摘要
鉴于粉土路基的特性,对低液限粉土路基碾压施工进行技术分析。在实际工程中对低液限粉土路基进行现场碾压试验,得到低液限粉土的最大干密度、最大含水量、现场碾压含水量等数据以及压实度、碾压沉降的测试结果,证明采用14t压路机压实粉土路基时松铺厚度不宜超过30cm,且每层填土压实5~6遍最佳。
Technical analysis on the compaction technology for low liquid limit silt subgrade was carried out based on its characteristics.Site test on low liquid limit silt subgrade was conducted in actual project,and the maximum dry density,maximum water content and compaction water content of low liquid limit silt and the compaction degree and settlement were obtained.It is proven that the lay-down thickness should not exceed 30 cm when compacting with 14 trollers,and 5or 6times of compaction produces the best result.
