Abstract
Anionic Emulsions of asphalt, bitumen, or tar which may optionally contain a latex of a rubbery polymer may be set using a destablizing system comprising either an alkali silicofluoride in the presence of a sulfamate or a mixture of an amine in the presence of a divalent metal ion. The setting time for such emulsions can be reduced to less than half an hour.
