Description |
Low-volume roads (LVRs) make up more than half the centerline mileage in the United States, most of which are not designed. The Cornell University Local Roads Program worked with local highway agencies New York State to develop a mechanistic-empirical pavement design tool that overcomes the limitations of expertise and time of most LVR highway officials but takes advantage of the knowledge of their own LVRs. The tool developed, RoadPE: LHI, uses two common pavement fatigue criteria, surface tensile strain and subgrade vertical strain, with simplified inputs, and built-in trend analysis to determine the thickness of the asphalt layers for overlaid, mill and filled, rehabilitated, and reconstructed LVRs.
