Claim:
1. A method of reducing voids in asphalt pavement joints defined between first and second side-by-side adjacent asphalt paving passes which method comprises: providing a joint composition that comprises: applying a band of the joint composition to a surface upon which an asphalt pavement joint will be formed between first and second side-by-side adjacent asphalt paving passes; forming first and second side-by-side adjacent asphalt paving passes on the surface using hot mix asphalt so that a joint defined between the first and second side-by-side asphalt paving passes is aligned over the band of the joint composition, allowing the joint composition to migrate upward into the hot asphalt paving passes so as to reduce air voids in the hot asphalt paving passes in the area of the joint to 7% or less, wherein the at least one of fumed silica and fumed alumina imparts lateral flow resistance and a non-tacky characteristic to the void reducing asphalt membrane composition.
