PmB KN-60
CATIONIC UNSTABLE POLYMER BITUMEN EMULSION
SHORT DESCRIPTION
Cationic unstable polymer bitumen emulsion PmB KN-60 is single-component homogenous liquid of brown color, in which the minute droplets of bitumen and polymer are dispersed in water.
FEATURES
Emulsion satisfies requirements of the standard SRPS EN 13808. The emulsion breaks when in contact with asphalt surface. Bitumen with polymer gets bound to the surface, and the water evaporates.
USAGE
It is used as the binding layer between asphalt layers in construction of highways and roads with heavy traffic load, when polymer bitumen is used as binder in asphalt production. 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. For spraying between asphalt layers the application rate is 0.4-0.5 kg/m2. The emulsion must be stirred before application.
