Bitumen Emulsion CMS-2 is a medium-setting cationic asphalt emulsion that reacts quickly with the aggregate to convert from an emulsion to asphalt.
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 medium-setting emulsion is one that will break moderately fast when in contact with aggregate. Emulsion asphalt CMS-2 is a cationic emulsion. Emulsion asphalt CMS-2 is usually made by passing the mixture of hot Asphalt and water phase between a rotating disc, cone or wheel and a stator. Based on specifications it may contain other additives, such as stabilizers, coating improvers, anti-strips, or break control agents.
It is well known that water and asphalt will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives. If you are more interested in product information or need to place an order contact or inquire about our Sales team.
Application of Bitumen Emulsion CMS-2
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 Emulsion CMS-2
