Title (EN) LATEXES CONTAINING POLYPHOSPHORIC ACID FOR ASPHALT MODIFICATION
(FR) LATEX CONTENANT DE L'ACIDE POLYPHOSPHORIQUE POUR LA MODIFICATION DE L'ASPHALTE
Abstract:
(EN) 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.
(FR) La présente invention concerne des compositions de latex et des formulations d'asphalte comprenant lesdites compositions de latex. Dans certains modes de réalisation, les compositions de latex comprennent un copolymère de styrène-butadiène et de l'acide polyphosphorique représenté par la formule, Hn+2PnO3n+1, dans laquelle n représente un nombre entier de 2 à 30. La composition de latex peut être utilisée pour préparer des émulsions d'asphalte dont le polymère a été modifié et des compositions d'asphalte mélangé à chaud. Les formulations d'asphalte peuvent être préparées en mettant en contact l'asphalte avec une composition de latex telle que décrite dans la présente description et un agent de durcissement à base de soufre. L'invention concerne également des procédés de revêtement d'une surface consistant à appliquer, sur ladite surface, une formulation d'asphalte telle que décrite dans la présente description.
