VIRGINIA'S EXPERIENCE WITH A QUALITY ASSURANCE AND ACCEPTANCE SPECIFICATION FOR ASPHALTIC CONCRETE

THE VIRGINIA DEPARTMENT OF HIGHWAYS HAS USED A STATISTICAL QUALITY ASSURANCE AND ACCEPTANCE SPECIFICATION FOR ASPHALTIC CONCRETE PRODUCTION SINCE 1968. DURING THIS PERIOD, NEARLY 3 MILLION TONS OF PLANT MIX HAVE BEEN BROUGHT UNDER THIS SPECIFICATION. THE MAJOR BENEFITS DERIVED FROM USE OF THE SPECIFICATION INCLUDE A CLEAR-CUT UNDERSTANDING BETWEEN THE PRODUCER AND THE STATE AS TO CONTROL AND ACCEPTANCE RESPONSIBILITIES. ALSO, A LARGE DECREASE IN ACCEPTANCE TESTING WITH NO CHANGE IN QUALITY HAS OCCURRED. SOME ASPECTS OF THE SPECIFICATION, HOWEVER, COULD BE IMPROVED BY SLIGHT MODIFICATIONS. IT HAS BEEN NOTED THAT VARIABILITY DOES NOT DECREASE WITH DURATION OF PLANT OPERATION. /AUTHOR/
