摘要
雾封层是一种沥青路面早期预防性养护技术。在沥青路面上喷洒专门配置的特制剂或乳化沥青稀释液,渗透到旧沥青路面中,使老化的旧沥青得以再生,提高旧沥青的路用性能指标,封闭道路表面的孔隙和微裂缝,抑制沥青路面的早期病害,改善路面外观,延长道路的使用寿命。该养护技术的施工工艺简单,开放交通迅速,在生产实践中值得推广使用。
Fog seal is a preventive maintenance technology for asphalt pavement in early stage.Through spraying exclusive specialized agents or emulsified asphalt diluents and permeating old asphalt pavement,the ageing asphalt can be recycled and improved on its service performance index.And meanwhile,the holes and micro-cracks of pavement can be sealed;early damages on the asphalt pavement can be controlled with improving pavement appearance and prolonging road service life.This maintenance technology shall be developed in practice because of its simple construction technology and quick normal traffic resumption.
