Compaction Characters of Asphalt Mixture of Variable Thickness
Compaction characters of variable thickness screed-coat material were investigated during the process of old cement road reconstruction. The compaction characters of asphalt mixture of variable thickness were studied under gyratory compaction test. Results show that asphalt mixture ATB 25 with different initial thickness have the same compaction character. However, residual void ratio of asphalt mixture with different initial thickness is different under the same compaction times. Based on void ratio of design and the relationship of compaction times and remaining void ratio, the relationship of compaction times and initial thickness was established. Through the results of gyratory compaction test, the optimum compaction temperature of ATB 25 is confirmed to be 140.
