Estimation method for sequence of voids in mineral aggregate of asphalt mixture
The invention relates to an estimation method for the sequence of voids in mineral aggregate of an asphalt mixture. The estimation method comprises the following steps: firstly, based on mineral aggregate without asphalt, establishing physical models of voids in mineral aggregate in a skeleton void form, a skeleton dense form and a suspension dense form, and analyzing a change rule of voids in the mineral aggregate without asphalt; and verifying the sequence predicted by the models according to a result of test on voids in mineral aggregate of a compact asphalt mixture. With the method, the trouble of obtaining voids in mineral aggregate by a Marshall compacting or rotary compaction piece is eliminated, the test workload is reduced greatly, the design efficiency is improved, and feasible theoretical and technical support is provided for grading optimization design of asphalt mixtures.
