THE DESIGN AND QUALITY CONTROL INDEXS FOR WARM-MIX ASPHALT

摘要

In order to explore the suitable design and quality control indexes for Warm-Mix Asphalt, the WMA was compacted and the volumetric index was experimented by the method of Marshall Compaction. At same time, the pavement performance was tested such as the high temperature stability, low temperature anti-cracking and moisture susceptibility for the WMA compacted at the lowest temperature. The results show that the designing and constructed testing control indexes of WMA including put the TSR as the main control indicate of the water stability of WMA, put the residual stability as the reference and the flow value won't be used as the quality control indicate. With a lower mix temperature, the mechanical property and pavement property of WMA can meet the requirements of the specifications.
