Asphalt production process

Sep 04, 2020

Jun 28, 2018 Wolf Paving's Asphalt Production Process. To produce our asphalt we use various sizes of aggregates and two different sands, manufactured sand and natural sand. The sand used will depend on the mix being produced. The aggregates are loaded into the feed bins, and the computer controls the amount of aggregate that goes into the asphalt mix
