BITUMINOUS WEARING COURSES, ROAD MAINTENANCE 2

BITUMINOESE DECKSCHICHTEN, STRASSENINSTANDHALTUNG 2

WITHIN THE FRAMEWORK OF ROAD SAFETY THE MOST IMPORTANT TASKS OF ROAD MAINTENANCE INCLUDE EXPERT REPAIR AND MAINTENANCE OF BITUMINOUS WEARING SURFACES BY MEANS OF PATCHING, PORE CLOSING, REPEATED SURFACE TREATMENT AND THIN WEARING COURSES. A PREREQUISITE FOR PLANNING, ORGANISATION, EXECUTION AND CALCULATION OF MEASURES FOR FULL UTILIZATION OF ROADS IS THE ANNUAL ASSESSMENT OF THE STATE OF ROAD REPAIR AND THE ANNUAL REQUIREMENTS IN A CYCLIC SYSTEM. ACCORDING TO THE STATE OF THE SURFACING AND THE DEGREE OF EVENNESS EACH ROAD SECTION IS CLASSIFIED BY GRADING IT FROM 1 TO 4. DEPENDING ON THE BITUMINOUS TYPE OF SURFACING AND ITS STATE OF REPAIR, THE ROAD CHARACTERISTICS AND TRAFFIC VOLUME, THE CLASSIFICATION IS REPEATED IN CERTAIN SECTIONS - THE CYCLES. BASED ON YEARS OF EXPERIENCE NORMAL WEAR PERIODS ARE QUOTED DEPENDING ON THE TRAFFIC VOLUME OF BITUMEN STABILISED ROADS, E.G. ROLLED ASPHALT 8 TO 12 YEARS. SO CALLED SERVICE AND MODEL TECHNOLOGIES WITH ECONOMICAL LIFE TIME FACTORS ARE THE BASIS FOR OPTIMISING MAINTENANCE METHODS FOR MAINTAINING THE USEFULNESS OF WEARING COURSES. AT THE MOMENT THERE IS NEED FOR ONE MAN FOR EVERY 7 TO 10 KM OF ROAD. DETAILED DESCRIPTIONS ARE GIVEN OF THE TECHNICAL METHODS WITH MATERIAL COMPOSITIONS AND MATERIAL QUANTITIES AND THE EQUIPMENT AND PLANT EMPLOYED. WITH THE AID OF MEASURING STANDARDS THE QUALITY OF COMPLETED MAINTENANCE WORK IS RATED BETWEEN 1 AND 4.
