Description of Bitumen Emulsion K1-60
Bitumen Emulsion K1-60 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 K1-6َ0
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.

FAQs
1. In what ways is K 1-60 distinct from other emulsions like RS, MS, or SS types?
K 1-60 is a cationic bitumen emulsion of high viscosity and average set time. It is good for coating and adhesion and is most suitable to applications that require good bonding and intermediate workability. It’s a middle way between fast-setting and slow-setting emulsions.
2. Does K 1-60 require heating before use?
No, K 1-60 is a cold-applied emulsion not requiring heating and enhancing safety and reducing environmental impact by removing hot bitumen fumes.
3. For how long will the K 1-60 emulsion have a shelf life?
K 1-60 has a normal shelf life of 4 to 6 months depending upon storage in sealed containers in a location sheltered from direct sunlight and extremes of temperature. Before application, it must be stirred to offer an even consistency.
4. Is K 1-60 acceptable to apply in rainy or humid environments?
Yes, since it is cationically formulated, K 1-60 works well in damp and humid environments. Still, avoid application in heavy rain so that it cures and adheres well.
5. May I apply K 1-60 for surface dressing or tack coat?
K 1-60 is suitable for light surface dressing and tack coat application, with high adhesion and resistance. Heavy surface dressing work could be better accomplished with polymer-modified or rapid-setting emulsions.
