Abstract: 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.

Abstract: A method, structure, and composition for repairing wide and/or deep cracks, joints, and other gaps in pavement surfaces using one or a series of layers of a compressible aggregate of uniform size, with each layer of the compressible aggregate having a binder applied thereto which flows downwardly into and binds all or an upper portion of the compressible aggregate.

Abstract: An asphaltic sealant composition and method which use (a) the incorporation of one or more pigment and/or UV absorbing materials, (b) a low shear production method, and (c) the addition of an epoxidized ester of a vegetable oil or a plasticizer, effective for increasing the degree of dispersion of the pigment material in the sealant composition, to provide improve resistance to UV radiation.

Abstract: A non-asphaltic sealant composition, and methods of producing and using the sealant composition, wherein the non-asphaltic sealant composition includes a sufficient amount of one or more polar, non-asphaltic base resins having functional groups for hydrogen bonding to provide high adhesion for sealing cracks and joints in polar concrete pavements and other polar substrates.

Abstract: Hot-applied asphaltic and non-asphaltic sealant compositions and methods having or using defined effective polymer concentration (EPC) values of at least 7.0 are provided which (a) provide improved softening points and improved resilience without the use of any inorganic filler materials, while at the same time maintaining or increasing the ductilities of the compositions, or (b) enable the use of one or more inorganic filler materials to provide improved softening points and improved resilience while maintaining desirable viscosity levels and at least significantly limiting any losses in ductility or increasing the ductilities of the compositions.

Abstract: 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.
