Bitumen CMS2 the Power of Medium-Setting Emulsions

bitumen cms2

General Description of  Bitumen  CMS2

Bitumen CMS2 stands out as a top-tier cationic medium-setting emulsion, boasting a minimum 65% bitumen content and adherence to the stringent ASTM D 2397M-13 standard. This emulsion, tinted in a sleek black hue, promises optimal performance across various construction scenarios.

The Power of Medium-Setting Emulsions CMS2

Medium-setting emulsions like CMS-2 are engineered for efficiency, swiftly reacting with aggregates to transition from emulsion to asphalt. The classification based on electric charge ensures precise performance, while the moderate breaking speed upon contact with aggregates ensures reliability in diverse environmental conditions.

Applications of Bitumen CMS2

Premixing Excellence: CMS-2 shines in premixing applications, offering a chocolate-brown, free-flowing liquid that facilitates seamless blending with aggregates.

Chip Sealing Brilliance: Ideal for chip sealing with dirtier aggregates, CMS-2’s medium-setting nature necessitates adaptable traffic control measures, ensuring optimal outcomes.

Patch Repair and Pothole Solutions: From blow-off to proper filling techniques, CMS-2 excels in patch and pothole repairs, delivering durable, heavy asphalt films.

Premix Carpet Efficiency: Leveraging CMS-2 for premix carpet applications ensures economical and swift construction of wearing courses, adding to its multifaceted utility.
