Abstract
An asphalt based sealer for driveways and the like is disclosed. The material uses a blend of solvent deasphalted (SDA) asphalt blended with a cutter stock as the binder or sealer base. Driveway sealer (an emulsion of clay, water and binder) made with this binder has acceptable durability and can be essentially free of coal tar pitch, greatly reducing the toxicity and odor of the sealer.
