The US Air Force uses an aircraft arresting system on ma ny of their runways for emergency stopping of aircraft. It consists of a 1- or 1-14-inch steel cable stretched across the runway connected to a braking mechanism. When aircraft tires impact the cable, considerable damage occurs to concrete and other materials placed underneath the cable. Materials previously used were not performing satisfactorily for various reasons. A survey was made in 1980 for the Air Force Engineering and Services Center AFESC to locate materials for evaluation. Five of these were selected for detailed testing. The materials were tested for gel times, peak exotherms, bond strength, abrasion resistivity, ultraviolet degradation, resiliency, hardness, abrasion-impact resistance, effect of curing temperature, and proportioning errors. The materials which showed most promise were field-tested at Homestead and Tyndall Air Force Bases. jes
