Abstract: A polymer-modified emulsion used for micro surfacing paving applications that results in a durable paving composition. The residue from the emulsion exhibits a resistance to cracking and an overall reduction in reflective cracking.

Abstract: An asphalt mixture comprising an asphalt binder, wherein the asphalt binder comprises at least one of a virgin asphalt binder, a reclaimed asphalt binder material comprising asphalt pavement (RAP), or a reclaimed asphalt binder material comprising asphalt shingles (RAS) and an anti-aging agent having a hydroxyl value of greater than about 25 mg KOH/g.

Abstract: Formulations and methods of making and using two emulsions, one emulsion having a rejuvenating agent and another emulsion having an asphalt phase. The two emulsions may be serially applied or blended together to form a dual emulsion for various deteriorated pavement surface treatments. The two emulsions may be used with a recycled asphalt product, either being mixed with the recycled asphalt product or serially applied to the recycled asphalt product. The two emulsions when blended together may form a dispersion having different phases with different setting times. The surfactant in the rejuvenating emulsion may be faster setting for a preferred initial break and better interaction with the pavement product, while the surfactant in the asphalt emulsion may break more slowly and provide more time to combine with the rejuvenated binder and fully coat the deteriorated asphalt product, and any virgin aggregate added to the mix.

Abstract: We disclose a method of making an asphalt composition containing large quantities of ground tire rubber. Over 20% GTR by weight can be used in the asphalt composition without the GTR settling out. The method comprises a series of heating and blending and using a GTR stabilizer.

Abstract: In one aspect of the invention, an asphalt recycling machine has a passageway in communication with a fluid source secured to a motorized vehicle and a fogging nozzle. The fogging nozzle is connected to an underside of the motorized vehicle. The fogging nozzle is also proximate a rotary degradation element connected to the underside of the motorized vehicle. The rotary degradation element has an axis of rotation nonparallel with a paved surface.

Abstract: A method for recycling a paved surface includes the steps of providing a motorized vehicle adapted to traverse a paved surface; providing the motorized vehicle with a plurality of degradation elements, a plurality of foaming elements and a plurality of compacting elements; each plurality being attached to a carriage slidably supported by a bearing surface of an underside of the motorized vehicle; degrading the paved surface with the plurality of degradation elements as the vehicle traverses the paved surface; foaming rejuvenation material by the plurality of foaming elements into the degraded surface as the surface is being degraded; and compacting the degraded surface and the rejuvenation material into a new surface with the plurality of compaction elements as the foaming elements continue to foam rejuvenation material into the degraded surface.

Abstract: In one aspect of the present invention, a paved surface reconditioning system has a vehicle adapted to traverse a paved surface. The vehicle having a press plate with a working surface having plurality of nozzles disposed therein. At least one of the nozzles has an inner diameter less than 1 mm. A fluid passage may connect the nozzle to a reservoir. The reservoir and fluid passage have a volume and a pressurizing mechanism in communication with the volume and being adapted to pressurize at least a portion of the volume.

Abstract: In one aspect of the invention, a method for reconditioning a paved surface includes the steps of providing a vehicle adapted to traverse the paved surface; providing a layer of loose aggregate on an underlayer by degrading the paved surface with a degradation element attached to the vehicle; adding a foaming agent to the layer of loose aggregate on the underlayer; and coating a total aggregate surface area by mixing hot asphalt into the loose aggregate and allowing the foaming agent to expand the asphalt.
