摘要
A composition useful as an additive for asphalt mixes, such as stone matrix asphalt and porous asphalt, comprising the mineral porcelanite and either an activating agent or amorphous silica, and asphalt mixes comprising the composition. The asphalt mixes are stable and meet performance requirements according to national standards. The asphalt mixes require less bitumen than fiber-stabilized mixes, and can be mixed for less time at a lower temperature. The asphalt mixes comprising the inventive composition are thus more economical and environmentally friendly than existing asphalt mixes.
