A system for processing material, including at least one microwave generator, at least one microwave guide operatively connecting the at least one microwave generator to at least a first conveyor unit, and the first conveyor unit provided in a first housing that comprises at least one opening configured to receive microwave energy via a first microwave guide. The first conveyor unit is configured to receive and process a quantity of material, which includes heating the material to a first temperature by applying microwave energy to the material within the first housing.

Microwave heating system with suppression tunnel and related features

The present invention provides a functionally dry warm mix asphalt binder composition modified with lubricating agents or additives that can be mixed with aggregate and compacted at temperatures substantially below asphalt binder compositions that do not contain the disclosed lubricating additives.

Warm mix asphalt binder compositions containing lubricating additives

Disclosed are asphalt binder compositions and methods for making such compositions with pure sterol:crude sterol blends. The sterol blends improve various rheological properties.

Sterol blends as an additive in asphalt binder

Pavement aging can be reduced by applying to an asphalt-containing pavement a topcoat layer or a surface treatment containing asphalt binder with sterols.

Sterol additive in asphalt pavement

Pavement aging can be reduced by applying to an asphalt-containing pavement a topcoat layer or a surface treatment containing asphalt binder emulsion with sterols.

Asphalt emulsion surface treatment containing sterol

Disclosed are binders and methods for making such binders with crude sterols. The crude sterols improve various rheological properties of the binders. The disclosure provides a method for slowing the aging rate of aged asphalt binder comprising adding a crude sterol to an asphalt binder, wherein the asphalt binder comprises both virgin asphalt binder, and reclaimed asphalt binder material comprising asphalt pavement (RAP), asphalt shingles (RAS) or combinations of RAP and RAS.

Crude sterol as an additive in asphalt binder

Disclosed are asphalt and asphalt binders and methods for making such compositions with sterols. The sterols improve various rheological properties. Also disclosed are methods of determining the changes or improvements of various rheoloical properties.

Method for identifying the extent of aging in an asphalt

Disclosed are asphalt binder compositions that contain at least one sterol or stanol additive, or blends of sterols and stanol additives, wherein the sterol or stanol additive is derived from an animal waste or manure source such as swine manure. These sterol and stanol-based additives improve various rheological properties of the asphalt binder compositions showing reduced and/or mitigated aging characteristics.

Use of sterols from animal waste as an additive in asphalt binder

Cold-in-place asphalt recycling is disclosed. A foamed asphalt may be produced by injecting water and optionally compressed air into a hot asphalt stream. A lubricating surfactant may be added to the hot asphalt stream to improve performance. The foamed asphalt may be mixed with reclaimed material to provide a uniformly coated paving material that can compacted to a desired density.
