ABSTRACT:
A portland-cement stabilized soil base for a roadway is covered with an elastic rubber-asphalt layer and thereafter with a surfacing layer. The elastic layer may be formed by reacting 1 to 30% by weight of asphalt with 99-70% by weight of rubber and be applied hot as by spraying; and the surfacing layer will ordinarily be asphalt concrete composed of asphalt binding aggregate particle such as coarse stone, together. Preferably the elastic layer covered with a layer to prevent bonding of the elastic layer with an overlying asphalt concrete layer. Such bonding-preventing layer may be finely crushed stone, roofing paper, non-woven fabric, or plastic film, or the like.
