Introduction of bitumen emulsion CQS-1h
BACCO Bitumen Emulsion CQS-1h is a cationic asphalt emulsion designed for use in slurry seals and micro-surfacing projects. BACCO asphalt emulsions CQS-1h has a minimum 62% bitumen and it is chocolate brown in color and is a free-flowing liquid at ambient temperature.
The slurry seal process mixes the emulsion, aggregate, and additives in a specially designed machine, which also places the mixture. The cationic emulsion is a chemically stabilized system, so care should be taken not to upset the chemical balance with contamination by chemicals, over-exposure to air, or adverse mechanical or thermal conditions.
Typical properties of CQS-1h
BACCO asphalt emulsion CQS-1h is manufactured strictly as per ASTM D2397-13
AASHTO M208-16.

Applications
BACCO Bitumen Emulsion CQS-1h is recommended to be used for micro surfacing applications and is tailor-made as per design and quality of site aggregates. Also, CQS-1h is used in slurry mixtures for slurry paving projects and ready slurry mix in drum.
Asphalt Emulsion CQS-1h is a Latex Modified Emulsion and can also be used for Crack Seal / Fog Seal applications.
Recommended rate of application
The typical rate of application of BACCO Bitumen Emulsion CQS-1h for micro-surfacing and slurry seal is between 8 -10 % by weight of aggregates.
To ensure the best results
· Use without diluting Bitumen Emulsion with any solvent or water
· Use at ambient temperature
· Roll the Bitumen Emulsion drums 5 times before using
Handling and safety
· Contains petroleum distillate; flammable: keep away from open fire, sparks, or other ignition sources; wear protective clothing, gloves, and goggles.
· Fire flammable when wet, flash point 40°C.
· Skin –avoid repeated or prolonged contact, if this occurs remove with hand cleaner that removes oil or grease, then clean with soap and water.
