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.
