EVALUATION OF RESIN-MODIFIED PAVING PROCESS

The U.S. Army Engineer Waterways Experiment Station (WES) was tasked by the headquarters of the U.S. Army Corps of Engineers to evaluate the state of the art of the resin-modified pavement (RMP). This type of pavement is semirigid and semiflexible. RMP is basically an open-graded asphalt concrete mixture that contains 25 to 30% voids that are later filled with a resin-modified cement slurry grout. RMP is a tough and durable surfacing material that combines the flexibility characteristics of an asphalt concrete material with the fuel, abrasion, and wear resistance of portland cement concrete. A literature search and background analysis of the RMP process showed that the majority of in-service pavements constructed with this process are in Europe, particularly in France, where this process was developed. Visual observations of these sites indicate that the RMP process has potential for U.S. military applications. The final phase of the WES study involved the construction, trafficking, and evaluation of a 150- x 50-ft test section. Trafficking included both straight passes and pivot steer turns from the M-1 and M-60 tanks. FHWA's Accelerated Loading Facility was used to traffic the RMP test section by simulating heavily loaded, high tire pressure truck traffic. Sections of the test section were also subjected to controlled fuel and oil spillage. The evaluation indicated that RMP does have potential for several pavement uses. At an initial cost somewhere between asphalt concrete and portland cement concrete, RMP provides an alternative surfacing material for many Army pavement applications. These proposed applications include tracked-vehicle roads, hardstands, and aircraft parking aprons.
