    摘要： A prepared ground surface e.g. a pavement or roadway is provided with a free-draining aggregate layer between it and subsoil, there being positioned above and beneath the aggregate layer a water impervious barrier to prevent water entering the aggregate from passing downwardly into the subsoil or upwardly into the pavement or road surface material. In one embodiment the angle of the bottom impervious layer is such that water flows through beneath the roadway surface. In another embodiment water from either side of the roadway or pavement surface can flow to a central or midpoint and is the means for draining away water tending to collect therein. In one form the means comprises an interceptor section or gully conducting water longitudinally to a point of discharge.

    摘要： A permeable fabric or film, e.g., an on-woven polyolefin such as polypropylene, is treated on one side with a carrier containing seed and comprising a water-soluble material or gum, e.g., carboxymethylcellulose. A filler, e.g., subdivided cellulose and/or a fertilizer, e.g., ammonium nitrate, can be incorporated into the carrier. The other side of the fabric or film is coated with asphalt applied as a dilute emulsion wash, or the fabric can be at least partially saturated with asphalt. The thus treated fabric or film is placed seed treated side down on and can be fastened to the ground to produce accelerated seed germination and growth and to protect against erosion until a desired stand of ground cover has been grown. When degradation of the fabric or film is desired, it can be chosen to be an ultraviolet degradable material, e.g., unpigmented polypropylene. by varying the amount and/or dilution of asphalt or of asphalt emulsion or other material combined with the film or fabric selected periods of time of slope reinforcement can be obtained. A radiant heat absorbent material e.g., a dark pigment, such as carbon black, can be incorporated into the asphalt or similar wash.

    摘要： The hydrocarbonaceous substance, e.g., a petroleum asphalt cement such as a residual, pitch, Trinidad asphalt, etc., is composited with an oil shale which has been ground to an average particle size of less than about 75 microns and then eminently admixed with the hydrocarbonaceous material at a temperature in the approximate range 250*-375*F.
