5 Common Mistakes In Asphalt Pavingpaving asphalt

Paving asphalt is a tricky job that is driven on precision and the right mix designs. Having a strong understanding and a well educated crew will help you eliminate some mistakes but mistakes are something that can tend to be unavoidable. The best thing is to learn from mistakes, constantly be teaching and also never stop reading and learning new tips and techniques. Below are five common mistakes to avoid that will help overall improve your pavements.

Number 1: Not controlling the head of material

  • 95% of mistakes are due to improper head of material and allowing for fluctuation. It increase chances of speed bumps and waves in the final product.
  • Solution: There are plenty of new technologies out there that can help control the head of material accurately with sensors. By providing hands on training  for the new equipment, you can prevent this issue from coming up.

Number 2: Turning the depth cranks too much

  • Doing adjustments on the depth cranks throughout paving can bring issues of waves and bumps in the final product.
  • Solution: Hands on training will help break the habit of adjusting the crank. Aside from the minor occasional adjustments, the crank shouldn’t be moved often.

Number 3: Changing speeds or paving asphalt too fastrubberized asphalt

  • Having fluctuating speeds will not only disrupt uniformity of the product but also throw off the timing of the whole operation. This may also cause the rollers to have pressure to keep up with the fluctuating speeds. If the compactor impact spacing isn’t consistent, it may cause a washboard effect along with density issues.
  • Solution: Most pavers are equipped with speed limiters. Operators can do hands on training to learn how to use this technology to allow for a cleaner application.

Number 4:  Not using auto grade and slope control systems

  • Solution: The auto grade systems help reduce operator mistakes allowing for a smoother pavement. Just make sure they are properly configured and allow for proper training to have taken place so the operator knows exactly how to adjust the equipment.

  • A common mistake is stopping the compactor without turning at a slight angle. When stopping straight on, the indentation left behind will be much harder to level out with future passes or even get worse.
  • Solution: Again the best way to fix this is hands on training. Allow your operators to train stopping at a 20% to 30% angle. The indentations made by the roller on an angle is much easier to smooth on future passes than one straight  on.
