From page 594... ... 10-2 were obtained from actual geofoam construction drawings from projects throughout the United States and can be used as a guide for developing site-specific drawings or details. The details presented relate to a variety of geofoam issues, such as, configuration of the EPS blocks, inclusion of utilities and roadway hardware, construction of a load distribution slab over the EPS, and anchoring of the EPS blocks to resist hydrostatic uplift.

From page 595... ... 10-3 illustrates that use of EPS-block geofoam above on-site basalt tunnel mine spoil that is geosynthetically reinforced to increase stability. This cross-section shows that geofoam can be used with on-site material to produce a cost-effective design for roadway embankments. Read the entire page →
From page 596... ... 10-4 DESIGN DETAILS FOR BRIDGE ABUTMENTS This section of Chapter 10 presents construction details for the use of geofoam in bridge abutments. This is an important application of geofoam and involves drawings for both the embankment/abutment interface and the pavement system overlying the geofoam. Read the entire page →
