Learn tips on how to find and evaluate gravel sources, making realistic specifications, how owners and suppliers working together provide quality results, and adding clay (nature's glue) to gravel surfacing. Participants from the class will leave with the working knowledge on how to improve gravel performance and life.

Crushing good gravel can be a challenge, but how can we make existing poor and tired gravel perform better? While even the best of gravels can't match the year-round qualities of asphalt, we can sweeten the mix and make them better with a small percentage of clay.

  • Hands-on review of sand, silt and clay.
  • Identify the causes of gravel road deficiencies – wash boarding, dust, float, rutting, etc.
  • The value of gravel testing.
  • Clay is the glue. Review test for fine materials in gravel.
  • Ways to lower bids for gravel.
  • Best practices for gravel road maintenance.
  • Best practices for gravel sampling, testing and acceptance.
  • Develop options to improve existing gravel quality – production, stockpiles and road surfaces.
  • Better gravel – better roads. Better roads – safer roads. Safer roads – save lives. With nearly 60,000 miles of gravel roads, the class is meant to help us create better, safer roads.

Learn how to "Make Gravel Roads Great Again!"
