水泥稳定石屑基层的施工

Layout of Solid Cement-gravel Road-bed

水泥稳定石屑基层属于半刚性基层。它具有良好的力学性、板结性。它的初期强度较高,并且随龄期增长。它的水泥稳定性和温缩性比其它材料要好。此文结合工程实际介绍道路水泥稳定石屑基层施工工艺,重点介绍了它的施工上的控制包括它的配合比、拌和、运输、摊铺、压实、养生等工作。

Solid cement-gravel roadbed is sort of semi-rigidity bed that gives good performance in mechanics and hardening. The bed provides better early - stage strength and will gain more strength as time goes by. It has better cement stability and contract than other materials. This article introduces the techniques from practical experience in laying the bed, focusing on the technical control in process, including formula, mixing and stir, transportation, spreading-out, ramming, and maintenance.
