Calibrated equipment such as asphalt distributors, scales, batching equipment, spreaders and similar equipment, should have been recalibrated by a calibration laboratory within 12 _ months prior to commencing work and every _ months thereafter,
26、by such laboratory from the date of recalibration, during the term of the contract.1.3.2 Bituminous DistributorProvide a distributor with pneumatic tires of such size and number that the load produced on the base surface does not exceed 295 kg/25 mm 650 psi of tire width to prevent rutting, shoving
27、or otherwise damaging the base surface or other layers in the pavement structure. Design and equip the distributor to spray the bituminous material in a uniform coverage at the specified temperature, at readily determined and controlled rates from 0.23 to 9.05 L/square meter 0.05 to 2.0 gallons per
28、square yard, with a pressure range of 172.4 to 517.1 kPa 25 to 75 psi and with an allowable variation from the specified rate of not more than plus or minus 5 percent, and at variable widths. Include with the distributor equipment a separate power unit for the bitumen pump, full-circulation spray ba

Equip the distributor to circulate and agitate the bituminous material during the heating process.1.3.3 Heating Equipment for Storage TanksThe equipment for heating the bituminous material shall be steam, electric, or hot oil heaters. Provide steam heaters consisting of steam coi
31、ls and equipment for producing steam, so designed that the steam cannot get into the material. Fix an armored thermometer to the tank with a temperature range from 4.4 to 204.4 degrees C 40 to 400 degrees F so that the temperature of the bituminous material may be determined at all times.1.3.4 Power
