采用水泥增强沥青的抗剥落性能

Improving Anti-Stripping Performance of Asphalt with Cement

沥青混凝土路面水损害的根本原因是沥青从集料上发生了剥落。试验表明 ,用水泥浆处理集料或用水泥取代部分矿粉 ,都能有效地增强沥青抗剥落性能 。

The moisture-induced damage occurs primarily because of stripping the asphalt from the aggregates. Tests show that the effective method for improving anti-stripping performance of the asphalt is to dispose the aggregates with cement slurry or replace the mineral powder by cement. However the technology of the latter is simple.
