Cationic CMS-2h Asphalt Emulsion Overview
Asphalt emulsion consists of three basic ingredients: asphalt, water, and emulsifier. Based on the specifications, this product may contain other additives, such as stabilizers, coatings, anti-strips, or damage control agents. It is known that water and bitumen will not mix, except under carefully controlled conditions using special equipment and chemical additives.
CMS-2h asphalt emulsion is a Cationic emulsion. CMS-2h asphalt emulsion is typically made by passing a mixture of hot asphalt and aqueous phases between a rotating disk, cone or wheel and the stator. In the emulsification process, the hot binder is mechanically separated into small granules and dispersed in water treated with a small amount of emulsifier. The water is called the continuous phase and the binding clots are called the discontinuous phase. With the proper selection of emulsifying agents and other manufacturing controls.
CMS-2h emulsion asphalt application
Cationic emulsion can be used at room temperature with aggregate, which does not have to be completely dry. Emulsion is less hazardous to use than reduction and can be applied under a wider range of conditions. Most of the CMS-2 applications are listed below:
- Bituchip (Chip seal)
- Bituseal (Seal coat)
Also, Perfectly suited and designed for:
- Pot hole filling / patch work
- Premix carpet work
- Strong bond with existing surface
- High patch stability
Successful asphalt emulsion performance requires selecting the correct type and grade for the intended use. The guidelines presented in this chapter will help you choose the class and emulsion type to use.
The first consideration in choosing the right emulsion type and grade is how the emulsion will be used. Is it for a planned mix (central or onsite mix), recycled mix, or prime coat application? Is it for some type of surface application, such as fog seal, slurry seal, micro-surface, or chip seal? Is this for a mix of treatments? Once this decision is made, other project variables must be considered. Some of the other factors that influence the selection are:
- Climatic conditions are anticipated during construction. The choice of emulsion class, mix design or treatment, and selection of construction equipment must be determined by conditions at the time of construction.
- Aggregate type, grading and availability.
- Availability of construction contractors or equipment.
- Geographical location. Transport distances and, in some cases, water availability are important considerations.
- Traffic control. Is traffic reversible or controlled only through the work area?
- Environmental considerations.
- Appropriate application for preservation of asphalt roads or asphalt road difficulties.
- Traffic type and volume.
Although general guidelines can be given for selecting emulsions, laboratory testing is highly recommended. There is no substitute for laboratory evaluation of the emulsion and aggregate to be used. Different types and amounts 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 level of emulsion to use.
Cationic emulsions are preferred for use with negatively charged silica aggregates such as quartz, granite, sandstone and river gravel. In general, Cationic emulsions can be used with a wider range of aggregates, will tolerate a greater amount of moisture, and will break apart at lower ambient temperatures. The main application areas of Emulsion asphalt are surface coating, tack layer, prime coat, slur seal and cold blending.

Advantages of using CMS-2h emulsion asphalt
- No petroleum solvent required to dilute
- Little or no hydrocarbon emissions
- In most cases, it is used without additional heat. No need to preheat. Resulting in handling cases for the user, in addition to saving costs.
- Ability to coat wet aggregate. It can be used even with wet aggregates allowing the user to do work also during the rainy season.
- Can use cold materials in remote locations. Bitumen Emulsion cold application ensures safety for the workforce; this is a user friendly product. Being cool applied, jobs progress faster.
- Various emulsion types are available today
- Economical
- Free from harm (for fire)
- Environmentally Friendly
- Not harmful to workers' health.
- Can be used with moisture aggregates. It can be used even with wet aggregates allowing the user to do work also during the rainy season.
- Low application temperature and does not need heating during storage and transportation period. For this reason, it provides energy savings.
- The emulator increases adhesion due to its effect as an anti-stripping agent
- Can be used in four seasons. Primarily it provides application opportunities in rainy areas and extends the application period.
- Has many application areas and construction methods.
- Bitumen emulsion does not require petroleum solvent to make it liquid like cutting and also does not need to be heated like ordinary Bitumen. So that it saves imported petroleum or firewood.
- Toxic fumes (Hydrocarbon emissions) are usually emitted from heated asphalt & amp; cutting is absent when the Cationic Bitumen Emulsion is used, as no heating is required for the application.
CMS-2h asphalt emulsion packing
Packing the CMS-2h asphalt emulsion is in a new thick steel drum on the pallet to prevent leakage in the container as well as bulk in bitutainers and tankers.
