Application study of recycled coarse aggregation on base course

Mechanism of action was analyzed for recycled coarse aggregation on the base course based on the engineering project of highway. The principle of physics and chemical action is clarified in the use of the recycled aggregation. Testing for key property of recycled coarse aggregation and the experiment of compression strength were operated and applied on basis of different matching recycled coarse aggregation and mixture of diverse admixture which are three kinds of cementing material. The result show that recycled coarse aggregation is accorded with requirement of highway base course when it is used of material of base course.
