ELECTRICAL ROAD DE-ICING ON THE "PASS LUEG" CROSSING OF THE SALZACH (TAUERN MOTORWAY)

ELEKTRISCHE FAHRBAHNENTEISUNG BEI DER SALZACHQUERUNG "PASS LUEG" (TAUERNAUTOBAHN)

FOR THE FIRST TIME IN THE CONSTRUCTION OF THE AUSTRIAN MOTORWAY SYSTEM, 1974 SAW THE INSTALLATION OF A SUBSTANTIAL LENGTH OF DE-ICING EQUIPMENT IN THE VICINITY OF PASS LUEG. THE PARTICULAR TOPOGRAPHIC CONDITIONS AS WELL AS GOOD TECHNICAL PROVISIONS HAVE FAVOURED THE INSTALLATION HERE OF A CARRIAGEWAY HEATING SYSTEM. THE HEATED MOTORWAY SECTION INCLUDES THE 115 M LONG SALZACH BRIDGE, THE ADJACENT EMBANKMENT LENGTHS AND THE ENTRANCE ZONES TO BOTH THE ADJOINING TUNNELS. THE TOTAL LENGTH IS 426 M, THE MAXIMUM LOAD REQUIREMENTS REACH 860 KW, THE OPERATING VOLTAGE OF THE HEATING SYSTEM IS THE NORMAL NETWORK VOLTAGE OF 380 VOLTS. THE WET-ON-WET INSTALLATION OF THE HEATING CABLE LOOPS IN THE FORM OF PRE-FABRICATED HEATING MATS OF CORRECT SIZE FOLLOWED CLOSELY BEHIND THE FULLY MECHANISED CONSTRUCTION OF THE CONCRETE CARRIAGEWAY DECK WITHOUT DELAY TO THE BUILDING PROCESS. THE CONTROL AND ADJUSTMENT IS ACHIEVED BY MEANS OF A SPECIALLY MODIFIED PROCESS COMPUTER. WITH THIS DYNAMIC CONTROL IT IS POSSIBLE TO ENSURE THE OPERATION OF THE INSTALLATION AT THE APPROPRIATE TIME IN SELECTED ZONES ACCORDING TO PRIORITIES AND PROVIDE FOR THE OPTIMUM FUNCTIONING OF THE SYSTEM WITH MINIMUM ENERGY USE.
