STUDY OF THE USE AND ADAPTATION OF HOT ROLLED ASPHALT IN AUSTRIAN CONDITIONS WITH RESPECT TO RAW MATERIAL, CLIMATE AND TRAFFIC

UNTERSUCHUNG DER ANWENDUNG UND ADAPTIERUNG DES HOT ROLLED ASPHALTS UNTER DEN IN OESTERREICH GEGEBENEN BEDINGUNGEN HINSICHTLICH ROHSTOFF, KLIMA UND VERKEHR

A STUDY IS TO BE MADE OF THE SUITABILITY OF HOT ROLLED ASPHALT FOR AUSTRIAN CONDITIONS. FOUR DESIGNS ARE TO BE EXAMINED: LOW CHIPPINGS CONTENT, LOW CHIPPINGS CONTENT WITH TRINIDAD EPURE, HIGH CHIPPINGS CONTENT, AND HIGH CHIPPINGS CONTENT WITH TRINIDAD EPURE. TWO EXPERIMENTAL SECTIONS OF ROAD ARE TO BE USED, ONE IN THE MOUNTAINS AND ONE IN THE LOWLANDS. INCORPORATION WILL BE UNDER NON-DESTRUCTIVE CONTROL, AND AFTER LAYING FURTHER STUDIES WILL BE MADE: SAMPLING, NON-DESTRUCTIVE MEASUREMENT OF DENSITY AND THICKNESS, SURFACE PROPERTIES (PHOTOGRAPHIC DOCUMENTATION, DEPTH OF ROUGHNESS, EVENNESS, SKIDDING RESISTANCE). EVALUATION OF THE RESULTS OF MEASUREMENTS AND OBSERVATIONS WILL TAKE PLACE AFTER THE MATERIAL HAS BEEN DOWN FOR FOUR YEARS.
