PRISM Thermoplastic Rubber (PTR) is a novel, composite rubber material technology principally compounded from EOL, ambient ground, whole tires through the management of a unique process governed by the application of advanced, quantum field physics. The value from this technology is to provide a virgin-material-analog that may be readily integrated at high ratio, into new tire construction using conventional tire chemistry and manufacturing techniques resulting in a sustainable and significant, positive cost-benefit ratio as compared to current tire manufacturing economics.

A method of making a tire tread includes mixing a tire tread compound including a virgin rubber component and a reclaimed rubber component, forming a green sheet from the tire tread compound, and curing the green sheet to form a cured tire tread. The reclaimed rubber component may have a Mooney viscosity (ML (1+4) @ 100° C.) of greater than 65. The reclaimed rubber component may also have a crosslink density that is between 20 and 50% of the crosslink density of the reclaimed rubber prior to reclaiming.

The present invention relates to asphalt compositions. The present invention provides for a sulfur rubber asphalt binder composition that includes a base asphalt having a softening point, elemental sulfur, and a recycled crumb rubber material. The crumb rubber material is combined with the base asphalt and the elemental sulfur to create the sulfur rubber asphalt binder composition. The crumb rubber material is present in the sulfur rubber asphalt binder in an amount effective to increase the softening point as compared to the softening point of the base asphalt.
