POLISHING STONE VALUES OF NOVA SCOTIA ROAD SURFACING AGGREGATES

THE POLISHED STONE VALUES OF THIRTY AGGREGATE SAMPLES FROM DIFFERENT PARTS OF NOVA SCOTIA ARE DETERMINED. THE PROCEDURE FOLLOWED FOR THE STUDY CONSISTS OF POLISHING THE AGGREGATES IN AN ACCELERATED POLISHING MACHINE AND THEN TESTING THEM FOR THEIR FRICTIONAL PROPERTIES IN A BRITISH PORTABLE SKID TESTER. THE RESULTS ARE COMPARED WITH THE STANDARDS FIXED BY THE ROAD RESEARCH LABORATORY, ENGLAND, AND A CLASSIFICATION FOR RATING NOVA SCOTIA AGGREGATES IS SUGGESTED. THE RESULTS INDICATE THAT THE POLISHED STONE VALUES OF ABOUT 83% OF THE AGGREGATES TESTED LIE BETWEEN 48 & 58 AND THE REMAINING 17% BETWEEN 59 & 61. AN EFFORT IS MADE TO ESTABLISH CORRELATION BETWEEN THE POLISHED STONE VALUES AND OTHER FREQUENTLY USED PHYSICAL PROPERTIES OF ROAD AGGREGATES SUCH AS THE LOS ANGELES ABRASION LOSS AND THE PETROGRAPHIC NUMBER. HOWEVER, NO SIGNIFICANT RESULTS ARE OBTAINED FOR ANY MEANINGFUL CORRELATION. /RATAOC/
