PROPERTIES OF EXPANDED POLYSTYRENE CONCRETE AND APPLICATIONS FOR PAVEMENT SUBBASES

This report is of an investigation to evaluate properties of expanded polystyrene concrete and its application in pavement subbases in severe winter climates. Test data indicated that strength properties are comparable to those of good quality subbase materials and its insulating properties superior to those of conventional subbase materials. Also, 1-in. (25-mm) expanded-polystyrene-concrete subbase is as effective as a 3-in. (76-mm) granular subbase in reducing pavement subgrade freezing. Expanded-polystyrene-concrete subbases reduce pavement and subgrade stresses. The author concluded that expanded-polystyrene-concrete subbases have the potential of reducing pavement damage due to frost action and increasing pavement load-carrying capacity.
