N.C. DOT approves Tensar’s ARES and Mesa Retaining Wall Systems
Tensar International, a manufacturer or geosynthetic soil reinforcement and stabilization, has received full approval with the North Carolina Department of Transportation (NCDOT) for its ARES and Mesa Retaining Wall Systems.
As of Jan. 31, 2011, the NCDOT requires that companies submit and receive approval to build mechanically stabilized earth (MSE) walls based on the Load and Resistance Factor Design (LRFD) design methodology.
“This stamp of full approval is a reflection of Tensar’s ability to adhere to the evolving DOT and American Association of State Highway and Transportation Officials (AASHTO) regulations and design requirements,” Peter Larkin, P.E., District Manager — Grade Separation Solutions, Tensar, said in a written statement. “With full approval, Tensar can bid on all MSE retaining wall projects undertaken by the North Carolina Department of Transportation.”
The Mesa Systems previously had full approval with the NCDOT. Both the ARES and Mesa Systems are now updated to meet the AASHTO LRFD Bridge Design Specifications latest design requirements.
Tensar has also received approvals in other states for their products. Recent approvals include the following:
- California’s Caltrans approved Mesa Systems under new LRFD design methodology.
- The Ohio DOT approved Tensar’s UX geogrid design strength for ARES walls.
- The New Jersey DOT uses ARES Systems for true bridge abutment.
- The Maryland State Highway Administration approved ARES Systems precast panel .wall MSE system.
The inert properties of Tensar Geogrids permit the use of a wide range of backfills, including recycled materials and those not suitable to be used with steel reinforced wall systems, allowing contractors to save time and labor costs when installing the ARES Systems, according to Tensar.
Mesa Systems offer superior and cost-effective solutions for structural and landscaped retaining wall needs in the commercial, industrial, residential and transportation markets.
Both ARES and Mesa Systems have been evaluated by the Highway Innovative Technology Evaluation Center (HITEC) and have been utilized on hundreds of transportation and site development projects in the United States and around the world.
