二灰碎石半刚性基层裂缝成因与防治研究

Research on Reasons for Cracks of Lime-Fly Ash Macadam Semi-Rigidity Base and Prevention-Treatment of Them

通过分析二灰碎石强度形成的机理,重点讨论了二灰碎石半刚性基层裂缝的类型以及二灰碎石半刚性基层裂缝产生的原因,立足于二灰碎石半刚性基层从原材料、配合比设计以及施工方面上提出了裂缝的防治措施,对工程技术人员提供借鉴参考。

Through the medium of analysis of mechanism for forming of lime - fly ash - macadam strength, discussion eentres on the types and causes for the base crack. The paper puts forward measures for cracks prevention - treatment from raw and processed materials, proportioning design and construction, which can provide use and reference for engineers and technicians.
