哈磴高速公路为减少公路早期损坏的实践

为了有效避免路面早期损坏，提出了使用改性沥青的方法，就哈磴高速公路沥青路面面层沥青混合料配合比设计进行了论述，实践证明，在半刚性基层上铺筑沥青混凝土，采用Superpave混合料设计方法与SBS改性沥青的使用，能够延缓沥青路面的早期病害。

The practice of decreasing highway incipient failure in Ha-Deng express highway

In order to avoid effectively pavement incipient failure,application modified asphalt method was proposed.It was discussed with Ha-Deng express highway pavement asphalt mixture proportion design,the practice proved that paving asphalt concrete over semi-steel base,the adopted Superpave mixture design method with applied SBS modified asphalt can prolong incipient failure of asphalt pavement.
