近几年来,国外已广泛利用无机结合料水泥来稳定砂及砂砾石材料,作柔性路面基层,取得了良好的效果。国内北京、上海、广东等省、市采用水泥稳定结构作路面基层的实践证明,这种半刚性路面基层材料,具有优良的路用技术性能和经济效果。水泥剂量仅4～6(重量比)28天抗压强度可达到30kg/cm~2以上。比石灰土28天强度高3～4倍,造价和石灰土基本相同。
In recent years, foreign countries have made extensive use of inorganic binder cement to stabilize the sand and gravel materials for grassroots grassroots flexible, and achieved good results. Domestic Beijing, Shanghai, Guangdong and other provinces and municipalities using cement stabilized structure as the grassroots grassroots practice has proved that this semi-rigid pavement base material, with excellent road technical performance and economic results. Cement dosage of only 4 to 6 (weight ratio) 28 days compressive strength up to 30kg / cm ~ 2 or more. 28 days higher than the lime soil strength 3 to 4 times, cost and lime soil is basically the same.
