1. An asphalt composition comprising:
- an asphalt binder;
an elastomeric polymer;
a wax modifier; and
a filler selected from fumed silica and fumed alumina,wherein the composition is formulated to include 85 to 97 wt. % of the asphalt binder,1 to 6 wt. % of the elastomeric polymer,1 to 5 wt. % of the wax modifier, and1 to 10 total wt. % of the filler selected from fumed silica and fumed alumina.

Abstract
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.
