摘要
路基土回弹模量对路面设计具有重要意义。采用水泥砂作为路基处治土,通过室内回弹模量试验,基于试验数据,建立水泥砂的回弹模量与压实度、水泥含量的预估方程,为其回弹模量的预估提供参考方法。通过室内试验进行验证,结果表明:实测值与预估值较好吻合。
Resilient module of subgrade soil is significant to the pavement design. Based on laboratory results, an equation is developed to predict the resilient module of the sand-cement which is used as stabilized soil. The results of laboratory tests indicate that the predicted values are in good agreement with measured results.
