Description of Bitumen Emulsion CSS-1h
Bitumen Emulsion CSS-1h is a slow-setting cationic asphalt emulsion that is designed for various paving and industrial uses.
Asphalt emulsions are classified according to the electric charge that surrounds the emulsion’s asphalt particles (i.e. whether it is a cationic or an anionic emulsion) and how quickly the suspended asphalt particles separate from the surrounding water (“breaking”). A slow-setting emulsion is designed to maximize the mixing time with aggregates. Bitumen emulsions CSS-1h is a cationic emulsion. Bitumen emulsions CSS-1h are usually made by passing the mixture of hot bitumen and water phase between a rotating disc, cone, or wheel and a stator. In the emulsification process, the hot binder is mechanically separated into minute globules and dispersed in water treated with a small quantity of the emulsifying agent. The water is called the continuous phase and the globules of the binder are called the discontinuous phase. by proper selection of an emulsifying agent and other manufacturing controls.
Application of Emulsion CSS-1h
While general guidelines can be given for selecting emulsions, laboratory testing is strongly recommended. There is no substitute for a laboratory evaluation of the emulsion and the aggregate to be used. Different types and quantities of emulsion should be tried with the aggregate to find the best combination for the intended use. An experienced technician can determine the type and grade of the emulsion to be used.
- Environmental considerations.
- Proper application for pavement preservation or pavement distresses.
- Traffic type and volume.
Advantages of Bitumen CSS-1h
- Wide variety of emulsion types available today
- Economical
- Free from danger ( for fire )
- Environmental
- Harmless for worker health.
Packing
Packing of bitumen emulsion CSS-1 is in a new thick steel drum on a pallet to prevent any leak inside of container also bulk in bitutainer and tanker.
