The Geotechnical Group of the Office of Bridge Technology has been involved in the development and national acceptance of mechanically stabilized earth walls (MSEW) and reinforced soil slopes (RSS). These combined technologies have been extensively implemented into national transportation practice and provide significant cost-savings and pleasing aesthetics compared to other earth retention systems. The majority of FHWA's technology development and deployment activities on this subject were accomplished within the scope of the Demonstration Project No. 82 which concluded in September 2000. The workshop segments of the demonstration project have been recently updated and are available as National Highway Institute Courses 132042 (Design and Construction) and 132043 (Inspection). Additional information on these NHI courses can be found at http://www.nhi.fhwa.dot.gov/. Concurrently with the course updates, design and construction reference materials have been updated to reflect the latest recommendations in soil reinforcement technology. The revised publications are available from the FHWA Reports Center (FHWA-NHI-00-043 and FHWA-NHI-00-044). The Reports Center can be reached by phone at 301-577-0818 or by email at email@example.com.
This memorandum announces the availability of the computer program ReSSA 1.0 developed by ADAMA Engineering, Inc. The program follows the latest reinforced slope design guidelines and recommendations as presented in the new NHI course and reference manual, and it will be of interest to geologists, and geotechnical and structural engineers. The ReSSA program permits the user to design or analyze a range of reinforced slope problems by a variety of slope stability methods. There is a wide range of options specifically designed to accommodate most input variables encountered on both simple and complex reinforced slope problems. The program interface is modeled after the widely popular program, MSEW, and users are provided extensive help and output options.
The ReSSA 1.0 program is copyrighted and password protected. The FHWA is authorized by the developer to distribute a limited number of copies of the program to Federal agencies and State departments of transportation. Complete details on obtaining the ReSSA 1.0 program can be found in the attachment.
Please forward the above information to appropriate individuals within your office and State DOT offices. Organizations and individuals interested in the program who are not covered under the FHWA license can contact ADAMA Engineering, Inc., at 302 368-3197, or http://www.geoprograms.com/ for additional information. General questions regarding the subject program may be directed to Mr. Chien-Tan Chang at 202 366-6749. Specific technical questions should be directed to Mr. Jerry DiMaggio at 202 366-1569. Program updates will be posted on the Geotechnical Section of the Office of Bridge Technology Web site (http://www.fhwa.dot.gov/engineering/geotech/).
