Moisture In Asphalt Production | Agg-Net

If a plant produces 300 tonnes of asphalt per hour at 6% moisture, it will be using 1,200 litres of fuel per hour to dry the aggregate before it is heated up to the correct temperature. If the moisture content then changed from 6% to 5% without the dryer being adjusted for 1h, that would equate to 180 litres of fuel being wasted in that 60min ...
