Provided herein is an asphalt membrane emulsion for reducing voids in an asphalt joint that includes asphalt, an asphalt modifier, mineral filler, an emulsifier, and water. Provided herein is a method of making an asphalt membrane emulsion, the method including: forming a first phase; forming a second phase; pumping the first phase and the second phase into a colloid mill; and mixing the first phase and second phase into the colloid mill to form the asphalt membrane emulsion. The first phase includes asphalt, asphalt modifier, and mineral filler. The second phase includes water and an emulsifier. A method of applying an asphalt membrane emulsion to fill a crack is also provided.

Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, 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.

Provided is an asphalt binder composition, and more particularly, an asphalt binder composition capable of improving mixability between an asphalt binder and an aggregate, and compactibility and water resistance of an asphalt paving mixture. More particularly, the present invention relates to an asphalt binder composition capable of being used in hot mix asphalt for improving workability and/or stripping-resistance, warm-mix asphalt, recycling of reclaimed asphalt pavement, or the like.

The present invention relates to a thermoplastic block copolymer comprising at least one PA block and at least one PB block. The PA block represents a polymer block comprising one or more units of monomer A, and the PB block represents a polymer block comprising one or more units of monomer B. Monomer A is a vinyl, acrylic, diolefin, nitrile, dinitrile, acrylonitrile monomer, a monomer with reactive functionality, or a crosslinking monomer. Monomer B is a radically polymerizable triglyceride or mixtures thereof, typically in the form of a plant or animal oil. The present invention also relates to a method of preparing a thermoplastic block copolymer or novel thermoplastic statistical copolymers by polymerizing a radically polymerizable monomer with a radically polymerizable triglyceride or mixtures thereof via reversible addition-fragmentation chain-transfer polymerization (RAFT), in the presence of an free radical initiator and a chain transfer agent.

An adhesive bituminous sheath for building includes bitumen and an adhesivizing additive mixed with the bitumen, wherein the adhesivizing additive is an aliphatic and cycloaliphatic resin.

Compositions and methods for reducing the foul odors of a hydrocarbonaceous material such as asphalt comprise the addition of an odor reducing amount of a reducing carbohydrate and/or a soluble zinc compound. The reducing carbohydrate may be a monosaccharide, oligosaccharide or polysaccharide, including a starch; and it may be used as a sole odor reducing agent or in combination with soluble zinc compounds and/or other odor reducing compounds.

The present invention refers to a multifunctional asphalt additive composition comprising a hydrocarbon base oil, an adhesion promoter, and naturally occurring resins. In particular, the hydrocarbon base oil comprises paraffinic or aromatic compounds, the adhesion promoter comprises aromatic, amine, acrylic, and straight or branched chain organosilane derivatives, and the naturally occurring resins comprise tannins, terpenes, and rosin. The multifunctional additive composition of the present invention is useful in the manufacture of asphalt mixtures, as a rejuvenation agent, in the recycling of asphalt mixtures, or as an additive to provide or improve one or more of the properties of low quality asphalts or those that do not meet the standards required for certain applications.

The present invention relates to a thermoplastic block copolymer comprising at least one PA block and at least one PB block.
