摘　　要：沥青路面早期损坏的原因是多方面的,在处治上应从加强结构研究入手,首先形成嵌挤骨架结构,提高抗变形能力;使用改性沥青改善高温稳定性,提高骨料间的粘结力;同时,还要加强施工管理,严把质量关。这样,沥青路面的早期损坏是可以预防和减少的。There are many reasons in breaking of pitch surface in early stage.We would study them and find a way to reinforce a construction.Firstly,we make it as a skeleton with a capacity of anti-de-formed.The improved pitch could reform the stability in high temperature and enhance the capability in stick between the bones.Otherwise,it should enhance the management and keep the quality.If it did,the breaking of pitch surface in early stage could prevent and reduce.
