Full Depth Reclamation Improvement Expectations

FDR is an alternative to deep rehabilitation and reconstruction techniques. It can treat all manner of distresses in the pavement structure except drainage issues and deep subgrade instability (greater than 2 feet below the existing surface). Deep subgrade issues can be treated with FDR in combination with soil stabilization. The service life of a FDR pavement is dependent on a good structural design and the adequacy of the selected treatment to mitigate the existing distress. The limiting factor of a well designed and constructed FDR pavement is often the life expectancy of the wearing surface and not the FDR layer. In optimum application situations, many agencies see their FDR treatments lasting 25 plus years.
