Heavy Vehicle Tests of Tubular Thrie Beam Retrofit Bridge Railing

摘要

This program was directed toward further test and evaluation of a retrofit bridgerail design developed in an earlier FHWA program. In this series six tests were performed using vehicles ranging from 1840 lb (835 kg) to 40,000 lb (18,144 kg). In all tests the vehicles were successfully redirected, but some barrier modification was required to prevent vehicle rollover.
