Research on Shrinkage Performance of Cement-Stabilized Macadam Base Adding Reclaimed Asphalt Mixture

Adding reclaimed asphalt mixture into cement-stabilized macadam base is a good way to save our resources, lower the construction cost and reduce environment pollution. This paper relies on the reconstruction and extension project for henan anxin expressway, adopts the low cement content and the skeleton dense aggregate gradation, analyzes the reclaimed asphalt mixture influence on the shrinkage performance of cement-stabilized macadam base. The test shows that reclaimed asphalt mixture can improve the shrinkage performance for roadbase when the roadbase satisfies strength requirement.
