摘要
通平高速公路沿线广泛分布的风化花岗岩填料因具有遇水易散、结构松散、水稳性差、粘结力小等特点,施工碾压成型困难。本研究通过现场填料调查、试验分析得到了填料特征,通过修建试验路对压实工艺及与压实遍数的关系开展了试验,得出风化花岗岩残积土适宜的压实遍数、现场填筑含水量等的要求。
The widely distributed weathered granite residual soil in Tongping Expressway was difficult to compact because of its water fugitive,loose structure,bad water stability and mall cohesive force.This packing characteristics was studyed through the field filler surveys and test analysis,the test of the relationship between compaction process and compaction times was carryed out by the construction of the test road.The appropriate compaction time and site reclaimed water content and others requirements of weathered granite residual soil were obtained.
