A method of recycling rubber includes pre-treating vulcanized ground rubber to prevent the vulcanized ground rubber from encountering significant additional crosslinking during co-vulcanization with fresh rubber compound, and promoting better bonding between the vulcanized ground rubber and the fresh rubber compound. The ground vulcanized rubber can be coated with a layer of non-vulcanized rubber that includes cure inhibitors or other ingredients dispersed within the layer to aid in the coating process and/or co-vulcanization of the vulcanized ground rubber and fresh rubber compound. The vulcanized ground rubber can also be pre-treated with a mixture of at least one chemical curing agent inhibitor and a solvent capable of solubilizing the chemical curing agent inhibitor and dispersing the curing agent inhibitor within the vulcanized ground rubber.

In various embodiments, the graphene-based carbon material comprises graphene comprising up to 15 layers, carbon aggregates having a median size from 1 to 50 microns, a surface area of the carbon aggregates at least 50 m.sup.2/g, when measured via a Brunauer-Emmett-Teller (BET) method with nitrogen as the adsorbate, and no seed particles.

A method and system for generating a tire rubber asphalt compound is described. The method includes receiving an asphalt compound and heating the asphalt compound to approximately 320 F. to 420 F. The method then proceeds to add tire rubber to the asphalt compound. The asphalt compound and the scrap tire rubber are mixed for approximately 60 minutes to 360 minutes during heating to approximately 525 F. to 700 F. to generate the tire rubber asphalt compound. The tire rubber asphalt compound is then cooled.

A method of manufacturing zoned webs can include providing a substrate and transferring the substrate in a machine direction. The method can include modifying the substrate to include a plurality of lanes to provide a modified substrate. The plurality of lanes can include a first lane and a second lane. The first lane can include a first zone and a second zone. The first zone can include an open area greater than an open area of the second zone. The second lane can include a third zone and a fourth zone. The third zone can include an open area greater than an open area of the fourth zone. The first lane and the second lane can be formed such that the first zone in the first lane is staggered in the machine direction from the third zone in the second lane. The method can also include slitting the modified substrate between adjacent lanes in the plurality of lanes to provide zoned webs.

An organometallic compound is incorporated into a vulcanized rubber matrix. A tunable, multi-phase copper sulfide lattice is compounded within an existing sulfur cross-linked morphology, as in crumb rubber obtained from recycled tires or other vulcanized rubber, whereby thermotropic properties of the rubber matrix are modulated. The process involves breaking of sulfur-sulfur and/or sulfur-carbon bonds through action of the carbon sulfide. The resulting rubber is suitable for use in applications typically utilizing virgin rubber, such as new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications. In other embodiments, an organometallic compound comprising iron acetate or alkaline earth metal acetate is incorporated into the vulcanized rubber matrix.
