A GENERAL METHOD OF DESIGN FOR SEAL COATS AND SURFACE TREATMENTS

THE PRINCIPAL OBJECTIVE OF THIS PAPER IS TO DEMONSTRATE THAT ONE EQUATION FOR THE QUANTITY OF COVER AGGREGATE REQUIRED AND ANOTHER EQUATION FOR THE QUANTITY OF ASPHALT BINDER TO BE APPLIED, CAN BE USED FOR THE DESIGN OF EITHER SINGLE APPLICATION OR MULTIPLE APPLICATION SURFACE TREATMENTS AND SEAL COATS. THE REQUIRED CHARACTERISTICS OF BOTH COVER AGGREGATES AND ASPHALT BINDERS ARE REVIEWED. THE SUPERIORITY OF ONE-SIZE OVER GRADED COVER AGGREGATES IS DEMONSTRATED. EQUATIONS ARE DEVELOPED FOR THE QUANTITIES OF COVER AGGREGATE AND ASPHALT BINDER REQUIRED FOR SINGLE APPLICATION SURFACE TREATMENTS AND SEAL COATS. A SAMPLE CALCULATION ILLUSTRATES THEIR USE FOR THIS PURPOSE. IT IS SHOWN THAT THESE SAME EQUATIONS CAN BE EMPLOYED FOR THE DESIGN OF MULTIPLE SEAL COATS AND SURFACE TREATMENTS. SAMPLE CALCULATIONS ARE INCLUDED TO ILLUSTRATE THEIR USE IN THIS RESPECT. THE PRINCIPLES OF CONSTRUCTION FOR SINGLE AND MULTIPLE APPLICATION SURFACE TREATMENTS AND SEAL COATS ARE REVIEWED. /AUTHOR/
