The primary goal of this proposal is to develop a simple to use tool that would allow local agencies to develop a mechanistic-empirical design for lower volume (<1,000 vpd) highways. The primary focus would be on pavement overlays and rehabilitation. The current tools available use older empirical-only methodologies, or require overly complicated data inputs. This requires working with local agencies to understand their capacity for data collection; determination of the critical factors that can be accounted for by a local agency; factors that are not available and need to be set up as defaults; and the allowable error of a local pavement design.
