Abstract:Using different SBR latex to produce modified asphalt emulsionComparison of the influence of SBR brand and dosage on technical indexes of modified emulsified asphalt, get the influence of SBR latex content on the extension degree, softening point and viscosity toughness of asphalt emulsion residue, recommend the latex brands and latex dosage. It provides reference for the application of SBR latex emulsified asphalt in Engineering
