The cause and control of the early crack of pitch and mixed material pavement

沥青混合料面受多种因素的影响，早期产生不规则裂缝是当前普遍存在的现象，根 据对基层、温差、预留孔洞、沥青混合料质量等原因的分析，提出了加强沥青路面的多方面 综合控制的措施。

For pitch and mixed material pavement affected by many factors, th e anomalous crack appears commonly in early stage. This paper puts forward the c omprehensive countermeasures of strengthening pitch pavement according to the an alysis on the basal plate, difference in temperature, preformed hole, and qualit y of pitch and mixed material.
