The invention relates to the field of road construction materials, and it is intended to improve the quality of road surfaces, roofing and insulating materials based on bitumens, which is achieved by improving the quality of bitumens with the help of using modified crumb rubber—a disposal product of used automotive and tractor tires, in particular, the invention relates to a low-temperature method for manufacturing modified crumb rubber to improve the quality of bitumens and asphalt concretes and to the technology for mixing it with bitumen, for the purpose of creating a uniform material that is not prone to destruction during long-term storage. The present invention consists in the development of a new method for manufacturing the modified crumb rubber, comprising preparing a mix from the following components: crumb rubber from used automotive and tractor tires with a particle size of up to 1 mm—50-65 wt. %, oxides and/or hydroxides of alkaline-earth metals—10-20 wt. %, petroleum oil of solvent refining with the viscosity of from 0.05 to 1.5 Pa*s at 60° C.—20-30 wt. %, an amine type antiageing agent—a heterocyclic nitrogen-containing compound—0.1-2.0 wt. %; mixing the components of the resulting mix with a shock-shear load on the material in a mixer-activator at a temperature of 80-120° C.; and further cooling the resulting mix to a room temperature.

Asphalt binders are modified using fractional products from waste tire pyrolysis, using an initial step of i) at least partially pyrolyzing, separately from such asphaltic binder, whole rubber articles or size-reduced rubber particles to provide one or more pyrolyzed rubber fractions including a pyrolyzed oil fraction having a selected minimum initial boiling point or flash point, and ii) removing some or all polycyclic aromatic hydrocarbon (PAH) compounds from such pyrolyzed oil fraction to provide a reduced-PAH and preferably translucent pyrolyzed oil fraction that may be combined with an asphaltic binder to provide a modified asphalt composition.

A seawall comprising a base with a top, a plurality of extensions on the top of the base, and an adhesive or sealant securing the extensions to the base. Each extension comprises a plurality of spaced apart rubber poles extending generally in a direction horizontal to the sea floor, and an outer rubber covering surrounding the poles. A method of increasing the height of a seawall comprising the steps of placing a plurality of the extensions on top of the seawall with the poles extending substantially parallel to the sea floor, and securing the extensions to the top of the seawall.

Described herein is a method for preparing a molded rubber product comprising a printed label that is integrally molded into the molded rubber product as part of the normal molding process in order to ensure the label becomes an integral part of the final molded rubber product. The printable label may be composed of a rubber based reflective sheeting.

The present invention relates to a devulcanized rubber obtained by mixing a devulcanizing agent having an alkylamide group and a vulcanized rubber. The devulcanizing agent is preferably an amide compound of an alkylamine having 12 or more carbon atoms. The present invention also relates to a rubber composition comprising the devulcanized rubber. The rubber composition preferably contains 1 to 30 parts by mass of the devulcanized rubber per 100 parts by mass of a total amount of an unvulcanized rubber component in the rubber composition.

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.
