VOIDS CONCEPT FOR DESIGN OF SEAL COATS AND SURFACE TREATMENTS-WITH DISCUSSION

A SURFACE TREATMENT DESIGN PROCEDURE BASED ON THE MEASURED VOIDS CONTENT OF AN AGGREGATE LAYER IS PRESENTED. THE PROCEDURE CAN BE USED FOR THE DESIGN OF SINGLE-APPLICATION SURFACE TREATMENTS AND SEAL COATS. RELATIONSHIPS ARE DEVELOPED FOR THE QUANTITIES OF COVER AGGREGATE AND ASPHALT BINDER REQUIRED TO PRODUCE SURFACE TREATMENTS THAT SHOULD EXHIBIT GOOD PERFORMANCE CHARACTERISTICS IN THE FIELD. FACTORS TAKEN INTO ACCOUNT IN THE DETERMINATION OF THESE QUANTITIES INCLUDE AGGREGATE SIZE, AGGREGATE SHAPE, AGGREGATE SOURCE, AGGREGATE QUANTITY, AGGREGATE FINES, PERCENTAGE OF SOLVENT IN BINDER, HARDNESS OF UNDERLYING SURFACE, EMBEDMENT OF AGGREGATE INTO THE UNDERLYING SURFACE TEMPERATURE, AND COMPACTIVE EFFORT. A DESIGN EXAMPLE IS ALSO PRESENTED TO ILLUSTRATE THE USE OF THE METHOD AND THE PRINCIPLES IT INCORPORATES. /AUTHOR/
