A rapid set microsurfacing system which comprises 36% water, 2% of the quaternized or unquaternized emulsifier, 1.5% acid (HCl), 56.5% asphalt residue, and 4% latex polymer [1.5% water and 2.5% rubber]. The quaternized or unquaternized emulsifier comprising an amidoamine and imidazoline mixture prepared from the combination of a tall oil fatty acid rosin mixture with a rosin content between 8 to 40 percent and a polyamine of either ethylenediamine, diethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylene pentamine, or aminoethylethanolamine. The break control agent used can be a hydrophilic, alkylated vinylpyrrolidone polymer (commercially available as Ganex TM P-904 Polymer); polypropylene glycol; polysiloxane compounds such as trimethylsiloxy terminated polydimethylsiloxanes, silanol terminated polymethylsiloxane, T-structure polydimethylsiloxanes with styrene, vinyl chloride, ethylene, propylene or butadiene; the saponified or unsaponified microsurfacing emulsion or a combinations of these chemicals.
