An economical asphalt emulsion based crack filler designed for filling cracks up to 1/4 inch in width in asphalt pavements. It is formulated as a low viscosity liquid which allows it to be poured into small cracks easily and uniformly. It is intended to be a general purpose, cost effective crack sealant for non-structural cracks. It should not be used on cracks deeper than 1/2 inch or that extend through the pavement.
