POLISHING TEST ON CHIPPINGS - STATE OF THE ART AND GROUP ANALYSIS

项目名称：	POLISHING TEST ON CHIPPINGS - STATE OF THE ART AND GROUP ANALYSIS
摘要：	FOR REASONS OF SAFETY THE SKIDDING RESISTANCE OF ROAD SURFACINGS IS PARTICULARLY IMPORTANT. TOGETHER WITH OPTIMUM COMPOSITION OF THE MIXTURE, THE POLISHING OF STONE AGGREGATES IS OF GREAT IMPORTANCE FOR THE LONG-TERM SKIDDING RESISTANCE OF SURFACINGS. GROUP ANALYSES ON SELECTED SAMPLES OF REFINED CHIPPINGS ARE TO BE UNDERTAKEN TOGETHER WITH COMPREHENSIVE SERIES OF TESTS. THE AIM IS TO CLARIFY (1) THE MAGNITUDE OF TESTING ERRORS ASSOCIATED WITH THE USE OF THE NEW GUIDELINES FOR CARRYING OUT POLISHING TESTS ON CHIPPINGS; (2) THE QUALITIES OF ROCK AVAILABLE IN INDIVIDUAL FEDERAL STATES; (3) THE FLUCTUATIONS IN THE RESULTS OF TESTS ON MATERIAL FROM ONE QUARRY; (4) WHETHER COMPARATIVE ENGLISH GRAVEL (ENDERBY QUARRY) CAN BE REPLACED BY AUSTRIAN STANDARD GRANITE.
