Description
[0001] 【Technical field】 [0002] The invention relates to the technical field of asphalt pavement testing, in particular to an indoor simulated asphalt pavement heat absorption device and method. [0003] 【Background technique】 [0004] Asphalt concrete pavement is the main pavement structure form of expressways in our country, accounting for more than 90% of all pavement forms, but the rutting phenomenon of asphalt pavement seriously affects the performance of asphalt pavement. Rutting is mainly produced in high temperature in summer. In order to reduce the occurrence rate of rutting, in recent years, many scholars and researchers have been conducting research on the cooling technology of asphalt pavement, which requires the heat absorption of asphalt pavement before and after cooling measures under the most unfavorable conditions. experiment. [0005] Due to research requirements, time and weather constraints, the heat absorption experiment of asphalt pavement can only be c...
