沪宁高速公路改扩建工程采用以“两侧拼接加宽为主、局部分离加宽”的施工方法,要求在不改变原沪宁高速公路技术标准的情况下将老路扩建为八车道。鉴于目前尚无高速公路拓宽工程的设计与施工规范可循,采用聚酯玻纤布对高速公路新、旧路面半刚性基层拼接施工或旧沥青混凝土路面面层铣刨维修后的拼接缝或裂缝进行处理,能有效防止反射裂缝产生和水破坏,就此对聚酯玻纤布性能及施工工艺进行分析研究。
Shanghai-Nanjing Expressway expansion project using “widening of the main splicing on both sides, partially widened” construction methods, requiring the original Shanghai-Nanjing Expressway without changing the technical standards of the old road expansion into eight lanes. In view of the fact that no design and construction codes for highway widening project are available at present, the use of polyester fiberglass cloth to spliced seams of new and old semi-rigid base pavements of old roads or surface repairs of old asphalt concrete pavement or Crack treatment, which can effectively prevent the occurrence of reflective cracks and water damage, this polyester fiber cloth performance and construction process analysis.
