THE PRACTICAL APPLICATION OF THE DESIGN METHOD OF ASPHALTIC MIXTURES TO PAVEMENT CONSTRUCTION

THE SOLUTIONS TO THE FOLLOWING PROBLEMS ARE DISCUSSED: (1) ARE AGGREGATE MATERIALS WHICH ARE LOCALLY AVAILABLE SUITABLE FOR USE IN ASPHALT PAVEMENTS; (2) IF TWO OR MORE AGGREGATES ARE TO BE BLENDED, WHAT ARE THE DESIRABLE PROPORTIONS FOR EACH; (3) WHAT PERCENT ASPHALT IN THE PAVING MIXTURE SHOULD BE USED AS A BASIS OF ESTIMATE FOR TOTAL QUANTITIES REQUIRED; AND (4) IS THE ASPHALT MIXTURE AS PRODUCED AND LAID AS A PAVEMENT OF SATISFACTORY QUALITY, CONTAINING THE PROPER AMOUNT OF ASPHALT FOR THE MAXIMUM INTENDED SERVICE? ITEMS 1, 2, AND 3 INVOLVE PRELIMINARY DESIGN WORK AND SHOULD BE COMPLETED WELL IN ADVANCE OF ACTUAL CONSTRUCTION. ITEM 4 INCLUDES A FINAL DESIGN BASED ON MATERIALS ACTUALLY TAKEN FROM PLANT BINS AND INCLUDES CONSTANT SAMPLING, TESTING, AND ANALYSIS OF THE ASPHALT MIXTURE AS IT IS BEING PRODUCED. /AUTHOR/
