Abstract:

STUDIES CONDUCTED AT WEST VIRGINIA UNIVERSITY HAVE SHOWN THAT THE ENGINEERING PROPERTIES OF BOTTOM ASH ARE COMPARABLE TO THOSE OF CONVENTIONAL CONSTRUCTION MATERIALS. NEVERTHELESS, BOTTOM ASH AND FLY ASH HAVE NOT BEEN WIDELY USED IN HIGHWAY CONSTRUCTION IN THE UNITED STATES. DURING THE PAST 3 YEARS, CONSIDERABLE EXPERIENCE HAS BEEN GAINED IN WEST VIRGINIA AND THE SURROUNDING STATES IN THE UTILIZATION OF COAL ASH IN HIGHWAY CONSTRUCTION. THE APPLICATIONS HAVE INCLUDED USE OF BOTTOM ASH OR FLY ASH OR BOTH IN NONSTABILIZED BASE COURSES, PORTLAND CEMENT AND BITUMINOUS STABILIZED BASE COURSES, BITUMINOUS SURFACE COURSES, LIGHTWEIGHT STRUCTURAL FILL, AND UNDERDRAIN FILTERS. IT WAS FOUND THAT ASH MATERIALS CAN BE USED STATISFACTORILY IN THESE APPLICATIONS PROVIDING THEIR UNIQUE PROPERTIES ARE RECOGNIZED AND APPROPRIATE CONSTRUCTION TECHNIQUES ARE EMPLOYED. IT IS SHOWN THAT THESE MATERIALS DO NOT ALWAYS FIT WITHIN THE FRAMEWORK OF EXISTING MATERIALS AND CONSTRUCTION SPECIFICATIONS AND THAT ADHERENCE TO THESE SPECIFICATIONS DOES NOT ALWAYS ENSURE SATISFACTORY PERFORMANCE. IN FACT, IN SOME INSTANCES BETTER PERFORMANCE AND GREATER ECONOMY WERE ACHIEVED WITH ASH MIXTURES THAT DID NOT MEET EXISTING SPECIFICATIONS. IF ASH IS TO BE USED EFFECTIVELY IN HIGHWAY CONSTRUCTION, NEW SPECIFICATIONS MUST BE DEVELOPED THAT TAKE INTO CONSIDERATION THE UNUSUAL PROPERTIES OF ASH AND THE SPECIALIZED CONSTRUCTION TECHNIQUES REQUIRED.
