摘要
半刚性基层的裂缝反射至沥青面层会导致沥青路面水损坏。为防止路面水渗入基层,可通过铺筑防水抗裂层结构达到封水、抗裂的目的。鉴于此,对防水抗裂层用沥青及沥青混合料的性能进行研究分析,试验路的运营状况表明该层对防止沥青路面水损坏具有良好的效果。
The cracks of semi-rigid base reflecting to asphalt surface will cause water damage on the as-phalt pavement. Waterproof and anti-crack layer can prevent water into the base to achieve the purpose of sealing water and anti-crack. Given this, the paper studies the function of asphalt and asphalt mixture used in waterproof and anti-crack layer. The operational status of test road proves waterproof and anti-crack layer can well prevent the water damage of asphalt pavement.
