Resin modified pavement (RMP) is a composite pavement surfacingthat uses a unique combination of asphalt concrete and Portlandcement concrete materials in the same layer. The RMP materialis generally described as an open-graded asphalt concrete mixturecontaining 25 to 35-percent air voids which are filled with aresin modified portland cement grout.

The RMP process was developed in France in the 1960s underthe trade name "Salviacim" as a fuel and abrasion resistantsurfacing material. RMP was introduced into the United Statespavements industry by researchers at the U.S. Army Engineer WaterwaysExperiment Station (WES) beginning in 1987. WES researchers werehoping to develop a cost effective and easily-constructed alternativeto portland cement concrete. Numerous full-scale field applicationshave since followed.

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