HIGHWAY MAINTENANCE HIGHLIGHTS

SOME AGGRESSIVE MAINTENANCE PROGRAMS ARE DESCRIBED IN NEW YORK STATE. TWO METHODS OF SHOULDER MAINTENANCE SURFACE TREATMENTS ARE DESCRIBED. THE FIRST METHOD INVOLVES BACKING A STONE TRUCK OVER FRESHLY APPLIED TAR, AND THE SECOND INVOLVES THE USE OF A BIT FORWARD PAVER WHICH IS A COMBINATION DISTRIBUTOR AND CHIP SPREADER WHICH MOVES FORWARD DURING THE ENTIRE OPERATION. THIS IS ACCOMPLISHED BY APPLYING BOTH TAR AND STONE IN THAT ORDER FROM THE FRONT OF THE VEHICLE. A NEW BIT FORWARD PAVER WAS DEVELOPED AND MANUFACTURED BY THE AKRON CONTRACTORS EQUIPMENT COMPANY WHICH CONSISTS OF A TRACTOR TYPE UNIT WITH STONE BOX AND SPRAY BAR AT ITS FRONT AND A CONVENTIONAL TRACTOR FIFTH WHEEL AT ITS REAR. THE FIFTH WHEEL IS MOVEABLE AND CAN TRAVEL 9 INCHES TRANSVERSELY IN EITHER DIRECTION TO SPEED HOOKUPS WITH RECHARGED TRANSPORTS. THE NEW BIT PAVER HAS PROVEN ECONOMICAL. NEW PAVING MARKING EQUIPMENT, THE NITELINER, DEVELOPED BY WALD, WAS APPLIED. THESE MACHINES ARE EQUIPPED WITH A HYDRAULICALLY OPERATED LEFT AND RIGHT OUTRIGGER WITH A MAXIMUM REACH OF 14 FEET. TWO COLORS OR A MAXIMUM OF FOUR LINES MAY BE APPLIED SIMULTANEOUSLY. THE UNITS APPLY A SPECIAL HIGH VISCOSITY PAINT THAT CAN BE USED ANYTIME, PROVIDED THE PAVEMENT IS DRY AND THE TEMPERATURE IS ABOVE FREEZING. THE PAINT AND THE MACHINES ARE EXPENSIVE BUT DEFINITE SAVINGS IN MONEY, TIME AND IMPROVEMENTS IN OPERATIONAL EFFICIENCY HAVE BEEN DEMONSTRATED. EXPERIMENTS HAVE BEEN CONDUCTED ON CARBIDE TIPPED BLADES MOUNTED ON ONE- WAY PLOWS CARRIED BY 5 TON TRUCKS. EXPERIMENTAL RESULTS INDICATE ANNUAL SAVINGS FOR ONE COMPLETE SNOW AND ICE CONTROL PERIOD WILL BE APPROXIMATELY $52,000. EXPERIMENTS ARE PLANNED WITH CARBIDE TIPPED BLADES ON REVERSIBLE PLOWS AND WINGS.
