The objective of the initial phase of the project was to identify, develop, analyze, and evaluate potential methods for stopping heavy vehicles on long, steep downgrades. Four categories of methods were examined: (1) devices for arresting aircraft in emergency landing or take-off situations, (2) crash cushions of barriers, (3) retarders which are part off the vehicle, and (4) escape ramps utilizing an arresting material and/or an ascending grade. Using criteria of arresting capability, safety, reliability, down time, cost effectiveness, and adaptability to truck use, vehicle retarders and arrester beds were found to be the most feasible methods of arresting run away heavy vehicles. The extension phase has as its objective to examine the energy dissipation properties of a variety of materials covering a variation of particle size, particle shape, vehicle velocity, and wheel load.
