A method of sealing pavement joints includes the steps of dispensing a first band of void reducing joint composition on a substrate. Applying a first pass of pavement over at least a portion of the void reducing joint composition. Dispensing a second pass of void reducing joint composition on the substrate. Applying a second pass of pavement of the second band of void reducing joint composition and against an edge of the first pass of pavement.

Void reducing asphalt membrane composition, method and apparatus for asphalt paving applications

A binder composition for asphalt pavements that includes: an asphalt binder; an elastomeric polymer; a wax modifier; and optionally at least one of: i) fumed silica or fumed alumina; and ii) a saponified fatty acid and a resin acid gelling compound. The composition is applied as a tack coat and/or a stress absorbing membrane interlayer and is non-tracking.

Binder composition for improved tack coat and stress absorbing membrane interlayer application for road construction

A method of installing an asphalt pavement, which method involves: identifying a surface to be paved; applying a non-tracking layer of binder composition to the surface; and permitting the application of an asphalt layer over the non-tracking layer of binder composition. The binder composition consists essentially of: at least one asphalt binder; at least one elastomer; and ethylene bis stearamide. In a further embodiment the binder composition consists essentially of: at least one asphalt binder; at least one elastomer; sulfur; and ethylene bis stearamide. The composition is applied as a tack coat and/or a stress absorbing membrane interlayer and is non-tracking.

A void reducing asphalt membrane composition for asphalt pavements that includes: an asphalt binder; an elastomeric polymer; a wax modifier; and at least one of: i) fumed silica or fumed alumina; and ii) a saponified fatty acid and a resin acid gelling compound. The composition is resistant to flow when applied and migrates into hot mix asphalt in the area of the longitudinal joint to reduce air voids to 7% or less and reduce water permeability. The composition becomes tack-free quickly after application. The composition bonds to asphalt, concrete, brick, stone and metal.

An apparatus for applying an asphalt binder composition to a roadway during construction or repair of an asphalt pavement which apparatus include: a mobile vehicle having a chassis extending in a longitudinal direction which longitudinal direction is aligned with a forward/rearward direction of travel of said mobile vehicle; at least one storage tank supported on the chassis containing an asphalt binder composition; and at least one spray nozzle configured to dispense the asphalt binder composition from the at least one storage tank in a longitudinal strip or band having a width that is no greater that a width of the asphalt binder composition dispensed by one of the at least one spray nozzle. The at least one spray nozzle can include a plurality of spray nozzles that are coupled to a common spray bar. According to one embodiment the asphalt binder composition is a void reducing asphalt membrane composition that is provided between adjacent asphalt pavement passes.

Apparatus and method for applying asphalt binder compositions including void reducing asphalt membrane compositions for paving applications

A roadway structure that includes: a substrate; a hot mix application portion positioned over the substrate, wherein said hot mix application portion comprises first and second adjacent paving passes defining a longitudinal joint, and wherein the first and second adjacent paving passes contain air voids along the longitudinal joint; and a spray-applied band of void reducing joint composition positioned between the substrate and the hot mix application portion, wherein the band is below the longitudinal joint, and wherein at least at portion of the void reducing joint composition fills at least some of the air voids.

A method of forming a pavement construction joint that involves dispensing a band of a void reducing joint composition on a substrate using at least one spray application vehicle, wherein the band comprises a width of about 4 to about 24 inches. A paving pass is applied over the band of joint composition, wherein the paving pass is positioned against an edge of a previously laid portion of pavement to form a pavement construction joint having a volume of air voids. At least a portion of the joint composition migrates upward to reduce the volume of air voids. The composition is resistant to flow when applied and migrates into hot mix asphalt in the area of the longitudinal joint to reduce air voids to 7% or less and reduce water permeability. The composition becomes tack-free quickly after application. The composition bonds to asphalt, concrete, brick, stone and metal.

The present invention relates to a method for applying a crack resistant coating on a surface, where the crack resistant coating increases resistance to high vertical and horizontal movements and high shear stresses on the surface. The method comprises the steps of applying a binding material to the surface and applying an aggregate mixture within 15 seconds of applying the binding material to the surface, where the aggregate mixture comprises aggregate particles and an asphalt solution and where the aggregate mixture has a plurality of air voids, and where the binding material fills at least 15% of the air voids in the aggregate mixture (AVFA).

Crack resistant coating and method of applying crack resistant coating

The present invention relates to a method for applying a crack resistant coating on a surface, where the crack resistant coating increases resistance to high vertical and horizontal movements and high shear stresses on the surface. The method comprises the steps of applying a binding material to the surface, applying an aggregate mixture within 15 seconds of applying the binding material to the surface, and allowing the binding material to fill some of the air voids in the aggregate mixture to form a substantially voidless layer with a height of at least 0.38 cm.

The present invention is directed to a rut resistant coating and a method for applying the rut resistant coating on an existing surface for increasing resistance to high vertical and horizontal strains and high shear stresses. The method includes applying a binding material layer of the rut resistant coating on the existing surface to provide a substantially impermeable moisture barrier to the existing surface, the binding material layer containing less than about 11% of the total binding material of the rut resistant coating. After applying the binding material layer, an aggregate mixture layer is applied on the binding material layer to provide the wear surface of the rut resistant coating and support and structure to the rut resistant coating to resist rutting, the aggregate mixture layer containing an asphalt solution.
