Introduction to Bitumen Cutback MC 3000
Cutback Bitumen MC3000 plays a pivotal role in various road construction applications. It serves as the essential tack coat in grit seals, sand seals, Otta seals, and single seats, primarily for lightly trafficked roads. This high-viscosity cutback bitumen boasts a significant binder content, ensuring optimal wetting of cover aggregates while creating a bitumen film that enhances adhesion to the base layer.
Utilizing Bitumen MC3000: Best Practices
Calibrated Application: Apply using a calibrated distributor at a binder spray temperature of 135°C, with a minimum road surface temperature of 15°C and rising.
Safety Considerations: Exercise caution during heating as Bitumen MC 3000 contains flammable cutters with a flash point exceeding 40°C.
Curing Time: Curing duration varies based on prevailing weather conditions.
Distinguishing MC3000 from MC 30
While both MC 30 and MC 3000 serve crucial roles, they differ significantly in composition and viscosity. MC 30 comprises 58% penetration grade 80/100 mixed with 42% kerosene, whereas MC 3000 consists of 85% penetration grade 80/100 combined with 15% kerosene. This variance results in MC 30 having the lowest viscosity among medium curing grades, while MC 3000 boasts the highest viscosity.
Applications of Cutback Asphalt MC 3000
It including Bitumen MC 3000, are instrumental in reducing bitumen viscosity for primer applications on road pavements. The incorporation of kerosene as a cutback agent, at varying concentrations per local conditions, makes MC 3000 ideal for prime coat and cold applications due to its ease of use without the need for thinning or extensive heating. MC 3000 facilitates waterproofing, capillary void filling, and bonding loose mineral particles.
Packaging and Quality Assurance
Typically is packaged in sturdy steel drums on pallets to prevent leaks. Additionally, bulk options in bitutainers and tankers offer versatility in transportation. Quality assurance is paramount, with ATDM guaranteeing compliance with ASTM/EN 15322:2009 standards through rigorous inspection and batch testing.
