Top-mounted sockets for use with the weak-post, Midwest Guardrail System (MGS) on low-fill culverts were developed, tested, and evaluated. The system was adapted from the MGS bridge railing (and its other adaptations) for attachment to the top slab of a concrete box culvert. Three design concepts were developed and evaluated through dynamic component testing. Both lateral and longitudinal impacts were conducted on the design concepts while mounted to simulated concrete culverts. Two concepts, a cylindrical concrete foundation and a steel tube socket assembly, proved strong enough to withstand the impact loads transferred from the posts without sustaining significant damage or displacements. However, the third concept, a concrete slab, fractured and allowed the sockets to rotate back without developing the full bending strength of the posts. Thus, only the cylindrical concrete foundation and the steel tube socket assembly in combination with the weak-post, MGS were determined to be crashworthy according to the Manual for Assessing Safety Hardware (MASH) Test Level 3 (TL-3) impact safety criteria. The new top-mounted, socketed, weak-post, W-beam MGS for low-fill culverts was designed with multiple advantages over other guardrail treatments for culverts. The guardrail system has an unrestricted system length and does not require a transition when attached to standard MGS. The top-mounted system can be placed parallel to the roadway with a constant lateral offset regardless of the position and orientation of the culvert headwall. Additionally, the attachment configurations were designed utilizing epoxy anchors, enabling the system to be installed on new or existing culverts. Finally, the sockets remain undamaged during impact events, which allows for quick guardrail repairs by simply removing damaged posts, placing new replacement posts into the sockets, and replacing any damaged guardrail sections.

In this research, a W-beam guardrail system was developed for installation with the steel post attached to the top of a low-fill concrete culvert. The guardrail system was constructed with a 2.66-mm (12-gauge) thick W-beam rail totaling 53.34 m in length. The post spacing was 1,905-mm on center for post numbers 1-9 and 33-41, while the post spacing for post numbers 9-33 was 952.5-mm on center. Two full-scale vehicle crash tests, using 3/4 ton pickup trucks, were performed on the W-beam guardrail system.

The purpose of the testing reported herein was to assess the performance of the Modified TxDOT Round Wood Post Guardrail System in soil according to the safety-performance evaluation guidelines included in American Association of State Highway and Transportation Officials' Manual for Assessing Safety Hardware (MASH) for Test Level Three. The modification involved reducing the guardrail post embedment depth from 40 inches to 36 inches to reduce the soil resistance and decrease the force required to deflect the post through the soil. The crash test performed was in accordance with MASH Test 3-11 criteria, which involves a 2270P pickup truck impacting the barrier at a target impact speed and angle of 62 mi/h and mi/h and 25°, respectively. The Modified TxDOT Round Wood Post Guardrail System in soil successfully contained and redirected the pickup truck. The barrier performed acceptably for MASHTest 3-11. The maximum dynamic deflection and permanent deformatin were 44.1 inches and 37.0 inches respectively.
