不掺结合料水泥稳定碎石基层就地冷再生混合料试验研究

Experiment for Cold In-Place Recycling Mixture of Cement Stabilized Macadam Base Without Binder

选取四种不掺结合料的水泥稳定碎石基层冷再生混合料,分别对其进行回弹模量、CBR、直剪、劈裂强度等试验,比较不同混合料的使用性能情况,引入贝雷法的级配骨架性判定方法对上述四种级配混合料的骨架形成情况进行评价,并作为最终推介不掺结合料水泥稳定碎石基层冷再生集料级配的依据之一。

Four kinds of cold recycling mixture of cement stabilized macadam base without binder are chosen to test their modulus of resilience,CBR,direct shear and cleavage strength,the service performance of each kind of mixture are compared.The Bailey judging method is introduced to evaluate the skeleton formation situation of these gradation mixtures,which is taken as the basis for recommending the cold recycling mixture of cement stabilized macadam base without binder.
