A REVIEW OF THE LOW-SPEED SKIDDING RESISTANCE OF A NUMBER OF CONCRETE ROADS CONTAINING VARIOUS AGGREGATES

A REVIEW HAS BEEN MADE OF THE SIDEWAY FORCE COEFFICIENT AT 50 KM/H AND OF THE SKIDDING RESISTANCE VALUE OF 23 CONCRETE ROADS. THE CONCRETE MIXES USED CONTAINED NATURAL SANDS BUT A FEW OF THE SANDS HAD A HIGH LIMESTONE CONTENT. ONLY A FEW ROADS CONTAINED A COARSE LIMESTONE AGGREGATE AND ALL THESE ROADS WERE LIGHTLY TRAFFICKED. THE EFFECTS OF TRAFFIC INTENSITY, LIMESTONE CONTENT OF THE SAND, GRADING OF LIMESTONE COARSE AGGREGATE, DEGREE OF STONE EXPOSURE AND EFFECT OF THE MIX PROPORTIONS ARE DISCUSSED. IT IS CONCLUDED THAT FOR HEAVILY TRAFFICKED ROADS, CARE IS NECESSARY IN THE USE OF SANDS CONTAINING A PROPORTION OF LIMESTONE AND IN THE CHOICE OF THE GRADING OF LIMESTONE COARSE AGGREGATE. RECOMMENDATIONS ARE MADE FOR FURTHER WORK. /RRL(A)/
