It`s a Emulsion bitumen CSS-1 cationic slow setting asphalt emulsion produced by the patented SMEP process also Emulsion bitumen is sutaible for road. however producer make The base asphalt for emulsification from specially  crude oils via carefully refining processes.  by the way Emulsion bitumen CSS-1 components are carefully selected and balanced, according to formulations.

Bitumen Emulsion have being developed and exponentially increased sinned they were created in 1900. Estimated presently at 20% of the global bitumen use and Emulsion bitumens are basically an O/W – Oil on Water solution – A dispersion of bitumen particles on water, stabilized with the addiction of surfactants – Surface active agents – or most commonly known as emulsifiers, that will permit the bitumen to de diluted in water, however They primarily using for tack coats for use in between hot mix asphalt layers and prime coats for thin hot mix surfacing layers or a chip seal pavements.  any way Emulsion Bitumen devid into 3 categories; 

Non_ionic with neutral globules 

cationic with positively charged globules

Anionic with positively charged globules
