Tandem drive and tandem trailer axles are limited to 34,000-lbs each. Legal weight limits for state highways must be cautiously observed. If necessary, the vehicle weight will be adjusted accordingly. The trailer will be loaded with concrete ballast and sandbags to achieve a Gross Vehicle Weight Rating as near 80,000 lbs as possible without exceeding the Gross Axle Weight Rating for any axle. The ballast will be secured with load frames (previously used in Truck Rollover Characterization Testing conducted by the partners) and binders to prevent movement and provide load control during testing. A steer axle weight limit of 12,000-lbs is standard on the 56 0 0 0 0 0 0
conventional 6x4 tractor, while the drive and trailer axles shall be loaded up to the limit of 17,000-lbs per axle. 4.3 Tires The duty cycle testing will evaluate the effect of tire type on vehicle fuel economy. Michelin will provide the tires shown in Table 4.1 for HVDC testing. Table 4.1 Tire Sizes and Types No. of Tires Tire Size 2 XZA3 275/80R22.5 8 XDA-HT 275/80R22.5 8 XT1 275/80R22.5 4 Xone XDA-HT PLUS 445/50R22.5 4 Xone XTE 445/50R22.5 For each duty cycle route, the vehicle will be configured with standard dual tires (275/80R22.5) for the first run. On the repeat route, the vehicle will be configured with new generation singles tires (445/50R22.5). The route verses tires are shown in Table 4.2. Table 4.2 Tires Per Route Steer Drive Trailer Chicago-Portland #1 XZA3 XDA-HT XT1 Chicago-Portland #2 XZA3 XOne XDA-HT Plus XOne XTE Maine-Miami #1 XZA3 XDA-HT XT1 Maine-Miami #2 XZA3 XOne XDA-HT Plus XOne XTE The pressure shall be maintained at 116 psi for steer, 104 psi for drive and trailer dual tires, and 120 psi for drive and trailer new generation single tires. Tire pressure will be monitored, maintained, and recorded manually on the HVDC Daily Log Sheet. The driver will check and log tire pressure as part of the pre-trip inspect prior to driving each day. 4.4 Fuel During the Pilot Test (as will be during the Field Testing), fuel will be purchased where convenient and practical for the driver. For the Pilot Test ORNL and Dana will share the cost of the fuel. The driver will record the amount of fuel at each fill-up and the miles driven between fill-ups on the HVDC Daily Log Sheet (Figure 4.1) for cross-checking of fuel usage sensors. Each tank will be filled to a predetermined index mark on the tank to reduce the error in determining the amount of fuel required for a given fill-up. It is known that the total energy density of fuel will vary from production run-to-production run and from season-to-season. During the Pilot Testing Phase fuel sampling and assaying may be done to determine the energy density variability in order to relate this to total fuel consumption. 4.5 Pilot Test Routes 57
