STUDY OF ROAD FRICTION

ADMIXTURE OF GROUND GLASS, IN AN AMOUNT OF 10 PERCENT TO 30 PERCENT, TO ASPHALTIC WEARING COURSES OF ROAD PAVEMENTS MADE WITH LIMESTONE OR DOLOMITIC AGGREGATES, PERMITTED CONSIDERABLE IMPROVEMENT OF THEIR WET SKID RESISTANCE. IN ADDITION, THIS ADMIXTURE PARTIALLY COUNTERACTED THE EFFECT OF SURFACE WEAR, WHICH HAD REDUCED THE ORIGINAL RESISTANCE TO A DANGEROUSLY LOW LEVEL. FROM THE VIEWPOINT OF SKID RESISTANCE, PURE 8/100 BITUMEN IS APPARENTLY THE BEST COMPARED WITH THE OTHER VARIANTS TESTED (40/50, 60/70, PURE AND MIXED WITH KEROSENE; ALSO, 80/100 MIXED WITH KEROSENE). CONSIDERING THE PROHIBITIVE COST OF BASALTIC AND GRANITE AGGREGATE (USEFUL IN PAVING MIXTURES FROM THE FRICTION VIEWPOINT), AND THE ADDITIONAL EXPENSE INVOLVED IN THEIR TRANSPORTATION TO THE MAIN SITES OF ROAD CONSTRRUCTION, THE POTENTIALITIES OF GROUND GLASS AS AGGREGATE SHOULD BE GIVEN SERIOUS CONSIDERATION, INCIDENTALLY ALSO PROVIDING A SOLUTION TO THE DISAGREEABLE PROBLEM OF DOMESTIC GLASS WASTE. /AUTHOR/
