    Abstract: The asphalt with modified oil fly ash additive provides an improved asphalt binder for asphalt concrete. In one embodiment, the oil fly ash is modified to include a carboxylic acid group (—COOH) attached to the surface of the oil fly ash. In another embodiment, the oil fly ash is modified to attach 1-octadecanoate to the surface of the oil fly ash. The modified oil fly ash additive may be mixed with the asphalt cement or binder material, or mixed with the aggregate material for incorporation into asphalt concrete. The asphalt with modified oil fly ash additive improves the performance grade of asphalt binder from 64-10 to 82-10, eliminates the need for the usual commercial polymer modifier, improves the rutting resistance of asphalt concrete mixes over unmodified oil fly ash, and provides for an environmentally friendly way of disposing of oil fly ash waste.

The inventive paving process comprises the steps of injecting a heated foamable solution comprising a lubricating substance into a heated, asphalt binder to provide a heated, foamed mixture; adding the heated, foamed mixture to a suitable, heated aggregate; further mixing the heated, foamed mixture and heated aggregate to coat the heated aggregate with the heated, foamed, asphalt binder to form a heated paving material; supplying the heated paving material to a paving machine; applying the heated paving material by the paving machine to a surface to be paved; and compacting the applied paving material to form a paved surface.

  • Patent number: 8394189
    Abstract: The use of fine agglomerate mixtures and coarse agglomerate mixtures as an agglomerates filler materials in asphalt compositions. The fine agglomerate mixtures and coarse agglomerate mixtures are prepared from pyrolyzed polymeric and/or carbonaceous materials that have been refined into mixtures having consistent particle size and binding affinity with asphalt binders. An asphalt cement composition in accordance with one aspect of the present invention has an asphalt binder combined with an agglomerates filler formed from pyrolized carbonaceous material. The agglomerates filler material is generally about 1% to about 20% of the weight of the mixture of the agglomerates filler and the asphalt binder. The asphalt composition also includes an aggregate material that is mixed with the asphalt binder and the agglomerates filler. The end result is a lower cost asphalt composition that exhibits greater long range durability.
