Abstract:
A fabric is asphalt or bitumen coated and then adhesively coated at least on one side with plasticized sulfur. Bitumens including asphalt and asphalt emulsions now available are applicable. Hot melt application which can be followed immediately by the plasticized sulfur is possible. The product, which is flexible, solvent, weather resistant and light reflecting, and can be used for water-proofing as in roofing, road liners, pond and ditch liners, as wrapping material, it can be packaged as in rolls for marking stripes on tennis courts, athletic fields. Also, it can be used as pipe wrap, tank cladding and for decorative purposes.
Abstract:
In construction or repair of a railway road bed a base section of particulate matter is laid and consolidated with polymer: resin:solvent emulsion, a layer of ballast is added, the ties and rails are laid, and additional ballast is laid between the ties and at the ends of the ties to a height and width sufficient to produce a curb on top of the base section and outside the ties. This curb is then consolidated by treatment with this emulsion leaving the center strip and the layer of ballast immediately below the rails unconsolidated to facilitate subsequent leveling or repair.
Abstract:
THE LOW TEMPERATURE DUCTILITY OF ASPHALTS IS IMPROVED BY INCORPORATION OF A SMALL AMOUNT OF A BLEND COMPRISING RUBBER, A HEAVY RESIDUAL PETROLEUM OIL HIGH IN AROMATICS, AND CARBON BLACK. ASPHALTS CONTAINING A LIQUID OIL-RUBBERCARBON BLACK BLEND CAN BE USED IN PAVING COMPOSITIONS AND THE LIKE.
