Ongoing Evaluation of Full-Scale Unpaved Roads Research Test Sites

The goal of the proposed project is to evaluate past Iowa Highway Research Board (IHRB) unpaved granular-surfaced (gravel) road test sites to identify ones that could provide useful long-term performance data from additional field tests, and to develop a list of proposed sites, test methods, and analysis methods for a Phase II experimental project. Deliverables include a Data Collection Template, a Site Condition Summary, and a final report that serves as a scope recommendation and roadmap for a Phase II project.
