Resin modified pavement (RMP) is a composite pavement surfacing that uses a unique combination of asphalt concrete and Portland cement concrete materials in the same layer. The RMP material is generally described as an open-graded asphalt concrete mixture containing 25 to 35-percent air voids which are filled with a resin modified portland cement grout.

The RMP process was developed in France in the 1960s under the trade name "Salviacim" as a fuel and abrasion resistant surfacing material. RMP was introduced into the United States pavements industry by researchers at the U.S. Army Engineer Waterways Experiment Station (WES) beginning in 1987. WES researchers were hoping to develop a cost effective and easily-constructed alternative to portland cement concrete. Numerous full-scale field applications have since followed.

This paper gives a general description of the RMP process, including discussions of structural and material designs as well as construction techniques. Performance of significant field applications and the projected future of RMP are also discussed.
