沥青路面产生不平整的原因及处理措施

Reasons for the unleveling phenomena appeared in the asphalt pavement and treatment measures

随着高等级公路的迅速发展,对于路面平整度要求越来越高,路面平整度的合格率既反映了行车舒适程度,又反映了施工队伍的水平。文章就沥青路面平整度的控制,从施工人员素质、路基施工质量、桥头涵洞两端及桥梁伸缩缝的处理、路面底基层及基层的施工等方面进行了深入的分析,在此基础上提出了如何保证和改善路面平整度的相应措施。

In the construction of higher grade highways,the leveling degree of pavement,which is an important factor for achieving a higher degree of driving comfort,reflects the level of a construction crew to some extent. In view of the control of the leveling degree of asphalt pavement,an analysis is made of the main causes of the unleveling phenomena,and corresponding measures for guaranteeing and improving the leveling degree of asphalt pavement are presented in detail. The discussion is mainly focused on the constructor's qualifications,the subgrade construction quality,the treatment of the ends of bridgehead and culvert,the treatment of the bridge expansion joints,the construction of the pavement base and subbase,and the technological control of paving and rolling.
