Course Description

With almost half of the 4 million miles of the United States Transportation System are Gravel/ Unpaved this type of road is very important to the system.  As cost for labor, fuel and materials continue to outpace the current revenues, the value of proper design and maintenance of this system is paramount to the transportation needs of those traveling and maintaining this system.

Good gravel road maintenance or rehabilitation depends on two basic principles: proper grading/ compaction and use of good surface gravel.  The use of the grader to properly shape the road is obvious to almost everyone, but the quality and volume of gravel needed is not as well understood. This is particularly true when dealing with the problem of corrugation or “washboarding.” The problem is often perceived as being caused by the grader but is primarily caused by the material itself. This course will help provide a better understanding of what makes good surface gravel.

Another important matter to consider is the dramatic change in the vehicles and equipment using low volume roads. Trucks and agricultural equipment are increasing in size and horsepower. The trend is toward even larger machinery.

This course will also cover innovations in the gravel road maintenance/rehabilitation industry. There are new ways of stabilizing roads, new methods of dust control, new and different kinds of equipment available for maintenance/ rehabilitation of gravel roads, and even new surface materials such as recycled asphalt being used.
