Laboratory and field investigations were performed on several commercially available rigid polyurethane foam materials to determine their suitability as base replacement materials for full-depth portland concrete cement (PCC) pavement repairs. Rigid polyurethane foam (RPF) specimens were prepared and tested to evaluate the compressive strength, reactivity, and density of several foam materials under a variety of temperature conditions, where properties were investigated for thermal variations expected in field placement. Following laboratory testing, full-scale field testing of full-depth PCC repairs was conducted using two RPFs of densities of approximately 160 kg/m(3) (10 lb/ft(3)) and 240 kg/m(3) (15 lb/ft(3)) to verify laboratory predicted performance under elevated and ideal field temperatures. Each repair was trafficked within 3 h of repair completion with an F-15E load cart to simulate fighter aircraft traffic on early-age repairs. Results of laboratory and field testing indicate that high-density RPF materials are suitable as base replacement materials for temporary pavement repairs on airfields. For optimum field performance a RPF with minimum density of 240 kg/m(3) (15 lb/ft(3)) should be placed at a temperature of 23 degrees C (70 degrees F).
