 | EPS Geofoam Presentation US Department of Transportation (DOT) & Federal Highway Administration (FHWA) Article about EPS Geofoam. Centered on Service: "Virginia Demonstration Showcase EPS Geofoam Installation on Display" This article starts with, "When working on projects, do you occasionally run across situations where the underlying soft soil is too soft and compressible to carry designed loads, or the estimated time-rate of settlement of an embankment exceeds acceptable standards? Have costly corrective fill measures still resulted in significant settlement or decreased stability over time? Do you deal with failing slopes, excessive culvert loads, or problems with high lateral loads behind retaining structures? Expanded Polystyrene Geofoam (EPS Geofoam) could be your answer!" What is Geofoam? EPS Geofoam is a rigid foam plastic engineered with a unit density as low as 1-pound-per-square-foot, thus delivering a material that is 100 times lighter than most soils. In particular situations this extreme difference in density makes EPS Geofoam an attractive fill option. A lightweight manufactured molded block, EPS Geofoam can be easily cut to any size or shape at the job site. Additionally, as an embankment soil alternative, EPS Geofoam can be covered to look like a normal slope embankment or finished to look like a wall. This technology, when properly applied in the appropriate situation is a field tested, budget-friendly winner. Here is a look at some of the less obvious but very important field proven benefits: Accelerated construction, Payroll, transportation and equipment cost savings, Reduced labor time for construction, Exerts little or no lateral load on retaining structures, Easily constructed in limited right-of-way situations, Allows application in adverse weather conditions. US Department of Transportation (DOT) & Federal Highway Administration (FHWA) Article about EPS Geofoam. Another US Department of Transportation (DOT) & Federal Highway Administration (FHWA) Article about EPS Geofoam. Priority, Market-Ready Technologies and Innovations. "Expanded Polystyrene (EPS) Geofoam. What is EPS Geofoam? What are the advantages of EPS Geofoam for highway construction? Benefits include Accelerates foundation construction, which reduces project schedules. Saves money. Requires limited labor for construction. Exerts little to no lateral load on retaining structures. Can be constructed easily in limited right-of-way areas and in adverse weather conditions. Successful Applications: States' results demonstrate EPS Geofoam advantages Deployment Goal: By October 2008, EPS Geofoam will be a routinely used lightweight fill alternative for State DOTs on projects where the construction schedule is of concern.

Expanded polystyrene (EPS) Geofoam blocks using conventional spread foundations support the new Ford PRC building. ASTM Designation D 6817-02 Standard Specifications for Rigid Cellular Polystyrene Geofoam test results. Royal Foam INC, Royal Foam Company, Royal Foam Enterprises location. Noxt to Jaxport, Jacksonville Port Authority. Railroad access. 85,000 square foot manufacturing facility. EPS block molding process. Soft soil problems and solutions Weight Comparisons: Regular backfill, sand, saw dust, shredded tires, EPS. Note: The low density of Geofoam is beneficial because seismic inertial force is proportional to the mass of the embankment. Thus, the lower density of Geofoam may alleviate the costs of soft soil removal and the possible need for an excavation support system, excavation widening, and temporary dewatering.
