Anotation

This specification presents the types, physical properties, and dimensions of rigid cellular polystyrene (RCPS) intended for use as geofoam. This specification, however, does not address the layout, placement, and workmanship for proper installation and performance of the geofoams. RCPS geofoams shall be formed by the expansion of polystyrene resin beads or granules in a molding process (EPS), or by the expansion of polystyrene base resin in an extrusion process (XPS). They may also be manufactured with reprocessed polystyrene foam (regrind). The RCPS geofoams shall meet combustibility and curing requirements and, when tested, shall adhere to physical property requirements such as dimensions and density, compressive resistance, flexural strength, and oxygen index. Final products should also meet surface damage, volume damage, and UV degradation limits.
