In situations of continuous multi-layer construction of the asphalt concrete core wall at high temperature climate of summer, it is required to wait for the joint surface temperature to reduce to the upper limit of 90℃ according to the specification. In order to shorten the waiting time, indoor tests were conducted to simulate the scenario of paving two consecutive layers of the core wall with increased joint surface temperature. we studied the compaction and deformation of asphalt concrete with the joint surface temperature of 90℃, 100℃ and 110℃ and verified the results with in-situ tests. The results showed that when the binding surface temperature of the core wall asphalt concrete reduced to 100℃, the porosity rate of the upper asphalt concrete was 2.88%, and the maximum lateral strain of the lower asphalt concrete was 2.78%. Whereas the porosity rate of the upper asphalt concrete was 3.85 % and the maximum lateral strain of the lower asphalt concrete was 4.0% when the joint surface temperature was 110℃. The in-situ field results indicate that the porosity rate and permeability coefficient of the upper asphalt concrete at the joint surface temperature of 100℃ can meet the specification requirements. Therefore, when multi-layers of the asphalt concrete core wall are being compacted continuously with increased joint surface temperature of 100℃, the construction quality can be guaranteed.
