基于不同骨架结构的水泥稳定碎石抗收缩性能研究

Research on anti shrinkage performance of cement stabilized macadam based on different skeleton structure

高寒地区昼夜温差大、冬季气温低,水泥稳定碎石基层易产生收缩性裂缝。本文针对不同骨架结构的水泥稳定碎石材料进行干缩和温缩试验,评价不同水泥掺量下骨架密实型和骨架悬浮型水泥稳定碎材料的抗收缩性能。

The temperature difference between day and night in the cold area is large,and the temperature is low in winter. The cement stabilized macadam base is easy to produce shrinkage crack. In this paper,the dry shrinkage and temperature shrinkage tests of cement stabilized macadam materials with different skeleton structure are carried out to evaluate the anti shrinkage performance of skeleton dense type and skeleton suspension type cement stabilized crushed materials with different cement content.
