SELECTION OF MATERIALS FOR BASE AND SURFACE TREATMENTS

BITUMINOUS SURFACE TREATMENTS HAVE BEEN APPLIED SINCE 1923 TO 235 MILES OF SOUTH CAROLINA HIGHWAYS. THE OLD SURFACING MATERIAL WAS OF THREE TYPES: "TOP SOIL," WHICH IS TYPICALLY A VERY SMALL-SIZED GRAVEL WITH A SAND-CLAY MIXTURE AS BINDER AND OCCURRING IN DEPTHS OF 8--12 INCHES, CHIEFLY ON HILLS OR KNOLLS; "SAND CLAY," A NATURAL OR ARTIFICIAL MIXTURE OF SAND AND CLAY; AND "CLAY GRAVEL," A SURFACING THAT HAS FEW PEBBLES OVER 1/3 INCH IN DIAMETER AND THAT USES A SAND-CLAY MIXTURE AS BINDER. PRACTICES AND SPECIFICATIONS ARE DESCRIBED, AND CONCLUSIONS ARE DRAWN REGARDING THE TECHNIQUES TO BE USED.
