1, the cement dosage of cement stabilized soil base should not exceed 6%.
2, cement stabilized soil base construction, flow operation method must be adopted, so that each process closely linked. In particular, the delay time between mixing and rolling should be as short as possible.
3. In the process of cement stabilized soil base construction, the influence of delay time of cement stabilized soil on its strength should be tested to guide the construction and ensure that unqualified mixture is not used in the project.
4. In the process of cement stabilized soil base construction, it is necessary to comprehensively consider the requirements of cement final setting time on construction transportation vehicles, transportation distance and paving and rolling time, and add retarder when necessary to ensure the smooth construction.
5, cement stabilized soil base layer construction, the second layer must be in the first layer of health for 7 days before paving. Before laying the second layer, sprinkle a small amount of cement or grout on the top surface of the first layer.
6, lime stabilized soil base, lime industrial waste residue stabilized soil base, layered construction, the lower lime stabilized soil rolling is completed, you can immediately spread a layer of lime stabilized soil, do not need a special curing period.
7, inorganic binder base construction should be organized in late spring and high temperature season, the daily minimum temperature during construction should be above 5℃, in frozen areas, should be completed half a month to one month before the first heavy freezing (-5 ~-3℃).
