Costs Associated with Conversion of Surfaced Roads to Unsurfaced Roads

This project will evaluate the methods, costs, and economic impact of roadway surface conversion for the Texas Department of Transportation (TxDOT). Under the right conditions, converting an existing roadway from surfaced to un-surfaced can result in fiscal benefits for a transportation agency. Criteria for conversion to an un-surfaced roadway will focus primarily on the climatic conditions, soil conditions, and traffic volumes that foster a successful utilization of this technique. Once the criteria are determined, all roadways in Texas meeting the conversion criteria will be identified. The most efficient methods for conversion from surfaced to un-surfaced and vice-versa will be extracted from a comprehensive literature review and survey and then detailed. Selected roadways will be analyzed using a life cycle cost analysis to determine construction, material and maintenance costs over the life of the roadway under surfaced and un-surfaced scenarios. The economic impact of this project will be examined from an agency perspective using cost benefit analysis to determine if this procedure warrants adoption by TxDOT.
