Bitumen Emulsion K1-70

General Description of Cationic Bitumen Emulsion K1-70

Bitumen Emulsion is made up of three basic ingredients which include Bitumen, an emulsifying agent and water. Bitumen Emulsion K1-70 containing minimum 67% Bitumen, is commonly used for Tack-Coating. It is a medium viscosity cationic rapid-set bitumen emulsion used mainly for tack coating in normal overlay and patching work. Bitumen K1- 70 bitumen emulsion can also be used in grouting. Bitumen Emulsion K1-70 cationic bitumen emulsion is made according to KS 02-769: 1990 standard.

Uses of Cationic Bitumen Emulsion K1-70

Treatments and seals:

  • Single surface treatment
  • Multiple surface treatment
  • Sand seal

Penetration macadam

  • Small voids

* K1-70 may be used as a tack coat in special cases where night construction or high humidity exists.

Cationic emulsions may be used at ambient temperatures with aggregates, which need not be completely dry. Emulsions are less hazardous to use and can be applied in a wider range of conditions.

Application of Cationic Emulsion Bitumen K1-70

Emulsion Bitumen K1-70 cationic bitumen emulsion can be used at the ambient temperature at the spray rate of 0.25 to 0.70 litre per square meter (0.05 to 0.15 gallon per square yard)
