Abstract: A method and system is provided for fabricating an elastomeric article, and comprises the steps of: providing a predetermined quantity of a comminuted rubber composition; heating the comminuted rubber composition to a predetermined processing temperature which effects at least a partial devulcanization thereof; forming a homogeneous dispersion by combining with that rubber composition a predetermined quantity of an additive composition; mixing with the homogeneous dispersion a predetermined quantity of a plastic composition and heating the resulting mixture to a predetermined extruding temperature to form a viscous compound composition; and, mechanically processing the viscous compound composition to form the elastomeric article.

Abstract: This invention provides for a method of producing an asphalt product which includes initially shredding scrap tires within a shredder system (14) where at least partially vulcanized rubber composition is formed into particulates less than approximately 2.0 mm in dimension. Metal is removed from the scrap tires and the resulting composition leaving the shredder system (14) is mixed in particular weight percentages with a chemical composition for insertion into a masticator system (28) which includes a first zone (42), a second zone (44), and a third zone (46). The masticator system (28) heats the composition entering to a temperature approximating 485.degree. F. in the first zone (42). The composition is then cooled to a temperature within the approximating range of 230.degree. F.-250.degree. F. in second zone (44) and then slightly re-heated to a temperature within the range of 290.degree. F.-350.degree. F. in the third zone (46).

Abstract: A process for producing thermoplastic resin products where granulated or particulate vulcanized rubber is sprayed by a heated heavy paraffin distillate composition to form a first intermediate mixture composition. The first intermediate mixture composition is passed through a heating chamber on a conveyor and combined with particulate thermoplastic scrap material in an approximating weight percentage of 30% thermoplastic material to 70% first intermediate mixture material. The combination forms a second intermediate mixture composition which is masticated in a masticator and extruded through a single screw feed mechanism for pelletizing and producing thermoplastic resin products which are useful for molding.
