Abstract
THE PURPOSE OF THE PROPOSED RESEARCH IS TO EVALUATE THE FEASIBILITY OF RECYCLING EXISTING SEAL COAT PAVEMENTS THROUGH STABILIZATION WITH SELF CEMENTING FLY ASH. IT IS PROPOSED THAT THE EXISTING PAVEMENTS CAN BE PULVERIZED IN PLACE, SUFFICIENT QUANTITIES OF CLASS "C" FLY ASH AND WATER ADDED, AND THE RESULTING MIXTURE BE COMPACTED. THE STABILIZED SECTION COULD THEN BE UTILIZED AS A BASE COURSE SECTION HAVING SUPPORT CAPACITY THAN THE ORIGINAL MATERIALS. SELF CEMENTING FLY ASH IS CURRENTLY BEING USED TO STABILIZE SOILS AND GRANULAR BASE MATERIALS BY SIMILAR CONSTRUCTION OPERATIONS. THE PROPOSED RESEARCH IS INTENDED TO EVALUATE THE INFLUENCE OF THE ASPHALTIC BOUND PARTICLES IN THE STABILIZED MIXTURE. THE PHASE I PROGRAM WILL BE LIMITED TO A LABORATORY EVALUATION OF THE STABILIZED MIXTURE. THE INITIAL PHASE OF THE PROGRAM WILL ADDRESS INFLUENCE OF FLY ASH CONTENT, MOISTURE CONTENT AT TIME OF COMPACTION AND COMPACTIVE ENERGY ON THE STABILITY OF THE STABILIZED MIXTURE. THE FINAL PHASE WOULD ADDRESS THE ACCEPTABLE QUANTITIES AND OPTIMUM PARTICLE SIZE FOR THE ASPHALTIC BOUND PARTICLES AND INFLUENCE OF RETARDERS. THIS INFORMATION WILL PROVIDE A BASIS FOR ESTABLISHING CONSTRUCTION PROCEDURES AND MIX DESIGN CRITERIA FOR THE RECYCLED MATERIALS.
