Abstract

This paper presents conventional creep test results for 0, 15 and 30% recycled-content expanded polystyrene (EPS)-block geofoam. The tests were performed on 50-mm (2-in.) cubical specimens with a nominal density of 21.6 kg/m3 under different stress levels for more than 9 months. It is concluded that the creep strain of recycled-content EPS geofoam increases with time and stress level in a manner similar to virgin EPS geofoam. As with virgin EPS geofoam, the elastic-limit stress appears to be a threshold stress level for creep strain development in recycled-content EPS geofoam.
