Bitumen Emulsion CMS-2h
CMS-2h is a cationic medium setting bitumen emulsion that contains 65% bitumen, is black in color and we manufacture strictly as per ASTM D 2397M-13 standard.
Also Bitumen emulsion CMS-2h consists of three basic ingredients: bitumen, water, and an emulsifying agent. Moreover Based on specifications it may contain other additives, such as stabilizers, coating improves, 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.
Emulsion Emulsion CMS-2 is a cationic emulsion. Emulsion asphalt CMS-2 are usually made by passing the mixture of hot bitumen and water phase between a rotating disc, cone or wheel and a stater. In the emulsification process, the hot binder is mechanically separated into minute globules and dispersed in water treated with a small quantity of emulsifying agent. The water we call the continuous phase and the globules of the binder we call the discontinuous phase.by proper selection of an emulsifying agent and other manufacturing controls.
Application of Bitumen Emulsion CMS-2
We maybe use Cat-ionic Bitumen emulsion CMS-2 at ambient temperatures with aggregates, which need not be completely dry. To clarify Emulsions are less hazardous to use in comparing with the cutback and can be applied in a wider range of conditions. So Most CMS-2h applications we list as below:
- Bituchip (Chip seal)
- Bituseal (Seal coat)
Also Ideally suited and designed for
- Pot hole filling/patch work
- Premix carpet work
- Strong bonding with existing surface
- High stability of patches
Successful performance of emulsion asphalt requires selecting the proper type and grade for the intended use. To clarify Guidelines presented in this chapter should help select the specific grade and type of emulsion to be used.
The first consideration in picking the right type and grade of the emulsion is how the emulsion will be used. Therefore Is it for a planned mix (central or mixed-in-place), a recycled mix, or a prime coat application? Also is it for some type of surface application, such as a fog seal, slurry seal, micro surfacing, or chip seal? Is it for a maintenance mix? Therefore Once we made this decision , we must to consider other project variables. Some other factors that affect the selection are:
• Firstly Climatic conditions anticipated during construction. The choice of emulsion grade, the design of mix or treatment, and the selection of construction equipment should be dictated by the conditions at the time of construction.
• Secondly Aggregate type, gradation, and availability.
• Thirdly Contractor or construction equipment availability.
• Moreover Geographical location. The hauling distance and, in some cases, water availability are important considerations.
• Traffic control.
• Most importantly Environmental considerations.
• Moreover Proper application for pavement preservation or pavement distresses.
• in conclusion Traffic type and volume.
