沪嘉高速公路为新线高路堤,全线处于软土地基的不利条件。在软土地基上修筑高路堤存在着路堤稳定和路面沉降问题,高速行驶的安全又对路面面层摩阻抗滑提出了更高要求。为此,本文根据设计要求,为沪嘉高速公路制定了从路基直至路面层施工操作规程和质量标准;并就路基路面设计中有关路基压实度的确定、原地面处理及路堤横坡要求、路基回弹模量及要求弯沉值、基面层结构组合及弯沉值、沥青砼防滑层材料要求及级配组成、中央分隔带和路面排水、路面抗滑摩阻值等方面作了简介。
Shanghai-Jiaxing Expressway as a new high embankment, across the board in the unfavorable conditions of soft ground. The embankment stability and pavement settlement exist in the construction of high embankment on soft soil foundation. The safety of high-speed driving also puts forward higher requirements on the friction and slip resistance of road surface pavement. For this reason, according to the design requirements, this paper formulates the operation rules and quality standards for the construction of Shanghai-Jiaxing Expressway from subgrade to pavement; and on the determination of subgrade compaction degree, original ground treatment and embankment cross-slope requirements in the design of subgrade and pavement, The subgrade resilience modulus and the required deflection values, the composition and deflection of the base surface structure, the requirements of asphalt concrete anti-slip layer material composition and gradation composition, the central divider belt and the road surface drainage, pavement slip resistance values were introduced .
