山东省济青高速公路已通车11年,局部出现坑槽、网裂、车辙、平整度降低、抗滑性能差等病害,已严重影响了车辆的安全行驶。为确保路面的使用功能,经山东省基建股份有限公司考察后,决定试用微表处对经过预处理后的路面进行罩面处理,由河南省高远公路养护技术有限公司和江苏中邦微表处技术有限公司施工,试验成功后再在全线推广。试验段全长36.217Km,施工历时2个月。微表处混合料的施工性能受到诸多因素的影响,施工过程往往会出现较多的问题,且这些问题往往影响到成型后
Jiqing Expressway in Shandong Province has been in operation for 11 years and some pitfalls, net cracking, rutting, flatness reduction and poor skid resistance have caused serious impacts on the safe driving of vehicles. In order to ensure the use of pavement, the Shandong Provincial Infrastructure Engineering Co., Ltd. decided to try the micro-surfacing on the road after the pretreatment overlay from Henan Province lofty Highway Maintenance Technology Co., Ltd. and Jiangsu Zhongbiao Office Technology Co., Ltd. construction, test after the successful promotion across the board. The test section length of 36.217Km, construction lasted 2 months. The construction performance of the micro-surfacing mixture is affected by many factors, the construction process often has more problems, and these problems often affect the molding
