FAQs: Why Rail Gator?
The US is moving our guardrail inventory to a new MASH /MGS mid-splice post spacing. Dig into the technical reasons here:
QUESTION 1: What are DOTs &/or Transportation Institutes saying about mid-span-splice post spacing?
TXDOT Presentation: Click Here See slide 15
Illinois DOT Shift to Mid-Span-Splicing: Click Here See slides 5; 6
QUESTION 2: What research supports the move to W-beam splice connections to mid-splice post placement?
Performance of W-Beam Splices, by Ray, Plaxico and Engstrand: Click Here Documented, controlled study of w-beam splice connection stresses
QUESTION 3: When installing new mid-span splice holes in preexisting guardrail, why are new holes not allowed to be drilled or torched for the new post locations?
The rail will be compromised: Click Here See Question 10
QUESTION 4: What about the exposed edge?
A Michigan DOT sponsored study compares the corrosion performance of hot dipped galvanized highway safety materials with no uncoated edges V/S galvanized highway guardrail components with exposed edges:
