MERITS AND ECONOMICS OF PREHABRICATED TYPES OF HIGHWAY-RAILWAY GRADE CROSSINGS
THIS REPORT WAS PRESENTED IN TOW PARTS. PART I REPORTS AN INSPECTION MADE OF CONCRETE SLAB CROSSINGS OF A EUROPEAN DESIGN. THE MODIFICATIONS AND ADVANTAGES OF THIS TYPE OF CROSSING AS USED IN THE U.S. ARE DISCUSSED. IN PART II FOURTEEN HIGHWAY GRADE CROSSINGS, CONSISTING OF STEEL-REINFORCED RUBBER SURFACE PADS SUPPORTED BY WOODEN SHIMS ON TOP OF THE CROSS TIES, WERE EVALUATED. IT WAS NOTED THAT SOME IMPROVEMENTS IN THE DESIGN AND MANUFACTURE OF THE CROSSINGS WERE MADE AFTER THE EARLIEST INSTALLATIONS (INSTALLATION DATA RANGE, 1955-1961). THE SHORTEST SERVICE LIFE WAS A CROSSING WHICH REQUIRED REPLACEMENT AFTER SIX YEARS. FOLLOWING THIS WERE THREE CROSSINGS WHICH HAD ACTUAL OR PROJECTED TOTAL SERVICE LIVES OF 14 OR 15 YEARS. SEVEN, OR 50 PERCENT, OF THE CROSSINGS, HAD PROJECTED LIVES OF 21 YEARS OR LESS. ON THE OTHER HAND, FIVE, OR ABOUT 36 PERCENT, HAD LIVES ESTIMATED AT GREATER THAN 35 YEARS OR INDEFINITE. WHERE MAINTENANCE COSTS WERE AVAILABLE (NINE CROSSINGS), THEY RANGED FROM NO REPORTED MAINTENANCE IN 10 OR MORE YEARS TO 185 DOLLARS PER YEAR (NOT INCLUDING REPLACEMENT).
