MEDIUM CURING CUTBACK BITUMEN (MC-250)

  General information:

 

 

  • Priming and Tack Coating – Cutback bitumen’s suitable for priming are also used for tack coats, which are applied to an underlying surface to help with the adhesion of subsequent asphalt layer.
  • Primer Sealing – Where temperatures are too cool for an effective priming operation, or where traffic is likely to upset a primed surface before the final seal can be sprayed, a primer seal can be used to give adequate protection of the pavement for periods of up to 6 to 12 months. Cutback bitumen’s suitable for primer sealing can also be used in the manufacture of pre-mix asphalt, which is used in repairs.
  • Sprayed Sealing – Cutback bitumen’s are used extensively in sprayed sealing applications, particularly in cooler weather where they provide improved initial stone retention due to their lower viscosity.
  • Packing : 220, 230 , 240(Liter) new steel drum
