  • Asphalt compositions and methods of preparation thereof
    Patent number: 6228909
    Abstract: Systems and methods for combining a mineral acid and a polymer additive in an asphalt composition are described. Methods of preparing a polymer modified asphalt include providing a source of a neat asphalt; heating the neat asphalt; providing a source of a polymer; adding the polymer to the neat asphalt to form a blend; providing a source of a dilution asphalt; and adding the blend to the dilution asphalt to form a diluted product. The systems and methods provide advantages in that the addition of the mineral acid widens the temperature range in which satisfactory performance from a given polymer asphalt composition can be achieved or, as a corollary, reduces the amount of polymer additive that would otherwise be needed to achieve satisfactory performance within a given temperature range.
    Type: Grant
