An investigation was conducted to determine the potential use of expanded polystyrene concrete as a subbase material for pavements, particularly in areas where severe winter conditions prevail. The work included experimental and analytical evaluations. Measurements taken on pavement sections in an outdoor test installation indicated that expanded polystyrene concrete is effective in reducing or even eliminating subgrade frost penetration under rigid and flexible pavements. In addition, expanded polystyrene concrete subbases reduce pavement deflections. The results of an analytical investigation indicated that expanded polystyrene concrete subbases effectively reduce or eliminate subgrade freezing under pavements. Expanded polystyrene subbases also reduce pavement and subgrade stresses, thereby increasing the load-carrying capacity of pavements. /Author/
