چکیده انگلیسی
In asphalt concrete pavement layered system, interlayer bonding condition has significant effect on its behavior and performance. Bond condition between asphalt layer and semi-rigid base layer is more severe than others because of the different mechanical response under environmental and traffic loading. In this study, continuous construction method (CCM) is proposed to improve the bonding condition by increasing layers interlock depth. As a new construction method, the laboratory testing and field testing are conducted to understand the mechanism of bonding improvement. Quality control methods during the procedures of CCM are proposed. Optimal initial compaction degree of the base layer and paving time interval between base layer and asphalt layer are suggested for better bonding condition. According to the results of field crack survey and deflection testing, CCM can reduce transverse crack number and deflection level with better bonding condition between asphalt layer and semi-rigid base.
