Abstract

The testing of a truck-arrester system that consists of a 158-m (528-ft) long bed of 0.6-m (2-ft) deep screened gravel, backed up by an array of 88 sand-filled plastic barrels, is described. The system was constructed on NY-28 east of Utica, New York, on a steep downgrade where geometric restrictions precluded building a conventional uphill escape lane. Three trial runs with a 16650-kg (37000-lb) dump truck, at speeds of 34, 66, and 90 km/h (21, 41, and 56 miles/h) demonstrated the ability of the gravel bed to stop runaway vehicles. The decelerations experienced in these tests were similar to those experienced in panic stops on dry pavement.
