首先分析路面施工过程的特点,总结了产生离析的主要环节及在抗离析方面上的缺陷。通过对转运—摊铺施工工艺及大宽幅螺旋全埋摊铺施工工艺的对比分析,说明了现代摊铺施工技术对改善不同阶段离析的控制效果。根据江西省某高速公路的施工检测资料,证明应用大宽幅螺旋全埋摊铺工艺控制沥青混凝土路面离析是完全可行的。
First of all, the characteristics of pavement construction process are analyzed, the main aspects of segregation and the defects in anti-segregation are summarized. Through the comparative analysis of transport-paving construction technology and large-width spiral full-buried paving construction process, the control effect of modern paving construction technology on improving segregation at different stages is illustrated. According to the construction inspection data of an expressway in Jiangxi Province, it is proved that it is feasible to control the asphalt pavement by using the full width spiral full buried paving process.
