Rail Gator FAQs
What are DOTs &/or Transportation Institutes saying about mid-span-splice post spacing?
Several DOTs, including Texas and Illinois, are advocating for mid-span splice post spacing to enhance safety and durability. Presentations and detailed slides are available that outline the benefits and technical specifications of this approach.
What research supports the move to W-beam splice connections to mid-splice post placement?
The performance of W-beam splices has been thoroughly studied, showing that mid-splice post placement can handle stress more effectively. Detailed research and study documents are accessible for further reading.
Why are new holes not allowed to be drilled or torched for new post locations in existing guardrails?
Drilling or torching new holes in existing guardrails can compromise the structural integrity of the rail, leading to safety risks. Proper procedures and guidelines are outlined to maintain the effectiveness and safety of guardrails.
What about the exposed edge in guardrails?
Studies, such as those sponsored by Michigan DOT, compare the corrosion performance of exposed vs. coated edges, indicating similar corrosion rates and severities, which supports the use of exposed edges under certain conditions.
