对上海S32高速公路的路面性能检测和综合评价

Inspection and Comprehensive Assessment of Pavement Performance of S32 Expressway in Shanghai

根据交通运输部行业和上海地方标准,对上海S32高速公路南进场段进行了现场检测,包括路面行使质量指数、车辙深度指数、抗滑性能指数、结构强度指数、渗水系数^([1])。通过各项路面试验检测数据进行汇总分析,对路面的使用性能进行综合评价,并对路面各种病害产生的原因进行了讨论。建议应尽可能的在路面结构良好,或病害产生的初期时段采取相应的预养护措施,防止路面病害进一步扩大。

The pavement performance of south approach section of the expressway, S32 in Shanghai has been evaluated based on a variety of field test items, including riding quality, rutting depth, skidding resistance, structure strength indexes water permeability coefficient, according to the technical standards issued by Ministry of Communications as well as Shanghai. The reasons for pavement disease are discussed. Preventive maintenance should be implemented in the period that the pavement is still in a good structure or in the early stage of the pavement disease , in order to prevent the disease development.
