| Abstract: | In order to reduce the blindness and the bill quantities of a large number of orthogonal tests which are applied in the voidage design of existing open-graded concrete,it proposes theoretical design method of voidage of open-graded concrete via combining theoretical analysis and experimental verification.Experimental results show that the design method can correctly guide the design of a voidage and mixture ratio of open-graded concrete,which has important theoretical significance and engineering application value. |
