Temperature measurement in asphalt paving (Part I)
In a modern mixing plant the power for heating the stones/aggregate can reach up to 30MW. In relation to only some kW powering the screed heaters (by gas or electricity) it is only possible to “smoothen” the surface and prevent the asphalt from sticking to the metal. But on the other side a defective screed heating can lead to a rough surface that can cause future potholes and cracks.

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 period. Were this to be the case, moisture ...
