Abstract
A process for effectively mechanically disrupting fiber pellets produced from waste carpet material into their individual strands and for insertion and uniform distribution of such fibers through congealable materials such as asphalt and concrete, thereby providing improved physical properties to the resultant solids and, by providing a use for such waste carpeting, minimizing their deposition in landfills.
Claims24
A process for providing congealable materials having fiber reinforcement and aggregate content, said process comprising the steps of:
- a. providing a source of aggregate material;
- b. providing a source of fiber, said fiber having a primary source selected from the group consisting of:
- waste carpeting and waste textiles;
- c. providing a source of congealable material;
- d. providing means for mixing granular materials and for mixing together granular and liquid materials;
- e. dispensing a first quantity of aggregate material into said mixing means;
- f. dispensing a first quantity of fiber into said mixing means;
- g. mixing together said fiber and aggregate whereby the fiber is ground and distributed throughout said aggregate, thereby forming a first mixture and
- h. dispensing and mixing a first quantity of congealable material into said first mixture whereby said aggregate and fiber are distributed throughout the congealable material, thereby forming a second mixture comprising congealable material having fiber reinforcement derived principally from waste carpet and aggregate content distributed throughout.
A process for providing fiber content in hot-mix asphalt materials having aggregate content, said process comprising the steps of:
- a. providing a source of aggregate;
- b. providing a source of fiber in pellet form, said fiber having a primary source selected from the group consisting of:
- waste carpeting and waste textiles;
- c. providing means for mixing granular materials and for mixing together granular and liquid materials;
- d. providing a source of a hot asphalt liquid;
- e. dispensing a first quantity of aggregate and a first quantity of fiber pellets into said mixing means;
- f. operating said mixing means whereby said first quantity of fiber pellets are ground and distributed throughout said aggregate, thereby forming a first mixture;
- and
- g. dispensing and mixing a first quantity of hot liquid asphalt into said first mixture whereby said aggregate and fiber are distributed throughout the hot asphalt thereby forming a second mixture comprising hot liquid asphalt having fiber reinforcement derived principally from waste carpet and aggregate content distributed throughout.
A process for providing fiber content in cementitious materials having aggregate content, said process comprising the steps of:
- a. providing a source of aggregate;
- b. providing a source of fiber in pellet form, said fiber having a primary source selected from the group consisting of:
- waste carpeting and waste textiles;
- c. providing means for mixing granular materials and for mixing together granular and liquid materials;
- d. providing a source of cementitious powder;
- e. providing a source of water;
- e. dispensing a first quantity of aggregate and a first quantity of fiber pellets into said mixing means thereby forming a first mixture;
- f. operating said mixing means whereby said first quantity of fiber pellets are ground and fibers therefrom distributed throughout said aggregate;
- g. dispensing and mixing a first quantity of water into the mixer thereby forming a second mixture.
