A Method for Assessing Costs Associated with Conversion/Reconversion of Low-Volume Roadways

Abstract

This paper presents an explanation of the methods used to evaluate the costs associated with the conversion of low-volume roads to gravel and asphalt, as well as the potential reconversion to the original surface type, for the purpose of maintenance cost savings. Across the country, agencies are converting lesser-used surfaced roads into un-surfaced (gravel-type) roads in order to curtail present maintenance spending. But the conversion costs money, and there is the possibility that growth may occur that would necessitate the reconversion of the roadway, an expensive task that could negate any potential savings from the initial conversion. The conversion and maintenance costs are dependent on local material costs and road standards. The feasibility of this practice requires a more in-depth look at the costs involved with both conversion and maintenance of both surface types, as well as potential for growth in the area. This paper presents the minimum costs associated with conversion and reconversion of low-volume roads in Texas as an example of one way to assess costs for decision-making purposes.
