Recycled medium temperature modified asphalt mixture from recycled waste resources

摘要

The present invention relates to a circulating medium-temperature reformed asphalt mixture in which waste resources such as waste plastics, waste glass, waste asphalt, and sulfur by-products are recycled. Prepare the aggregate to be used, crush the waste plastic with a polymer material modifying additive, and a pelletized medium-temperature additive including paraffin wax, EB wax, stearic acid, oil, and slaked lime mixed with asphalt in a dry or wet manner to produce a binder In order to prepare and use the binder having medium temperature modifying properties with the aggregate used in a dry or wet method, 30 to 50 parts by weight of coarse aggregate crushed into 10 to 40 mm as natural aggregate, and 1 to 10 20 to 60 parts by weight of fine aggregate crushed into mm; As recycled recycled aggregate, 10-50 parts by weight of waste asphalt crushed to 1-13 mm, and 10-40 parts by weight of waste glass material crushed to 1-5 mm; As the waste glass material, a transparent material is used, and 2 to 10 parts by weight of a filler material for asphalt pavement is prepared, including 2.3 to 4.0 parts by weight of new asphalt, and 2.0 to 2.0 to old asphalt of recycled aggregate for asphalt. To 3.0 parts by weight, 2.3 to 3.0 parts by weight of a medium temperature additive made of sulfur polymer generated in the petroleum refining process; prepare a modified medium temperature binder (A2) including; The modified additive of the polymer material formed from the used plastic waste is 2.0 to 8.0 parts by weight based on the weight of the asphalt mixture; The waste plastic forms scratches on the surface to secure a wider specific surface area of the crushed waste plastic in order to increase the adhesion with the binder including asphalt, and the waste plastic material is a low-density polyethylene recycled material, the modified medium temperature It is composed by further mixing a binder (A2) with a functional additive made of any one or more of antioxidants, antioxidants, zeolite, and process oil, and waste tire fine powder (CRM) with modified aging properties, and the waste tire fine powder ( CRM) is formed of 1 mm or less raw rubber fine powder regenerated from waste tires for vehicles, and the modified medium temperature binder (A2) is mixed with the aggregate (A1) to be used.
