Quick setting anionic bituminous emulsions
A bituminous emulsion is described comprising: (a) from about 50% to about 70% by weight of non-coal tar bitumen; (b) from about 0.1% to about 3% by weight of an emulsifier which is the amine salt of an alkylbenzene sulfonic acid in which the alkyl contains from about 8 to about 16 carbon atoms. The salt-forming amine is selected from amines having the formula: wherein R/sub 1/ is selected from the group consisting of aminoalkyl and monohydroxyalkyl radicals containing from 1 to about 6 carbon atoms and R/sub 2/ and R/sub 3/ are each selected from the group consisting of hydrogen, alkyl, aminoalkyl and monohydroxyalkyl radicals containing from 1 to about 6 carbon atoms and wherein the molar ratio of alkylbenzene sulfonic acid to amine in the amine salt is 1:1; and (c) from about 30% to about 50% water, the composition having a pH of from about 2.5 to about 10.
