Abstract

The test and evaluation of two W-beam guardrail terminal systems are described. The two terminals, though quite similar, are characterized by a 4.0-ft (1.5-m) flare offset and a 1.5-ft (0.5-m) flare offset. Both designs were subjected to the four-test terminal matrix of NCHRP Report 230 with the 1,800-lb minicar and successful results are reported. The basis for the terminal designs is the breakaway cable terminal (BCT) that has been used in this country for more than 10 years. Improvements to the BCT were necessary because of 1,800-lb (800-kg) automobile impact considerations. The improvements include a nose section attached to the beam end to promote beam buckling for end-on impacts. The nose section is enclosed by a length of standard culvert material.
