道路交叉口处车辙病害防治的应用技术研究

Study on Application Technology of Rut Disease Control at Road Intersection

在上海市总体规划(2017-2035)中明确提到:优化城乡体系,形成“网络化、多中心、组团式、集约型”的空间结构。明确分类、分层、分级的空间指引策略,夯实“规土融合”的空间政策平台。由此可见,城市规划总体上遵循区域集中、产业分类、重点突出的原则,各个工业区在区域内集中设置,形成工业园区,因而导致连接各个工业区以及进出工业区的交通道路承载了较大的交通压力,重载车辆多,进而使得此类道路病害频发,尤其在各个道路交叉口,车辆的急停及起步加剧了病害的产生,其中车辙病害表现的尤为明显。主要研究灌入式沥青混凝土在处治道路交叉口车辙病害的施工工艺以及效果。

The optimization of urban and rural system is specified in Shanghai Overall Planning(2017-2035)to form the spatial structure of“network,multi-center,group type and intensive type”.The spatial guide strategy of specifying the classification,layering and grading tamps the spatial policy platform of“geodesic fusion”.It follows that the urban planning should follow the principles of regional concentration,industrial classification and emphasis on the whole.Each industrial area is centralized in the regions to form the industrial park,which results in the traffic roads connecting each industrial area and to-and-from industrial area bear the greater traffic pressure.There are many heavy-load vehicles,which make this kind of roads disease frequent,especially at each road intersection.The emergent stop and start of vehicles exacerbate the cause of diseases,in which the rut disease is especially obvious.The construction technology and effect of the poured asphalt concrete to treat the rut disease at the road intersections are mainly studied.
