TREATMENTS TO RETEXTURE A WORN CONCRETE SURFACE OF A HIGH- SPEED ROAD

EXPERIMENTS WERE CARRIED OUT ON A SECTION OF THE M.1 MOTORWAY TO DETERMINE THE MOST SUITABLE TREATMENT TO RESTORE ADEQUATE SKIDDING RESISTANCE TO A WORN CONCRETE SURFACE OF A HIGH-SPEED ROAD. MEASUREMENTS MADE DURING THE INITIAL THREE YEARS OF THE EXPERIMENT SHOWED THAT THE TREATMENTS HAD IMPROVED THE SIDEWAY-FORCE COEFFICIENT AT LOW SPEED (50 KM/H) AND THAT ALL THE TREATMENTS MARKEDLY REDUCED THE FALL IN SKIDDING RESISTANCE SHOWN BY THE UNTREATED SURFACE WHEN THE SPEED WAS INCREASED TO 130 KM/H. THE BEST OVERALL RESULTS WERE GIVEN BY A DIAMOND PATTERN OF NARROW GROOVES AND BY TRANSVERSE GROOVES. MEASUREMENTS WILL BE CONTINUED ON THE SECTIONS TO DETERMINE THE LONG-TERM EFFECT OF THE TREATMENTS. /AUTHOR/
