Here at GSC, we use a coal-tar emulsion sealer known as Seal-Pave. Seal-Pave is a heavy-duty protective seal for bituminous concrete pavements.
Seal-Pave extends the service life of asphalt concrete pavements by stopping the damaging effect of petroleum derivatives, the drying effects of the sun, oxidation, and water. Seal-Pave is a high solids colloidal dispersion of coal tar pitch in water. After curing, it forms a seal of coal tar pitch fortified with inert mineral fillers.
