Abstract: The US Air Force uses an aircraft arresting system on many of their runways for emergency stopping of aircraft. It consists of a 1- or 1-1/4-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 the most promise were field-tested at Homestead and Tyndall Air Force Bases. AFESC requested an additional study in 1983 to find other materials than those tested during 1980-81 and to test the more promising of these materials. A survey was made to locate new materials and the more promising materials were tested. Based on the test results, two of the better materials were field tested at Seymour-Johnson Air Force Base. This report gives the results of the laboratory and field testing. It also describes problems encountered with some materials and the solutions required to make them useful.
