A Field Evaluation of the Perpetual Pavement Concept

This project will construct a perpetual pavement using Highly Modified Asphalt (HiMA) and validate the perpetual pavement concept in real world conditions by instrumenting and collecting data on a roadway in Ohio. ODOT is interested in the best way to utilize HiMA (i.e., asphalt base only, surface and intermediate only, or full depth asphalt buildups).
The goal of this research is to design, construct and monitor Ohio's first perpetual pavement built with HiMA. The results obtained are expected to provide the Office of Pavement Engineering with a model for future design, as well as the confidence needed to roll out additional designs for perpetual pavements as conditions warrant.
The results of this research will:
1. Incorporate the HiMA material into the design and construction to evaluate its cost effectiveness and constructability.
2. Investigate the perpetual pavement design software/concepts as it applies to the perpetual pavement design using the HiMA material.
3. This research has the potential for significant savings for ODOT and the taxpayer.
