    • Abstract:
      A maintenance issue that has the potential for cost savings is the maintenance of gravel shoulders. Maine

      has 5600 miles of roadway with gravel shoulders that erode with heavy rains. Every year the gravel

      shoulders erode to a point were the gravel shoulder elevation is as much as 2 inches below pavement elevation and isolated areas can be washed away to a depth greater than that. This elevation change can make it very difficult to control a vehicle that has wandered into the gravel shoulder. In addition, when a gravel shoulder is even with the pavement it gives support to the pavement edge. When the gravel is

      below the pavement surface that support is diminished and trucks or vehicles that ride along the pavement

      edge can ravel and crack the pavement. This occurs mainly on inside curves and over time, the cracking

      can migrate into the wheel path decreasing the load carrying capacity of the roadway. Based on the

      Departments Maintenance Activity Tracking System, which is a work accomplishment database that

      records labor, equipment, and material costs for all maintenance activities, the Department spends as

      much as 1.14 million dollars per year to re-grade and compact gravel shoulders.

      One way to decrease the cost of maintaining the shoulders and improve safety is to add a binding agent to the gravel prior to re-grading and compaction. This could prevent rain water from eroding the gravel and add stability to the shoulder which could reduce pavement edge ravel and cracking and increase the life

      expectancy of the roadway.
