CATIONIC UNSTABLE POLYMER BITUMEN EMULSION
Cationic unstable polymer bitumen emulsion PmB KN-65 is single-component homogenious liquid of brown color, in which the minute droplets of bitumen and polymer are dispersed in water.
Emulsion satisfies requirements of the standard SRPS EN 13808. The emulsion breaks when in contact with stone aggregate or asphalt surface. Bitumen with polymer gets bound to aggregate or to the surface, and the water evaporates.
It is most often used as a binder in two-layer surface treatment. The previously prepared surface is being sprayed with the emulsion preheated to 50-60 ºC, in the amount of about 2 kg/m2. Then, the mineral aggregate is applied, exclusively of eruptive origin and of granulation of 8-11 mm, in the amount of 20 kg/m2, and it is being rolled into the surface with the pneumatic roller. Emulsion is then sprayed again in the amount of about 10 kg/m2, and another layer of aggregate is applied, of granulation 4-8 mm, in the amount of 1 kg/m2. Rolling with the pneumatic roller is started immediately and continued until the binder becomes solid. Emulsion should be stirred before application.
