KN-55
CATIONIC UNSTABLE BITUMEN EMULSION
SHORT DESCRIPTION
Cationic unstable bitumen emulsion KN-55 is single-component homogenous liquid of brown color in which the minute droplets of bitumen are dispersed in water.
FEATURES
Emulsion complies with the standard SRPS EN 13808. The emulsion breaks when in contact with stone aggregate or asphalt surface. Bitumen gets bound to aggregate or to the surface, and the water evaporates.
USAGE
It is used for surface spraying and as the binding layer between other layers in construction of pavement coating. Its application ensures the such connection of layers that the whole pavement behaves as one homogenous plate. Emulsion is being applied from the distributing device or sprayers. The spraying should be performed at least 2-3 hours before the asphalt coating. It is favorable to heat up the emulsion to 40-60ºC. When spraying the unbound granulated surface the application rate is 0.5 to 1.5 kg/m2, and for bound granulated surface it is 0.5 to 1.0 kg/m². For spraying between asphalt layers the application rate is 0.4-0.5 kg/m2. The emulsion must be stirred before application.
