Abstract
This invention relates to the manufacture and application of uniquely suitable emulsifiers for anionic bituminous emulsions. In particular, this invention relates to emulsifiers for slow-setting aqueous emulsions suitable for use in applications where a high degree of chemical, mechanical, and rheological stability is required (such as in slurry seal applications and thixotropic industrial emulsion applications). In such applications, fine aggregate, clay, or polymer latex is mixed with the emulsion to obtain a homogenous storage-stable composite which can be applied for coatings, floorings, roofings, and as a roadway sealant.
