    Abstract: Methods for reducing asphalt pavement thickness, for fabricating asphalt paving material with increased aggregate-to-aggregate contact points, and for fabricating asphalt paving materials with improved low temperature cracking performance are provided. A method for reducing asphalt pavement thickness includes combining a base asphalt, an oxidized polyolefin, and an aggregate to form an asphalt paving material. A layer of the asphalt paving material is deposited on a substrate layer and compacted to a thickness that is less than a thickness of a compacted asphalt paving material formed of the aggregate and the base asphalt with no oxidized polyolefin while achieving the same amount or less of high temperature rutting than the compacted asphalt paving material formed of the aggregate and the base asphalt with no oxidized polyolefin.
