This invention is directed to an improved clays-stabilized bituminous emulsion composition for use as a surface coating and the like. Such an emulsion includes about 90.0-99.95 parts by weight of an aqueous bituminous emulsion and about 0.05-10.0 parts by weight of a cohesion promoting additive selected from the group consisting of amines, amidoamines and blends thereof having the structural formula X.[R(NH R'')nNH2]+Y.[R'''C(O) (NHmRIV)o] wherein X and Y are weight percentages such that X+Y=100% of the active, nitrogenous components, R is a lipophile selected from the group consisting of R'-and R'OR''-, R' is an alkyl chain having 3-26 carbon atoms, R'' is a hydrocarbon fragment 2-6 carbon atoms, n is an integer from 0-4, R''' is selected from the group consisting of an alkyl chain having 3-26 carbon atoms, and an alkenyl chain having 3-44 carbon atoms, and RIV is selected from the group consisting of [CH2CH2NH]oH, <IMAGE> and, other poly-(ethyleneamine) based products with bottoms, o is an integer from 1-6 m is an integer from 0-1, and RV is selected from the group consisting of [CH2CH2NH]nH, and H such that the resultant coating exhibits increased resistance to trafficking and water and increased cohesion. The amine is selected from the group consisting of polyamines and ether amines.
