二灰碎石混合料抗裂配合比设计

On the anti cracking mixture ratio design of lime and flyash mixture

通过和现行规范中二灰级配碎石颗粒组成的对比,分析路面基层裂缝产生的原因,提出基于抗裂设计原则的二灰碎石混合料逐级填充的理想结构层次,给出既满足强度又具有较好抗裂性能的二灰碎石混合料配合比设计方法,并通过试验进行了验证。

Through the analysis of the lime and flyash mixture, discussion is made on the cases of cracking of highway course construction. It presents the mixture ratio design and construction technology, and proves to be feasible.
