Accelerating Construction with EPS Geofoam

Webinar Highlights Advancements in Transportation Applications

Solutions for accelerating construction of highway embankments on soft or unstable ground, a problem that has long challenged transportation engineers, will be highlighted in a free Web conference sponsored by the Federal Highway Administration's (FHWA) Highways for LIFE program and National Highway Institute (NHI). Scheduled for October 7, 2009, from 2:30-4 p.m. (eastern standard time), Advancements in EPS Geofoam for Transportation Applications will examine how the use of super-lightweight fills such as Expanded Polystyrene (EPS) geofoam to mitigate soft ground problems is becoming more popular. This out-of-the-box solution has enabled transportation agencies to build better, faster, and more cost effectively.

This out-of-the-box solution has enabled transportation agencies to build better, faster, and more cost effectively.

The Web conference will cover applications for EPS Geofoam in highway construction, the benefits and limitations of using the technology, design and construction considerations, and successful case studies from State transportation agencies. Information will also be provided on current updates to guideline specifications and design guidance for slope remediation.

The EPS Geofoam Webinar is part of the monthly NHI Innovation series, which is designed to bring representatives from State and local transportation agencies, industry, academia, and others up-to-the-minute information on today's highway technology advances.
