Have you noticed the drum marching ever-so-slowly downhill at your asphalt plant? The weight of the drum and the weight of the aggregates you’re drying inside it will cause a downward axial thrust. It’s physics. One of the many reasons you want to counteract this downward creep is to stop the wear on equipment. Counteracting […]
Asphalt plants mix and heat the petroleum compounds and crushed rock. The asphalt is then loaded immediately onto trucks for delivery to construction sites or kept in storage silos. See a diagram (PDF) of the asphalt production process.
Step 5: Compaction of Asphalt. The pavement surface is then compacted using a combination of asphalt vibratory rollers that range in size from 3 - 10 tons. Compacting the asphalt is the last and final step in the asphalt paving process. Step 6: Pavement Marking. Pavement marking is the final step in your asphalt paving project.
