General description of Cationic Bitumen Emulsion K 1-60
Bitumen Emulsion K 1-60 This product is water-based, ready to use, conforms to the requirements of BS 434: Part 1, and is applied in accordance with BS434:Part 2. Bitumen Emulsion K1-60 is a rapid setting cationic bitumen emulsion is an emulsified asphalt containing minimum 57% bitumen. It is a medium viscosity emulsion used mainly for tack coating in normal overlay and patching work. Bitumen Emulsion K1-60 is chocolate brown in color and is a free-flowing liquid at ambient temperature.

Application of Bitumen Emulsion K 1-6َ0
Emulsion K1-60 adheres exceptionally well, even in damp conditions. The overlay is held securely in place and the entry of water between road pavement courses is hindered. K1-60 may be used as a tack coat in special cases where night construction or high humidity exists. Cationic Bitumen Emulsion K1-60, because of its higher bitumen content, is generally used for surface dressing, patching, retread, and other similar applications.
Asphalt Emulsion K1-60 must only be applied in dry, frost-free conditions which will
remain throughout the film drying period. Temperatures of between 5°C
and 35°C should prevail.
Before application drums should be well rolled to agitate contents before use. Cationic emulsions should be applied by brushing with hand broom or squeegee. Spread in one direction only and avoid scrubbing often. It is more practical to apply by spray as this provides a uniform distribution and even film. Spray equipment should conform to BS3136: Specification for Cold Emulsion Spraying Machines for Roads. Spray evenly to avoid ponding in hollows as this may cause localised “fatting up” of the subsequent courses.
