4 Tips to Consider When Calibrating Your Asphalt Plant

2020-5-20  1.) Check all Hardware. 2.) Confirm Your Weighbridge is in Proper Alignment. Extremely Important: Use the leveling bolts to adjust the scale idler height. Use a minimum of three strings to align all five weighbridge idlers, one at the tip of each wing roller and in the middle of the center roller.

Procedures for Checking Asphalt Drum Mix Plants

2020-6-24  The scales used for plant calibration must meet Section 915.01.04 . BELT SCALES ON COLD FEEDERS . Plants will check each individual belt scale, including RAP, at its high range and low range, as rated by the manufacturer; also considering the plant’s actual production rates. A minimum of ten tons of material will be used per test run.

Calibrate Your Lab Equipment on Schedule AsphaltPro

Having lab equipment in proper calibration gives you a better chance at proper measurements and testing results. Dan Ridolfi of Lastrada Partners, El Dorado Hills, California, stated the calibration and maintenance of lab equipment is just as important as the calibration and maintenance of the asphalt and aggregate equipment at the plant.

Asphalt Calibration System Stansteel Asphalt Plant

Liquid asphalt can be calibrated and weighed by a separate holding vessel that is supported on multiple load cells and calibrated with a known weight. In order to ensure the accuracy of the liquid asphalt metering system, it is mandatory that the hot mix producer runs a calibration check on their asphalt metering on a periodic basis.

Build the Test Section for Validation of Plant Produced

This calibration can be performed during the plant production to ensure that the lab is set up to accurately measure the asphalt content as soon as full scale production begins. At any time during the project, changes in aggregate sources or significant changes in the mix volumetrics may require that a
