ABSTRACT OF THE DISCLOSURE Means for controlling the moisture content and ultimate freeze-thaw cycle parameters of a paved roadbed: including, a combination of electrolytic means together with the conventional roadbed, the electrolytic means being utilized to control the moisture migration through the soil in and around the roadbed. The system comprises a combination of a roadbed having a centrally disposed paved zone flanked by lateral shoulder zones, and electrolytic means along the shoulder zone slopes for controlling the moisture migration through the surrounding soil. The electrolytic means includes a plurality of spaced electrodes, including a plurality of anodes and a plurality of cathodes arranged in spaced-apart but electrolytically coupled relationship along the lateral shoulder zone slopes. The anode means includes crushed rock high in certain metallic oxides, with the oxides selected from the group consisting of calcium oxide and magnesium oxide such as, for example, crushed dolomitic limestone or basalt. The anodes are arranged in generally parallelly disposed openings formed in the lateral shoulder slope areas. The cathode means includes pulverized coke, pre- ferably metallurigical coke disposed in openings spaced from but adjacent to the anode openings, and being located either along the same side or the opposite side from the anodes.
