Lowered engine, since the original pistons came up between the seats. Enabled tilting of the cab to see engine underneath. Minor optional aesthetic tweaks - a fan on the engine, hub caps on front four

Procedures for Checking Asphalt Drum Mix Plants

The Administration will check belt scales at the mid-range using the procedure listed below. PLANT TEST PROCEDURE: 1. Each bin and its belt scale are tested individually. 2. Some plants may have to use a zero percent moisture input to ensure accuracy. 3. Check the belt scale accuracy at both high range and low range by running material over the

4 Tips to Consider When Calibrating Your Asphalt Plant

3.4 Calibration of Asphalt System The calibration of the asphalt system of a dual belt scale plant is similar to a single belt scale plant. The weight per revolution or unit volume is determined and then the asphalt content is checked by diverting asphalt back to the storage tank. With a dual belt scale recycle plant there are other variables besides the production
