摘要
利用单粒级和连续级配的两种集料配制石灰-粉煤灰碎石.在不同集料情况下,分析比较两种石灰-粉煤灰碎石强度的形成以及强度和模量的发展规律,并就几种路面基层材料的耐久性进行对比试验,认为石灰-粉煤灰碎石具有较好的耐久性能,采用连续级配集料配制的石灰-粉煤灰碎石具有较优的力学和耐久性能.
Two kinds of lime-flyash treated aggregate (LFA) are produced byusing open-graded and dense graded aggregates respectively. The differences inthe strength-creating principle and the development laws of strength and mod-ulus of these two LFAs are investigated. Moreover, tests on the duabilityproperties of several kinds of roadbase materials are performed. It is found that theLFA has good duability property, and the dense graded aggregate LFA has bettermechanics and duability properties than the open graded aggregate LFA.
