由于设计、施工、养护等因素的影响,机动车水泥混凝土路面易产生裂缝,尤其在车辆荷载的往复作用下,裂缝是影响水泥混凝土道面安全行驶的关键因素,当裂缝严重程度达到一定的值后,混凝土板的承载力就会全部丧失,对汽车的行车安全、舒适度产生不利影响。首先对机动车道面早期裂缝的形成机理进行分析,然后对表现形式进行阐述,最后根据不同裂缝系统提出了灌浆修补法和开槽修补法,这些方法较好的满足道面早期裂缝处理的相关技术要求。
Due to the influence of design, construction, maintenance and other factors, the cracks easily occur on the cement concrete pavement of vehicles, especially under the vehicle reciprocating load. Cracks are the key factors affecting the safe driving of cement concrete pavement. When the severity of cracks reaches a certain value Afterwards, the bearing capacity of the concrete slab will be completely lost, which will adversely affect the driving safety and comfort of the vehicle. Firstly, the formation mechanism of the early cracks in the road surface of the vehicle is analyzed, and then the manifestations are expounded. Finally, grouting and grooving methods are put forward according to different fracture systems. These methods are better to meet the related technology of early crack treatment in pavement Claim.
