composition and method of producing a highly viscoelastic warm blend modifier; compositions and methods of production of recycled and virgin modified warm mix asphalt concrete

摘要

The first priority of this invention is to provide the composition and the manufacturing method of a noble highly viscoelastic warm-mix modifier that can be added to asphalt binders for the purpose of reducing environmental pollution, saving natural resources by recycling RAP aggregates, reducing construction cost, and minimizing maintenance cost by extending pavement life-cycle. The highly viscoelastic warm-mix modifier may be manufactured by adding highly viscous and general purpose polymers to elastic polymers in the warm mix modifier. Warm mix additives, including waxes, oils and elastic materials, may also be introduced to the highly viscoelastic warm-mix modifier. In more details, the invention is characterized to manufacture the noble modified recycled (or regular) warm-mix asphalt concrete mixture by heating and mixing 0.5-20 weight parts of the highly viscoelastic warm-mix modifier.
