  • Mechanical anchorage in resinous composition for sealing strip
    Patent number: 4456398
    Abstract: An expansion joint for bridges and similar structures comprising an elastomeric sealing element, anchoring means gripping the sealing element and resin mortar connecting the anchoring means to the structure. The resin mortar is comprised of a mixture of ureide and epoxy resins and aggregate. The anchoring means has rods embedded in the resin mortar to distribute stresses therein.

  • Compositions for use in seal coats
    Patent number: 4296167
    Abstract: A seal coat for use in a traffic surface is formed by reacting a first component comprising a liquid epoxy resin and a blocked polyisocyanate prepolymer with a second component comprising an aliphatic or cycloaliphatic polyamine, and allowing the mixture to cure. Advantageous results are achieved if the mixture, before curing, is allowed to impregnate a matrix, e.g. a non-woven synthetic material.

  • Process for the preparation of a coating composition for roads, airports and industrial floorings
    Patent number: 4120832
    Abstract: This invention relates to a coating composition for roads, airports, industrial floorings, canals and dams comprising inorganic granulates coated with 4-12 wt%, by weight of the granulates, of 25.degree.-60.degree. EVT pitch and with 5-30 wt%, by weight of the coal pitch, of ground waste plastic materials, to a process for its preparation and to the coatings obtained thereby.The coatings of this invention possess good resistance to furrowing and to punching.

  • Process for preparing a composition for the surface of roads, airport runways and like surfaces and the products obtained
    Patent number: 3953390
    Abstract: Process for preparing a composition for the surface of roads, airport runways, canals, dams and the like surfaces, comprising mineral granulates coated with 4-12% by weight with respect to the weight of the granulates, of a binder consisting essentially of 93-96% by weight of fluxed coal pitch or fluxed coal tar and 4-7% by weight of a polymer or copolymer of vinyl chloride. The polymer or copolymer is first mixed rapidly in a mixer in the form of a powder with the granulates previously heated to a temperature of 120.degree.-160.degree.C and the binder is thereafter introduced in the mixer in contact with the mixture thus obtained and the mixing of the composition is terminated in the conventional manner.
