TRB’s National Cooperative Highway Research Program (NCHRP) Report 663: Design of Roadside Barrier Systems Placed on MSE Retaining Walls explores a design procedure for roadside barrier systems mounted on the edge of a mechanically stabilized earth (MSE) wall. The procedures were developed following American Association of State Highway and Transportation Officials Load and Resistant Factor Design (LRFD) practices. [Source: TRB. Image: TRB]

MSEW and ReSSA Updates
ADAMA Software has released update 9.2 for their Mechanically Stabilized Earth retaining wall design software, MSEW 3.0 as of December 12, 2008. They also released update 3.1 for ReSSA 3.0, a reinforced soil slope design program on January 15, 2009. The ReSSA update seems like a relatively minor one, but the MSEW update contains a number of updates related to AASHTO LRFD resistance factors and design methods. If you are involved in MSE wall design for highway structures using LRFD, be sure to click through for a few highlights from the update and the download link.
