Description of Cationic Bitumen Emulsion K 1-40

Bitumen Emulsion K 1-40 are cold applied, liquid bitumen emulsions, used in the construction and repair of pavements, driveways, roads, and highways. In accordance with these standards, This product is denoted by the prefix ‘K’ signifying a cationic emulsion. This product is water-based, ready to use, conforms to the requirements of BS 434: Part 1, and are applied in accordance with BS434:Part 2. Therefore K1-40 denotes rapid break, cationic emulsion with 40% normal bitumen content.

In accordance with these standards, this product is denoted by the prefix ‘K’ signifying a cationic emulsion. Cationic Bitumen Emulsion K1-40 is a rapid setting cationic bitumen emulsion is an emulsified asphalt containing minimum of 40% bitumen and 60% water. It is a low viscosity emulsion used mainly for tack coating.

Application of Bitumen Emulsion K 1-40

Bitumen Emulsion K1-40 is a cold applied rapid-acting 40% cationic bitumen emulsion. When cured K1-40 forms a thin but uniform film of bitumen on the road surface which gives an adhesive bond between a bituminous overlay and an existing surface. For best results, tack coating is strongly recommended when performing such tasks as overlaying with hot rolled asphalt, macadam or when patching or carrying out inlaid work.

All surfaces must be dry and free from dust, oil, grease, fuel spillage, mud, leaves, etc. In hot weather, it may be advisable to dampen the surface with water in order to retard the loss of water from the emulsion as it cures and to ensure better wetting of the surface by the emulsion. It is essential that the surface is free of standing water prior to and during application.

Asphalt Emulsion K1-40 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.
