Abstract


Currently, related specifications provide a wide grading range for cement stabilized aggregate and make it easy to meet. Evaluation of cement stabilized aggregate grading stays in qualitative evaluation: skeleton-void structure, suspension-dense structure, skeleton-dense structure. This paper proposed a new quantitative evaluation index for cement stabilized aggregate gradation. Experiments show that skeleton-dense value has good correlations with physical and mechanical properties. Contrast to CA value proposed by Bailey method, skeleton-dense value shows higher correlation coefficient with physical and mechanical properties.
