Construction and Evaluation of Resin Modified Pavement

The US Army Engineer Waterways Experiment Station (WES) was tasked to evaluate the current state of the art of the resin modified pavement (PMP). This type of pavement is best described as a semirigid, semiflexible pavement. The RMP is basically an open-graded asphalt concrete mixture that contains 25 to 30 percent voids which are later filled with a resin modified cement slurry grout. The RMP is a tough and durable surfacing material that combines the flexible characteristics of an asphalt concrete material with the fuel, abrasion, and wear resistance of a portland cement concrete. The majority of in-service pavements constructed with this process are in Europe and heavily concentrated in France where this process was developed. Visual observations of these sites indicated the the RMP process had considerable potential for us military applications. The final phase of the study involved the construction, trafficking, and evaluation of a 150- by 50-ft test section.
