A void filling asphalt emulsion and a method of using the void filling asphalt emulsion to fill voids below the surface of an asphalt pavement. The void filling emulsion is prepared by forming a base asphalt emulsion having about 45 to 75 wt. % of an asphalt content, and combining the base asphalt emulsion with a surface tension reducing solution to produce a void filling asphalt emulsion that has about 25 to 50 wt. % of an asphalt content. When applied to an asphalt pavement the void filling emulsion penetrates into the asphalt pavement and fills voids in the asphalt pavement. The void filling emulation further being water resistant so as not to be washed off a pavement surface by water after being applied to the pavement.

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.

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.

Described herein is a polymerized biorenewable, petroleum based, previously modified, or functionalized 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 ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

A method of forming an asphalt binder includes the steps of: providing a liquid binder base housed in a feeding tank; providing a plurality of unprocessed granules of a waste plastic material housed in a hopper; pumping the liquid binder base into a wetting tank; augering the plurality of unprocessed granules of the waste plastic material into the wetting tank; mixing the liquid binder base and the plurality of unprocessed granules of the waste plastic material to form a blended binder that includes 5 percent to 40 percent by volume of the waste plastic material and 60 percent to 95 percent by volume of the liquid binder base; pumping the blended binder into a storage tank; and mixing the blended binder at a temperature of 325° F. to 350° F. for a duration of 10 minutes to 30 minutes to form the asphalt binder.

The present application discloses compositions and methods for improving or enhancing the paving or re-paving of asphalt to road surfaces comprising the addition of the composition to the asphalt.

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.

Aqueous base- or acid-stabilized emulsions are provided for use on a pavement surface, and for use in an aqueous priming base emulsion that is used for priming a pavement surface. Any of the emulsions can be applied to a pavement surface to form a primed pavement surface, and then cured so that the pavement is available for use in preparing a pavement.
