华南多雨地区倒装结构级配碎石防水研究

Research on Anti-drainage of Inverted Structure Graded Crushed Stone in Rainy Area of South China

级配碎石过渡层含水率过大,将会影响到结构层整体强度。通过对广河高速惠州段施工过程弯沉数据分析,研究降水对级配碎石过渡层施工工艺的影响,结合仁博高速新博段级配碎石过渡层上封层试验段,提出级配碎石过渡层上封层防水施工工艺及要求,为国内外同行提供一些有益借鉴和参考。

If the moisture content of transition layer of graded crushed stone is too high,it will affect the overall strength of the structural layer. By means of analysis of deflection data during construction in Guanghe(Huizhou) highway,to study the influence of precipitation on the construction technology of graded crushed stone transition layer. Combine with the test road of upper seal coat of graded crushed stone transition layer in Renbo(Xinbo) highway,put forward waterproof construction technology and requirements of upper seal coat of graded crushed stone transition layer, to provide some beneficial reference and reference for domestic and foreign counterparts.
