Described herein is an emulsion for use in asphalt rejuvenation applications, comprising an oil phase comprising (1) a polymerized oil comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.0 to about 5.0, and sulfur content less than about 8 wt %; and (2) an aqueous phase, comprising a surfactant. The emulsion may be incorporated into asphalt paving, roofing, and coating applications and especially aged or recycled asphalt thereby obtaining rejuvenated asphalt.

A method of resurfacing exposed surfaces of existing roads, and a resurfaced road. The method may include forming stress absorbing membrane interlayers (SAMIs) over the exposed surface of the existing road. The SAMIs may include a first layer of a binding material and a fiber material. The method may also include disposing an asphalt mixture directly over the SAMIs. The disposed asphalt mixture may cover the SAMIs. Additionally, the method may include shaping the asphalt mixture disposed over the SAMIs.

A machine for resurface existing roads. The machine may include a first group of sprayers configured to form a first layer of binding material, and a fiber material distribution component positioned adjacent the first group of sprayers. The fiber material distribution component may be configured to distribute fiber material onto the first layer of the binding material. The machine may also include a second group of sprayers positioned adjacent the fiber material distribution component. The second group of sprayers may be configured to form a second layer of the binding material over the distributed fiber material. Additionally, the machine may include a channel positioned adjacent the second group of sprayers. The channel may be configured to supply an asphalt mixture over the second layer of the binding material. Further, the machine may include a screed positioned adjacent the conduit. The screed may be positioned to contact the asphalt mixture.

The present application relates generally to bio-adhesive components isolated from bio-oil prepared from animal waste, methods of preparation of the bio-adhesive components and uses thereof. Such uses include, but are not limited to, asphalt bio-binders, bio-adhesion promoters, asphalt bio-rejuvenators, asphalt bio-extenders, bio-asphalt as well as uses in roofing, soil stabilization, crack and joint sealing and flooring adhesives.

Nano-reinforced materials hold the potential to redefine traditional materials both in terms of performance and potential applications. Dispersing carbon nanofibers (CNF) in Hot Mix Asphalt mixtures creates a piezoresistive effect and classifies the new mixture as a smart material. The current invention uses the electromechanical capabilities of carbon fibers to sense its own strain by way of electrical resistivity to develop a Self-sensing Piezoresistive Hot Mix Asphalt.
