  • Patent number: 9018285
    Abstract: The Arabian asphaltene reinforced polystyrene composites include a matrix of polystyrene and an asphaltene filler isolated from Arab heavy crude oil residue that is distributed within the polystyrene matrix to form the Arabian asphaltene reinforced polystyrene composite. Asphaltenes are obtained from the Arab crude oil by precipitation in n-heptane. Styrene monomer and the asphaltenes filler are polymerized by using heat to initiate in situ polymerization. Testing shows that the asphaltene reinforced polystyrene composites have improved viscoelastic properties (e.g., flexural strength) and thermal stability.

    Abstract: A product and method for repairing holes and cracks in roads, parking lots, sidewalks and other similar surfaces using a mixture of powder coating (i.e. dry paint) and a filler. The first step is to obtain the powder coating material. Any suitable powder coating material may be used, however, it is preferable to use the excess or waste powder coating material obtained from a powder coating operation. The next step is to mix the powder coating material with a filler, such as sand, pea gravel, or another suitable material. After the components are mixed together, it is applied to a surface needing repair such as a pothole in a road or a crack in a sidewalk. The mixture is cured by heating the mixture to the point where the powder coating melts and binds the powder coating with the filler and the surface needing repair. It may be cured before or after it is applied to the surface needing repair. After the mixture cures, the result is a high quality patched surface.

    Abstract: Compositions of controlled-breakage cationic asphalt microsurfacing emulsions especially formulated to provide extra-rapid setting on being deposited on paving in coating operations which may be realised during the day, or during the night, under particularly severe ambient conditions for this type of operation, that is to say at temperatures below 15° C. with relative air humidity exceeding 50%, but limited to 65%. Said compositions provide extra-rapid setting because they yield wet cohesion results exceeding 25 kgf-cm in one hour when tested by method ISSA TB-139 under the said ambient conditions of temperature and humidity.

  • Publication number: 20100179245
    Abstract: An environmentally friendly composition and related methods of use and production of an asphalt prime coat, suitable for application to a base road structure, are described herein. The composition includes an asphaltine, and an emulsion of a natural hydrocarbon resin mixed with a penetrating component, which can include a very limited quantity an organic solvent, or can omit organic solvents. If organic solvents are omitted, a hydrophobic wax can be added for moisture retention and water impermeability. Dispersion agents can be used to facilitate penetration into the base road. Rheology modifying agents and/or alcohols can be used to add flexibility, decrease curing time, and improve thickness and viscosity. The prime coat contains a lower quantity of volatile organic compounds than conventional prime coats, reducing environmental impact. The drying time of the composition is less than alternative compositions.
