  • Asphalt compositions
    Patent number: 4479827
    Abstract: An asphalt binder composition useful with aggregate particles. The asphalt binding composition comprises: (1) a medium curing liquid asphalt, and (2) from about 0.1 to 13.5% by weight tall oil based on the weight of the medium curing liquid asphalt. An aggregate containing asphalt composition is also provided which comprises the asphalt binder composition, defined above, and aggregate.
    Type: Grant

  • Asphalt compositions and method for paving
    Patent number: 4373960
    Abstract: An asphalt binder composition useful with mineral aggregate particles to form a patching composition for the repair of roads. The asphalt binder composition comprises: (1) a medium curing liquid asphalt, (2) from about 0.1 to 13.5% by weight tall oil based on the weight of the medium curing liquid asphalt, and (3) 0.0001% to 0.05% by volume of organopolysiloxane fluid, based on the volume of medium curing liquid asphalt plus tall oil. A patching composition is also provided which comprises from about 3 to 8% of asphalt binder composition, defined above, and from about 97 to 92% by weight of a mineral aggregate, based on the weight of asphalt binder composition plus mineral aggregate. A coating or sealing composition comprises: (1) a rapid curing liquid asphalt and (2) from about 0.1 to 13.5% by weight tall oil, preferably 1% by weight tall oil, based on the weight of rapid curing liquid asphalt. Methods are provided for preparing the compositions and for repairing roadways.
