We supply premium Cutback Bitumen formulated by blending high-purity penetration-grade bitumen with controlled petroleum solvents. Cutback bitumen remains fluid at lower temperatures, making it easier to handle and apply without extreme heating on site.

Once sprayed or mixed, the volatile diluent evaporates into the atmosphere, leaving behind a durable, high-adhesion bitumen binder layer.

Product Grade Classifications

We supply three distinct cutback categories depending on your required setting speed and application depth:

Medium Curing (MC-30, MC-70, MC-250)

  • Solvent Type: Kerosene-based diluent.

  • Key Characteristics: Slower evaporation allows deep penetration into unbound base materials before curing.

  • Primary Uses: Prime coats over aggregate bases, dust suppression, and stockpiled asphalt patching.

Slow Curing (SC-70, SC-250)

  • Solvent Type: Low-volatility heavy oil or diesel cutter.

  • Key Characteristics: Retains fluidity over extended periods, providing long-lasting flexibility.

  • Primary Uses: Soil stabilization, road oiling, and long-term cold mix asphalt stockpiles.

Key Applications in Road Construction

  • Prime Coating (MC-30 / MC-70): Sprayed directly over crushed stone, gravel, or soil-cement base courses. It penetrates capillary pores, binds loose aggregate, seals against water infiltration, and creates an adhesive bond for subsequent asphalt layers.

  • Tack Coating (RC-70 / RC-250): Sprayed as a thin coating between existing pavement (concrete or asphalt) and new asphalt overlays to prevent slipping or layer separation.

  • Chip Sealing & Surface Treatment (RC-250 / MC-250): Applied hot followed immediately by crushed aggregate chips to form an economical, water-resistant wearing surface for rural roads and highway shoulders.

Our packaging & delivery options include;

  • 200-Liter Steel Drums: Brand-new, heavy-duty steel drums (~180 kg net weight) ideal for medium-sized job sites, remote projects, or long-term storage.

  • Bulk Bitumen Tankers: Insulated distributor trucks equipped with heating coils and calibrated spray bars for direct site spraying.
