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.

The invention comprises a product comprising a continuous phase comprising water and a discontinuous phase comprising an asphalt composition and a vinyl acetate-ethylene copolymer. A method for using the composition is also disclosed.

The present invention relates to an asphalt reinforcement comprising an air-permeable polyethylene film, and more particularly, to an asphalt reinforcement comprising an air-permeable polyethylene film prepared by adding an inorganic material to a composition comprising polyethylenes having different properties. The asphalt reinforcement comprising the air-permeable polyethylene film according to the present invention has excellent adhesive strength, constructability, flexibility and mechanical strength.

A method for producing a roadway structure includes: applying pellets of an adhesive composition to a non-tacky surface of a substrate having a support structure, wherein the adhesive composition has at least one solid epoxy resin and at least one thermoplastic polymer that is solid at room temperature; and applying a bitumen-based bearing course. The method permits rapid and efficient production of a roadway structure with good adhesion between the substrate and the asphalt and is suitable in particular for the restoration of asphalt coverings, which must be carried out under time pressure. The application of primer courses is not required.

A paving mixture for application to a surface and a method for the same. The mixture comprises a binding material layer applied to the surface to form a base layer on the surface, and an aggregate material layer applied on top of the binding material layer, wherein the binding material layer comprises at least 15% of the bitumen in the paving mixture by weight, the aggregate material layer contains an asphalt mixture that provides a road surface. The aggregate material layer and the binding material layer are combined on the surface within 30 seconds of application of the binding material layer.
