A saltwater corrosion resistant hybrid composite is provided. The saltwater corrosion resistant hybrid composite coating includes at least one conductive polymer, crumb rubber, and a cured epoxy. The conductive polymer is dispersed in particles of the crumb rubber to form a network. The network is dispersed in the cured epoxy to form the saltwater corrosion resistant hybrid composite coating. A method of making of the saltwater corrosion resistant hybrid composite is also provided. A metal when coated with the resistant hybrid composite of the present disclosure is resistant to salt-water corrosion.

The present invention relates to novel rubber-modified bitumen, to improved processes for producing rubber-modified bitumen using vulcanized rubber and to the use thereof in asphalt.

A solution to the two major problems that exist today, on the one hand, by recovering the textile fibers extracted from the recycling and Processing of ELTs and, on the other hand, by providing the asphalt paving industry with an alternative mixture with superior performance to that of existing conventional mixtures. More specifically, a granulated additive based on textile fibers and rubber powder from end-of-life tires, having (a) 20% to 30% of textile fiber composed mainly of polyamide or polyester fibers, which together are of the order of 10% by weight of an ELT, (b) 20% to 50% of asphalt binder, (c) 25% to 45% of rubber powder from end-of-life tires in a fraction smaller than 0.5 mm, and (d) 3% to 10% of rubber powder from end-of-life tires in a fraction smaller than 0.18 mm. In addition, the method for obtaining same and its use in asphalt mixtures.

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 5 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, and product thereof, for modifying the surface of recycled sulfur-cured rubber via surface devulcanization that minimizes alteration of the network structure of the recycled sulfur-cured rubber, while generating strong tack between mixed recycled rubber and fresh rubber for optimal adhesion upon subsequent co-curing. In one embodiment, the surface of recycled rubber is devulcanized by treating recycled rubber with a thiol and a base dissolved in a solvent that does not effectively penetrate and only minimally swells vulcanized rubbers.
