Big Dig Geofoam Freeway Project Profile
Big Dig Freeway Project - (Boston, MA)
Faced with an extraordinary traffic mess, Boston needed to replace its main highway system, starting a project referred to as the Big Dig. The project included major highway interchanges to connect the new roadways with the existing regional highway system.
A lightweight solution was required to reduce stress on the underlying soil and prevent settlement while still withstanding heavy pressure from vehicles. Foam-Control EPS Geofoam was selected to provide the solution. In addition to being lightweight, Foam-Control EPS Geofoam is an engineered fill material with known load bearing properties. Additionally, with the speed of construction, installation of EPS Geofoam saved money and t ime compared to the conventional method for building dirt embankments that require drill shafts and concrete support pillars and can take months to complete.
