PAVING MOTORWAYS WITH MODIFIED BITUMINOUS CONGLOMERATES: THE EXPERIENCES OF THE COMPANY AUTOVIE VENETE

PAVIMENTAZIONI AUTOSTRADALI CON CONGLOMERATI BITUMINOSI MODIFICATI: LE ESPERIENZE DELLA SOCIETA' AUTOVIE VENETE

SAFETY IS ASSOCIATED WITH THE VALUE OF ADHERENCE ON THE CONTACT SURFACE BETWEEN PNEUMATIC AND ROAD SURFACE, IN ANY CONDITION BUT ESPECIALLY ON WET ROADS. COMFORT IS ASSOCIATED WITH AN EVEN, ROAD SURFACE BOTH LONGITUDINALLY. THERE IS ANOTHER PARAMETER WHICH DESCRIBES THE CONDITIONS OF THE ROAD, INTENDED AS A PACKET OF THE BOUND LAYERS OF ASPHALT (OR EVENTUALLY CONCRETE), WHICH IS THE CARRYING STRUCTURE. A CORRECT ROAD DESIGN, AS FOR CORRECT MAINTENANCE, CANNOT OVERLOOK A CAREFUL EVALUATION OF THE IMPORTANCE TO ATTRIBUTE TO EACH PARAMETER INDICATED, IN RELATION TO THE IMPORTANCE OF THE ROAD, THE TRAFFIC CHARACTERISTICS OF THE ROAD AND THE SPEED OF THE ROAD. MAINTENANCE SHOULD INCLUDE NOT ONLY THE REPAIRS OF DAMAGE CAUSED BY THE AGGRESSIVE ACTION OF TRAFFIC, BUT ALSO AND ABOVE ALL THE ADAPTION OF THE STRUCTURAL AND FUNCTIONAL CHARACTERISTICS OF THE ROAD TO THE EVOLUTIONARY DYNAMIC OF THE TRAFFIC. IT IS THEREFORE IMPORTANT TO HAVE THE ADEQUATE MAINTENANCE TECHNIQUE AND APPROPRIATE MATERIALS AVAILABLE TO RESOLVE THE PROBLEMS, OF COURSE IN ADDITION TO HAVING FINANCIAL RESOURCES WHICH ALLOW FOR A VALID PROGRAMMING OF REPAIRS.
