| Abstract: | Skeleton-closed cement stabilized crush stone mixture contain more coarse aggregate, and more segregation phenomena appear during construction. After analyzing the reason which causes segregation, the paper presents some methods to improve these phenomena from several aspects such as mixture design, mixture blend, transportation and mixture paving. At the same time, a test method is given to assess mixture segregation extent for different construction stage. |
