THE EXTENSION OF PAVEMENT LIFE BY MEANS OF THIN ASPHALTIC CEMENT PLANT MIX-MACHINE PLACED OVERLAYS AND COMPARISON BETWEEN STANDARD MIXES AND MIXES CONTAINING ASBESTOS FIBRES

SURFACE OVERLAYS CAN ECONOMICALLY ACCOMPLISH TWO BASIC NEEDS' /1/ RESTORE A SMOOTH WEARING SURFACE TO OLD PAVEMENTS AND /2/ UPGRADE OLDER MARGINAL BASED ROADS TO HANDLE HEAVIER TRAFFIC. THESE RESULTS CAN BE ACCOMPLISHED WITH STANDARD CONVENTIONAL MIXES OR ASBESTOS FIBRE MIXES. IT IS POSSIBLE THAT THE USE OF LOWER PLACEMENT TEMPERATURES AND IMPROVED ROLLING PROCEDURE COULD MATERIALLY IMPROVE THE RELATIVE MERITS OF STANDARD MIXES TO ASBESTOS MIXES. A COST ANALYSIS IS GIVEN. DATA FOR THIS REPORT IS NOT COMPLETE AND CONCERN IS EXPRESSED REGARDING INCONSISTENT LABORATORY FIELD CORE RESULTS AND AIR VOID RELATIONSHIPS. ALTHOUGH IT IS NOT BELIEVED THAT FOUR YEARS IS SUFFICIENT TIME TO COMPLETELY EVALUATE THE END RESULTS OF THE PROGRAM, IT DOES APPEAR THAT ASBESTOS FIBRE ADMIXTURES DO PROVIDE SOME OF THE ANSWERS.
