A composition for sealing and resurfacing a road surface includes a first material having at least a first emulsified asphalt, wherein the first material is applied to the road surface. The composition also includes a second material having a second emulsified asphalt and a driving surface material. The second material is applied to the first material such that the first material and the second material co-cure as a unified material.

A building product having a body including a covered region including granules, at least 18 wt % of the granules include reclaimed granules having an average residual asphalt of at least 0.1 wt % for a total weight of the reclaimed granules.

A hybrid additive for use in construction materials such as asphalt and concrete. The additive includes a plastic or polymer material, and one or more of fibers, pozzolans, nano-carbon tubes, glass, recycled asphalt shingles (RAS), liquid anti-strip, hydrated lime, rejuvenators, cementitious material, and ground tire rubber. Also disclosed are hybrid composite materials useful as paving and building materials, and methods of making the same. The hybrid additives were found to improve the performance of the asphalt and concrete mixtures by increasing bonding and strength within the mixture, thereby lowering the costs and increasing the performance and useable life of structures formed using the mixtures.

The current invention concerns composition comprising bitumen, one or more plasticity modifying agent(s), and lignin, as well as methods and uses related to such compositions. In particular, compositions are disclosed with improved properties, such as mixing properties.

The present invention relates to polymer-modified bitumen, to a process for production thereof and to the use thereof for asphalt.

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.

An asphalt-based sealcoat composition comprising high levels of titanium oxide particles is provided. In some embodiments, a highly solar reflective asphalt-based sealcoat composition comprising high levels of titanium oxide particles is provided. In some embodiments, an asphalt-based sealcoat composition capable of reducing pollutants comprising high levels of titanium oxide particles is provided. In some embodiments, methods for preparing asphalt-based sealcoat compositions as well as their application to asphalt surfaces is provided.

The present invention relates to novel bitumen-containing mixtures, to a method for the production thereof and to the use thereof.

A coating system and related methods for an airfield surface or a roadway is described. The coating system may include a stable cationic emulsion for application to the airfield surface or the roadway. The stable cationic emulsion may include a) an asphalt blend comprising gilsonite, wherein the gilsonite is modified to possess a positive charge, b) one or more polymers, and c) one or more surfactants not including a cationic surfactant. The coating system may also include a fine aggregate material for application to the stable cationic emulsion applied to the airfield surface or the roadway.
