摘要： The disclosure describes asphalt saturated felt building materials, optionally having a mineral filled asphalt base coating thereon, in which the asphalt saturating the felt and/or the asphalt in any mineral filled coating is a blend of 10-55% sulfur dispersed in the asphalt. The materials are used in the conventional manner as roofing felt, roofing shingles, and in built-up roofing, to obtain improved fire resistance.

摘要： A process for preparing a paving asphalt cement comprising two steps. In the first step, a high quality paving asphalt precursor, a low quality paving asphalt precursor, a non-paving asphalt precursor or a mixture thereof are catalytically oxidized to form a paving asphalt cement. In the second step, the catalytically oxidized paving asphalt cement is mixed with one or more of a high quality paving asphalt precursor, a low quality paving asphalt precursor, a non-paving asphalt precursor or a mixture thereof.

摘要： The disclosure describes built-up roofing having improved resistance to spreading of fire, fabricated from two or more layers of felt impregnated with asphalt based saturant with asphalt based coating spread on top of each felt layer; the saturant asphalt or coating asphalt or both are blends of 90 - 45% asphalt with 10 - 55% sulfur. The roofing is built-up in the conventional manner by "mopping" fluid asphalt based coating onto felt layers impregnated with asphalt based impregnant. A protective layer of inert mineral aggregate (e.g. gravel) optionally covers the top coating.
