AASHTO bridge design specifications were updated this year, with the largest change to designs for Mechanically-Stabilized Earth (MSE) walls in more than 20 years. TRB will host a webinar on Thursday, October 8, 2020 from […]
There is a neat little blurb in Roads and Bridges magazine on a small mechanically stabilized earth (MSE) retaining wall at NASA’s Wallops Flight Facility on the Coast of Virginia. The wall was designed and […]
Carolina Sunrock constructed a new primary crusher and needed a 51 foot tall retaining wall to create the grade separation. They went with a Redi-Rock faced wall, and were in the unique position to buy […]
Here’s a press release from Rensselaer about their students winning the MSE wall competition at the Geo-Frontiers conference. Congratulations guys! [Source: Rensselaer via ASCE SmartBrief. Image: RPI]
Republished from the ER-2010 conference, this paper by Michael R. Simac and David J. Elton describes the performance of two of the first geosynthetic reinforced soil walls for integral bridge abutment construction in North America […]
Another case study from RetainingWallExpert.com, this one for the failure of a 38-ft high geogrid-reinforced modular block MSE retaining wall. They note that the failure of the retaining wall follows their typical recipe, ‘Just Add […]
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 […]
ADAMA Software has released update 11 for their Mechanically Stabilized Earth retaining wall design software, MSEW 3.0 as of October 23, 2010. It appears that the changes mainly involve adding the updated AASHTO LRFD seismic […]
ADAMA Software has released update 13.1 for their Mechanically Stabilized Earth retaining wall design software, MSEW 3.0 as of August 30, 2011. Some of the design methodology changes in the 2009 FHWA manual for MSE […]
The ARES wall system is a geosynthetic reinforced MSE wall with a concrete panel facing. Most concrete panel systems use metallic reinforcement. On this project, the on-site backfill soil did not meet electrochemical requirements for […]
