Cutback Bitumen MC-3000

 

Cutback Bitumen MC-3000 Description

Cutback bitumen MC-3000 is dissolved of bitumen in solvents of kerosene. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.

The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long-term softening effect may result.

Our Cutback Bitumen MC-3000 complies with cutback petroleum asphalts of the Medium-Curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004. Cutback Grade Bitumen is normally used in spraying and in some mixing applications. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline, and naphtha, controlling the curing time. Cut back petroleum asphalts of the rapid curing type supplied by ZUMRUT Company are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by ZUMRUT is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. The cutback bitumen (Asphalts) supplied by ZUMRUT are blended from petroleum grade bitumen as stated herein.

Cutback Bitumen MC-3000 Applications

Cutback bitumen MC-3000, characterized by its high viscosity, is typically utilized in specialized applications in road construction and maintenance where increased durability, adhesion, and resistance to environmental factors are required. Here are some common applications:

  1. High-Stress Pavements: MC-3000 is used in the construction of heavy-duty pavements subjected to high traffic loads, such as highways, airports, and industrial areas. Its high viscosity ensures strong adhesion between asphalt layers, reducing the risk of rutting and fatigue cracking.
  2. Base Stabilization: In areas with poor soil conditions or high moisture content, MC-3000 can be applied to stabilize the base layers of the pavement. Its superior adhesion properties help bind aggregate particles together, improving the strength and stability of the base.
  3. Surface Sealing and Waterproofing: MC-3000 is employed in surface sealing applications to protect asphalt surfaces from moisture penetration, oxidation, and wear. Its high viscosity allows for better coverage and sealing of surface defects, prolonging the pavement’s lifespan.
  4. Bridge Decks and Parking Lots: MC-3000 is often used to construct bridge decks and parking lots where durability and resistance to heavy loads are critical. Its strong adhesion and waterproofing properties help prevent moisture-induced damage and extend the service life of the structure.
  5. Cold Weather Applications: In regions with cold climates, MC-3000 can be used for road construction and maintenance during colder months. Its higher viscosity enables it to remain stable at lower temperatures, facilitating application and ensuring proper bonding in cold weather conditions.
  6. High-Traffic Intersections: MC-3000 is preferred for pavement construction at high-traffic intersections and roundabouts, where increased durability and resistance to deformation are essential. Its excellent adhesion properties help maintain pavement integrity under heavy turning and braking forces.
