Building Bridges the Geosynthetic Way

A fast and economical solution for achieving the goal of accelerated bridge construction, the Geosynthetic Reinforced Soil Integrated Bridge System (GRS-IBS) was initially developed by the Federal Highway Administration (FHWA) as part of its Bridge of the Future initiative in 2002. Now, following the success of GRS-IBS technology demonstrations in States such as Ohio and New York, one component of the bridge of the future has arrived.

Guidelines for the Preservation of High-Traffic Volume Roadways

In recent years, transportation agencies have turned to pavement preservation as a key strategy to extend the life and improve the condition of their roadway networks. With many agencies now facing decreased capital budgets, it will become critical to keep good roads in good condition. Preservation treatments and approaches will be even more important in the future, therefore, as relatively small investments in preservation activities can significantly increase infrastructure life. However, the use of many available strategies has been restricted to roadways experiencing lower traffic volume, with little use on high-volume roads.

For Soil Nail Walls, It's a SNAP

For designing soil nail walls, it's a SNAP. The Federal Highway Administration's (FHWA) new Soil Nail Analysis Program (SNAP) is a complete, easy-to-use software program for designing soil nail earth retaining structures, including both the nail and wall-facing elements of the structure. The soil nailing technique can be used for both temporary cut excavations or permanent applications.

Tap into the world's largest and most comprehensive pavement performance database with the new Standard Data Release (SDR) 25 from the Federal Highway Administration's (FHWA) Long-Term Pavement Performance (LTPP) program. The SDR is in Microsoft Access© format and is available at no charge on DVD.

FOCUS on Training: An Interactive Overview of Right-of-Way Requirements for Local Agencies

With millions of dollars in funding for local infrastructure distributed as part of the Nation's economic recovery program over the past 2 years, a new training course from the Federal Highway Administration's (FHWA) National Highway Institute (NHI) has been designed to provide a basic overview of the requirements of the Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 (Uniform Act). Any State or local government receiving Federal funding for local transportation projects must comply with the provisions of the Uniform Act.
