Abstract:

Several types of elastomeric energy absorbers were evaluated for use in a Manual for Assessing Safety Hardware (MASH) ; Test Level 4 (TL-4) energy-absorbing, urban roadside/median barrier. Twelve dynamic bogie tests were conducted on 60- ; and 80-durometer EPDM rubber cylinders. Five dynamic bogie tests were conducted on marine shear fenders. One ; dynamic test was conducted on a 27-ft (8.2-m) long installation of 2-in. (51-mm) thick EPDM rubber cylinders spaced at 8 ; ft (2.4 m) on center and attached to the front face of a 32-in. (813-mm) tall, concrete New Jersey-shaped barrier with a ; continuous 6-in. x 12-in. (152-mm x 305-mm) steel tubular front rail. One dynamic test was conducted on a 28-ft (8.5-m) ; long installation of 11⅝-in. (295-mm) tall marine shear fender posts spaced at 8 ft (2.4 m) on center with a 6¾-in. (171- ; mm) tall, upper timber rail. Both barrier concepts showed promising results. Several static tests were conducted on the ; marine shear fenders at hot, cold, and room temperatures to evaluate its effect on energy-absorber behavior.
