ABSTRACT
The report provides general guidance for the installation of the Midwest Guardrail System (MGS) adjacent to slopes. Previous full-scale crash testing of W-beam guardrail adjacent to or on slopes and relevant dynamic bogie testing of posts on or adjacent to slopes was reviewed. Based on that review, general guidance for the use of the MGS with slopes was developed. This guidance included recommended barrier configurations adjacent to slope, discussion of dynamic deflection and working width, and recommendations regarding the use of MGS special applications with slopes.
