Why RailGator?

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:

  • “Guardrail edges of C-HDG samples, despite being uncoated, corroded at similar rates and to similar severities as edges on the B-HDG samples”
