Asphalt Compaction Tips


Many factors can affect the outcome of your asphalt paving job, including:


  • Base Conditions – Base material and condition affect the level of compaction in a new asphalt layer. Required compaction depends on whether the layer of asphalt is on top of Portland cement concrete pavement, new asphalt concrete, cracked asphalt pavement, cold mix asphalt, aggregate base course, or sub grade soil
  • Weather – Air temperature, base temperature, wind speed and cloud cover all affect the cooling rate of the mix and the amount of compaction needed
  • Mix Temperature – Usually, the higher the mix temperature, the better the compaction result. However, there are no rules that can be generally applied to rolling temperatures. The ideal temperature is determined by a variety of factors, including composition of the mix, layer thickness, and binding agent used
  • Roller Passes – The best compaction strategy is to begin at the seams and then compact along the edge of the pavement. When pavement turns, the operator should first compact the lane with the smallest radius and press down the pavement on the next pass. Use dynamic compaction for subsequent passes, and finish the project a final roller pass to remove any remaining irregularities


Remember, to maximize asphalt compaction equipment productivity, have your equipment serviced annually by a trained, certified technician.
