Abstract

This paper analyzed the causes of different efflorescence phenomena and determined that the pressure difference was the main driving force of efflorescence. A self-designed critical pressure difference test was conducted to analyze the anti-efflorescence performance of asphalt mixture under different compaction methods and gradation types, and it was proposed that “critical pressure difference”, “time to start pumping at 2 kPa”, and “pumping amount at 2 kPa for 3 min” could effectively evaluate the anti-efflorescence performance of asphalt mixture. The results show that the anti-efflorescence performance of the asphalt mixture is ranked as follows: rotary compaction forming, Marshall compaction forming, and wheel grinding forming. In the gradation design, the anti-efflorescence performance of SMA is better than that of AC, and a larger aggregate size indicates better anti-efflorescence performance.
