Components of superior high viscoelastic warm mixing modifier and method for producing the same, and components of virgin and recycled modified warm mixed asphalt concrete mixture and method for producing the same

摘要

The first priority of the present invention is to reduce the environmental pollution, save natural resources by recycling RAP aggregates, reduce construction costs, and minimize maintenance costs by extending the pavement life cycle. It is to provide an excellent and highly viscoelastic warm mixing modifier component to be added and a production method. High viscoelastic warm mix modifiers are made by adding a high viscosity, general purpose polymer to an elastic polymer in a warm mix modifier. Warm mixing additives including waxes, oils and elastic materials are also introduced into the high viscoelastic warm mixing modifier. More specifically, the present invention provides an excellent modified recycled (or normal) warm mixed asphalt concrete mixture by heating and mixing 0.5-20 parts by weight of a high viscoelastic warm mixed modifier. It is characterized by manufacturing.
