公路扩建工程路面搭接技术研究

Study on Pavement Lap Technology of Highway Extension Project

依托实际工程,对原路段的交通量和路面病害进行研究,并对路面搭接技术中的铣刨技术进行重点分析。通过对搭接路面进行原材料检测、平整度检验及车辙试验,得出搭接竣工后3段试验路面平整度满足行车舒适性、高温性能高于原路面,且满足施工要求。

Based on the actual project,the traffic volume and road surface disease of the original section are studied,and the milling technology in the road surface lap technology is analyzed emphatically.Through the testing of raw materials,flatness inspection and rutting test,it is concluded that after the completion of the lap road,the flatness of the test road in three sections meets the driving comfort,the high temperature performance is higher than that of the original road surface,and meets the construction requirements.
