RS 2

Understanding RS 2

RS-2 is a rapid-setting, anionic water-based emulsified asphalt supplied in bulk.

Key Properties:

  • Boiling Point: 212°F
  • Specific Gravity: 1.01 (H₂O=1)
  • Percent Volatile: 0%
  • Solubility in Water: Soluble
  • Appearance: Brown liquid with a faint petroleum odor
  • Flammability: Non-flammable

Recommended Use:
RS-2 is designed as a bituminous binder for chip seals. It is crucial to apply it using well-calibrated distributors to ensure proper application.

Application Guidelines

  • Distributor Setup: Ensure distributor nozzles and spray bars are appropriately sized and calibrated for the desired shot rate.
  • Shot Rate Determination: Establish the shot rate through a laboratory chip seal design tailored to the project’s aggregate and existing pavement conditions.
  • Temperature Requirements:
    • Ensure air and pavement temperatures are sufficiently high for the emulsion to cure effectively.
    • Ideal conditions for application are when air temperatures are above 50°F and rising.

Usage Tips

  • Conduct thorough testing and calibration to achieve optimal performance.
  • Monitor weather conditions to guarantee suitable application temperatures for effective curing.
