A pigmented asphaltic sealant composition and methods of preparing and using the sealant composition which eliminate or reduce a color contrast between the sealant composition and the road, pavement, or other substrate surface to which the sealant composition is applied.
Claims12
An asphaltic sealant composition comprising:
- asphalt in an amount in a range of from 50% to 89% by weight based upon a total weight of the asphaltic sealant composition, the asphalt having a jet black color;
- a pigment dispersed in the asphalt in an amount in a range of from 10% to 30% by weight based upon the total weight of the asphaltic sealant composition, and at a degree of dispersion, which changes the jet black color of the asphalt to a color ranging from dark brown to light brown or tan;
- and
- an epoxidized ester of a vegetable oil in an amount in a range of from 1% to 5% by weight based upon the total weight of the asphaltic sealant composition which increases dispersion and reduces sedimentation of the pigment in the asphalt.
