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.

The present invention relates to an asphalt composition containing asphalt, cellulose, and a polyester.

An object of the present invention is to provide a method for constructing a base course without rolling compaction, in which a compacting step by rolling compaction and further adjustment of the water content of the mixture to the optimum water content are not necessary, and to provide a mixture for base course, which enables the said method. The above object is attained by providing a method for constructing a base course without rolling compaction, which comprises a step of obtaining a mixture by mixing an aggregate, an asphalt emulsion, and a cement, wherein the mixture is in a high-water-content state in which a water content of the mixture is above an optimum water content of the aggregate, and a step of spreading the mixture; and which does not comprise a step of rolling compaction, and by providing a mixture for a base course, comprising an aggregate, an asphalt emulsion, and a cement, wherein the mixture is in a high-water-content state in which a water content of the mixture is above an optimum water content of the aggregate.

A bituminous mastic includes:—from 0.5% to 25% by mass of at least one hydrocarbon oil, the total content of paraffinic compounds of which, measured according to the ASTM d2140 method, is greater than or equal to 50% by mass, and preferably greater than or equal to 60% by mass, relative to the total mass of the oil,—from 15% to 60% by mass of bitumen,—from 20% to 60% by mass of fillers, and—at most 14%, by mass of at least one polymer, preferably chosen from elastomers, relative to the total mass of bituminous mastic. A method for preparing such a bituminous mastic and to the uses thereof, in particular in certain road and/or industrial applications.

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.

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.

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.

The Present disclosure is related to hot-mix asphalt (“HMA”) which open new price/performance areas to asphalt cement concrete (“ACC”) pavement. Equivalent-performing pavement may be made at lower cost, or higher-performing pavement may be made at equivalent-to-prior-art cost. The amendments, recycled asphalt pavement (“RAP”, and including recycled asphalt shingles [“RAS”]), and reinforcing fiber (aramid fiber) may be adjusted as described herein to achieve a desired price/performance target.
