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.

A method of removing immiscible fluids such as oil spills from the surface of bodies of water which comprises placing an adsorbant compound on the water survace in contact with the immiscible fluid and maintaining contact between the surface of the immiscible fluid and the adsorbant material until the immiscible fluid is adsorbed. The adsorbant compound consists of an admixture comprising from between about 30% and 70% by weight of lead slag mineral wool, with the balance being a finely divided natural stone substance containing substantial quantities of iron, aluminum, and magnesium oxides, including such natural stones as trap rock, basalt and gabbro. The lead slag mineral wool is treated with a hydrophobic-oil-soluble hydrocarbon chain substance, such as oleic acid to wet the surface of the mineral wool prior to mixing with stone flour. The lead slag mineral wool is preferably fragmented into nodules having a diameter of, for example, from 1/2 inch to 1 inch. The composition may be also utilized for removing oil spills from lake beds or soil surfaces.

A system for dispersing aqueous effluents from a sewage treatment system utilizing a generally closed septic or sewage retention tank and a subterranean disposal field area for receiving the discharge from the septic tank. The septic tank is arranged to receive raw sewage and to retain solids and ultimately discharge aqueous fluid effluent into the disposal field area. The disposal field is normally disposed adjacent the septic tank vessel and is arranged to receive and disperse the aqueous fluid effluent discharged from the septic tank. Anode means and cathode means are arranged generally laterally of the disposal field with the anodes and cathodes being disposed on opposed sides of the disposal field. The anodes consist essentially of independent cells of crushed raw rock dolomite, hard limestone, or basalt, each of which is a naturally-occurring mineral. An additive of fused dolomite powder is preferably added to each of the anodes, in a suitable quantity as required.
