Technical Examples
  1. A method of selecting a bituminous emulsion with enhanced performance for paving is provided. This method includes selecting polymer modified bitumen with a penetration value of about 25 to 450 dmm at 25° C. and selecting one or more emulsifiers comprised of at least about 5% by mass of a cationic nitrogenous compound selected from compounds having a carbonyl carbon atom bonded to a nitrogen atom, compounds having a carbon atom double bonded to a nitrogen atom, or combinations thereof based on the total mass of the selected emulsifier. Each selected emulsifier is reacted with a carboxylic acid to create one or more carboxylate salts. Each carboxylate salt created from a different proposed emulsifier separately is mixed with the bitumen to form one or more proposed bituminous emulsions. The coalescence of each proposed bituminous emulsion is measured using a rheology test, and a bituminous emulsion of the composition described above is chosen for paving a surface based on its coalescence properties.
