  • Process for repairing asphalt pavement
    Patent number: 4358554
    Abstract: This invention provides a process for repairing and surfacing broken asphalt pavements which involves applying to the distressed pavement a binder composition which has exceptional solvating power for asphaltic material, and which functions to solubilize and incorporate aged pavement asphalt into the binder composition as it penetrates and fills void spaces.Illustrative of a preferred binder composition which is applied to the distressed pavement is a homogeneous blend of (1) a FCC main column bottoms residuum boiling above about 650.degree. F., and (2) an asphalt-soluble elastomer which improves the elasticity and wear resistance of the binder composition.
