CMS

Specification of Bitumen CMS

Bitumen CMS is typically produced by passing a hot bitumen and water mixture through a rotating disc, cone, or wheel with a stator. In this emulsification process, the hot binder separates into tiny globules, dispersing in water treated with a small quantity of emulsifying agent. The water serves as the continuous phase, while the binder globules form the discontinuous phase. Through proper selection of emulsifying agents and manufacturing controls, various types and grades of emulsified asphalts are created.

Advantages of Using Bitumen CMS

• No petroleum solvent required for liquefaction.
• Minimal or no hydrocarbon emissions.
• Usable without additional heating in most cases.
• Capability to coat damp aggregates effectively.
• Applicability with cold materials in remote areas.
• Wide range of emulsion types available.

Applications of Bitumen CMS

The chemical and physical properties of Grade CMS directly influence its applications:

• Sealing: CRS-1, CRS-2, M-80, V Prime, Pre-coating emulsions.
• Slurry Surfacing: CQS, CQS-1h, LMCQS, Microsystems.
• Patching/Crack Filling: CSS, CSS-R, CMS, CMS-R, SS-1.
• Fog Seal: SS-1, CSS, CSS-R, CMS, CMS-R.
• Cold Mix: CMS, CMS-R, specialty emulsions.
• Tack Coating: CRS-1, CSS, SS-1, specialty emulsions.
• Dust Control: CSS, SS-1, specialty emulsions.
• Stabilization/Recycling: CSS, CMS, specialty emulsions.
• Waterproofing/Roofing/Home Applications: Specialty emulsions.
• Agriculture: SS-1, CMS, specialty emulsions.

Packing of CMS

Bitumen CMS is packed in new, thick steel drums placed on pallets to prevent leakage inside containers. It is also available in bulk within bitutainers and tankers.
