摘要
水泥稳定砂砾半刚性基层材料在我省高速公路建设中得到了普遍运用 ,有许多成熟的经验 ,丹本高速公路路面一、二标段路面基层便采用了这种材料 ,但由于沿线河流砂砾较粗 ,细料含量少 ,施工和易性差 ,压实度难已保证 ,通过添加适量粉煤灰 ,既有利于碾压密实 ,又提高了路面基层的强度 ,一举两得 。
Cement-stabilized gravel semi-rigid base material was used on Danben Expressway Pavement.But because the gravel was think,fine gravel was little,the construction workability was worse and compactness was difficult to ensure.By adding right amount fly ash,the compacting was tighter and the base was more strength.
