摘要： Disclosed herein are asphalt compositions containing a block-copolymer additive, for example for use as a dispersant. In some embodiments, the asphalt compositions can include asphalt, a block-copolymer dispersant, and an SBR latex. The block-copolymers have a molecular weight exceeding 5000 g/mol with a polybutyl acrylate hydrophobic block that attaches to the asphalt particle and a sodium polystyrene sulfonate hydrophilic block for stability, wherein the block copolymer has a first block comprising of alkyl acrylate and a second block comprising units of an ethylenically unsaturated monomer with sulfonic acid groups.
The asphalt compositions can include asphalt in an amount of from 50 wt. % to 95 wt. %, based on the weight of the asphalt composition. In some embodiments, the asphalt compositions can include a styrene-butadiene copolymer in an amount of from 0.05 wt. % to 10 wt. %, based on the weight of the asphalt composition. Methods of making and using the asphalt compositions are also disclosed.

摘要： Disclosed herein are latex compositions and asphalt formulations comprising the latex compositions. In some embodiments, the latex compositions include a styrene-butadiene copolymer and polyphosphoric acid represented by the formula, Hn+2PnO3n+1, wherein n is an integer from 2 to 30. The latex composition can be used to prepare polymer-modified asphalt emulsions and hot mix asphalt compositions. The asphalt formulations can be prepared by contacting asphalt with a latex composition as described herein and a sulfur curing agent. Methods of coating a surface comprising applying an asphalt formulation as described herein to the surface are also disclosed.

摘要： Asphalt emulsions comprising asphalt present in an amount of 50% by weight or greater, based on the weight of the asphalt emulsion, an isocyanate present in an amount of 0.05% by weight or greater, based on the weight of the asphalt emulsion, and water. The isocyanate is derived from an aromatic, a cycloaliphatic, or an aliphatic isocyanate, or a mixture thereof. Preferably, the isocyanate includes methylene diphenyl diisocyanate. The asphalt emulsion can comprise one or more polyols. Methods of making the asphalt emulsions are also described.

摘要： Provided herein are asphalt compositions comprising asphalt, a carboxylated copolymer, a polyalkyleneimine, and a photoinitiator. The carboxylated copolymer present in the asphalt compositions can be a latex composition derived from a carboxylated styrene-butadiene copolymer. The carboxylated copolymer includes from 0.5% to 25% by weight carboxylic acid monomers. The carboxylated styrene-butadiene polymer and the asphalt can be present in a weight ratio of from 1:99 to 1:10. The polyalkyleneimine present in the asphalt compositions can be in an amount of greater than 0% to up to 10% by weight of the asphalt composition. The photoinitiator can include benzophenone and/or a derivative thereof. Tack coats meeting ASTM-D-977 standard comprising the asphalt compositions disclosed herein are also provided. The tack coat can have a tack-free time of 10 minutes or less. Methods of producing the asphalt compositions and tack coats are also disclosed.
