Book Description
A series of crash tests were conducted to evaluate several types of guardrails and bridge rails. Two bridge rail designs were tested and showed acceptable performance when evaluated in accordance with NCHRP 230. A three-cable guardrail was modified, and an end terminal was redesigned to obtain-good performance. The guardrail safely redirected a large and small vehicle traveling at 60 mi/h and impacting at 25 and 20 degrees, respectively. The terminal design was tested for snagging by directly impacting the downstream end. Although the device released, the vehicle rolled over. A new PL3 median barrier was designed and tested in accordance with the new AASHTO bridge rail test criteria. A 50,000-1b tractor-trailer impacted the median barrier at 50 mi/h and 15 degrees. The truck was redirected and contained, but rolled over producing undesirable occupant compartment intrusion. An 18,000-1b truck test was conducted on the modified thrie beam median barrier. The results indicated good performance.

Book Description
Background information in the conception and development of a configuration known as the Thrie beam is presented in this paper along with findings of a crash test series (five test) on this new barrier element. Basically, the Thrie beam can be described as a triple corrugated beam as compared to a double corrugated W-beam. It is 1-1/2 times the width of the W-beam, however, the corrugation geometry, especially the 3-1/4 inch (83 mm) depth, are similar. The crash test series was conducted on blocked-out steel post median barrier and guardrail systems.
