CATIONIC SEMI-STABLE BITUMEN EMULSION
Cationic semi-stable bitumen emulsion KP-55 is single-component homogenous liquid of brown color, in which the minute droplets of bitumen are dispersed in water.
Emulsion satisfies the requirements of 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.
It is used for surface spraying and as the binding layer between asphalt layers in construction of pavement coating. Its application ensures 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.
