the asphalt mixture was studied. The results show that the heat pipe can adjust t
