VOID REDUCING ASPHALT MEMBRANE COMPOSITION, METHOD AND APPARATUS FOR ASPHALT PAVING APPLICATIONS

摘要

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.

1. An improved longitudinal asphalt pavement construction joint area for construction of pavements that comprises a first substrate that defines an existing pavement surface portion, a hot mix application portion and a void reducing asphalt membrane composition provided between the first substrate and the hot mix application, the void reducing asphalt membrane composition comprising:
an asphalt binder; an elastomeric polymer; and a wax modifier.
