Episode 67: Potholes and other leftovers from winter storms

By Podcasts

Just because a winter storm is over and mobility restored doesn’t necessarily mean that your done with the impacts of weather. Moisture and water leftover from winter combined with freezing temperatures and loads can cause problems for your pavements and roadside long after the storm is over.

Greg Duncan has many years of experience with the Tennessee DOT and now with Applied Pavement Technologies shares his experiences in dealing with the leftovers from winter weather.
