Utilization of Asphaltum Residues. ANon. (Oil, Paint and Drug Reporter, June 24, I912.)--It is shown by the Geolo~eal Surveys publication, " Mineral Resources," that the chief feature of the asphaltum industry in 1911 is the great extension of the use of residues from the asphaltic varieties of petroleum as binders on the surfaces of macadam roads in order to prevent deterioration. The asphaltum used for this purpose increased from 159,424 tolls in 191o to 234,951 tons in 1911. The importation of soft asphaltum from Venezuela, which is admirably suited for this purpose, is. increasing. A by-product of the oil industry is fast supplying the demands for asphaltum in the United States. The petroleum from California and Texas has furnished large supplies of asphaltic residue, which, when treated with air, becomes sticky and even elastic to a certain extent. Elastic material for roofing and substitutes for rubber in automobile tires have been obtained from asphaltic residues by the blowing process or by treating with sulphur. This sulphurization of asphaltum has been applied with good effect to elaterite and similar hard asphaltums from eastern Utah.
