A fibrous material is treated with a binder solution and then heated. The binder comprises a polyester and a biopolymer, such as starch, where the polyester is a product of reaction of a polyol with an anhydride. A method for manufacturing the treated fibrous material comprises treating it with the binder solution and then heating. A cross-linking agent may be added.

The invention relates to a multi-component composition for the manufacture of polyurethane/urea cementitious hybrid system, comprising at least one isocyanate component selected from the group consisting of monoisocyanate, polyisocyanate and NCO terminated prepolymer, at least one polyol, water, catalyst, at least one acidic additive, and hydraulic binder, wherein the acidic additive is at least one selected from the group consisting of Lewis acids, acid precursors and acidic buffers and is in an amount of 0.01 to 3 wt %, based on the total weight of the composition, to the preparation thereof, and to the use of the composition for the preparation of a flooring, waterproofing, screed, grouting, primer, wall paint, roofing or coating in construction applications.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

Provided herein are an emulsified asphalt product and an emulsified coating product. Both emulsified products contain one or more rejuvenators of formula (I) or formula (X). The emulsified asphalt product is useful for improving the performance of aged or brittle resinous binders in paving applications while the emulsified coating product is similarly useful in roofing applications. Also provided herein is a treated bituminous pavement where the performance grade varies with depth.

Roofing substrates, including shingles, provide for protection of the structure it is covering as well as aesthetics. Shingles come in various types including asphalt, clay, and metal. The shingles may have a dry polymer modified cement mixture applied on top of current shingles or may be used to replace certain layers of, for example, asphalt shingles. The dry polymer modified cement may be applied before or after installation. The dry polymer modified cement may be colored to provide desired aesthetics and lower absorption of the sun's radiation (e.g., visible spectrum, infrared spectrum). The dry polymer modified cement may add minimum weight to the shingles while providing protection to the underlying substrate from environmental deterioration and weathering, thus increasing life of the shingle. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water.

A modified asphalt composition contains a bituminous component, a copolymeric thermoplastic elastomer (TPE), a high-cis homopolymeric polybutadiene rubber (BR) and a cross-linking agent. The modified asphalt composition exhibits improved low temperature flexibility (crack resistance), improved resistance to rutting (deformation) and/or improved storage stability.

The invention provides a bright white refractory roofing granule, comprising a ceramic material formed from a substantially homogenous mixture of a ceramic-forming clay, sintering material, and optionally comprising silica particles, and other potential additives, said bright white refractory roofing granule having a total solar reflectance of at least 0.80 and a Hunter Color Lvalue of at least 85.0, together with processes for making and using the same.

The asphalt formulations according to the invention include the use of post-consumer recycled materials and provide for shingle and roll roofing membranes that exhibit performance requirements of the roofing industry. The formulations provide additional benefits of less blistering compared to conventional polymer modified asphaltic formulations, and are less susceptible to external damage such as scuffing and granule loss. The post-consumer recycled materials are olefinic polymers such as polyethylene and polypropylene waxes that may be derived from, for example, feedstock from waste agricultural films, bottles, milk jugs, waste plastics, consumer bags, polyolefin plastics, and synthesized plastics.

Solar reflective roofing granules include a binder and inert mineral particles, with solar reflective particles dispersed in the binder. An agglomeration process preferentially disposes the solar reflective particles at a desired depth within or beneath the surface of the granules.

Roofing granules comprising agglomerated inorganic material, and building materials, such as shingles, that include such roofing granules. By fabricating roofing granules from agglomerating inorganic material it is possible to tailor the particle size distribution so as to provide optimal shingle surface coverage, thus reducing shingle weight and usage of raw materials. Additionally, the use of agglomeration permits the utilization of by-products from conventional granule production processes.
