What is MC 30 cutback bitumen?
MC-30 is a type of medium curing cutback bitumen which is suitable for cold regions. It applies in road maintaining operations including tack coats and slurry seals. This type of liquid bitumen is constituted of a penetration grade bitumen and a petroleum based solvent.
What is MC in asphalt?
Medium-curing (MC) cutback asphalt cement is a combination of medium diluents of intermediate volatility, typically in the kerosene boiling point range, and asphalt cement.
What are the types of cutback bitumen?
There are different types of cutback bitumen like rapid curing (RC), medium curing (MC), and slow curing (SC). RC is recommended for surface dressing and patchwork. MC is recommended for premix with less quantity of fine aggregates. SC is used for premix with appreciable quantity of fine aggregates.
What is the difference between cutback and emulsion?
8– Due to bitumen emulsion has ionic structure, it sticks to the aggregates or surface, but, cutback bitumen is neutral and just acts as a coat.
What is the meaning of 60 70 bitumen?
The penetration of Bitumen is used to measure its grade. It is reported as a penetration value of mm/10. Bitumen penetration grade 60/70 means the penetration value is in the range 60 to 70 at standard test conditions which commonly used as a Paving Grade.
What is MC-70 asphalt?
MC-70 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluents or cutter of medium volatility. The diluents temporarily reduce the viscosity of the asphalt cement for ease of handling and application.
What is RC MC and SC?
Asphalt cutbacks use petroleum solvents for dissolving asphalt cement. On the basis of the relative speed of evaporation, cutback asphalts are divided into three types: rapid curing (RC), medium curing (MC) and slow curing (SC).
What is VG 30 bitumen?
What is vg 30 bitumen? This bitumen is primarily used for the construction of extra-heavy bitumen pavements that have to bear significant traffic loads. Bitumen VG30 is the most widely used type of bitumen in road construction, insulation, building construction industries, and also in the production of cutback bitumen.
What is the grade of cutback?
Three grades are available: 50 sec, 100 sec, and 200 sec. The majority of cutback bitumen is used in the surface dressing but a significant amount is also used for the Manufacture of both standard and deferred set asphalts.
What is the difference between bitumen and cutback bitumen?
How is cutback bitumen produced?
Cutback bitumen is a petroleum product produced by diluting bitumen in petroleum hydrocarbon (Kerosene). The aim is to decrease the viscosity and to increase the penetration of bitumen on asphalt surface. In comparison with bitumen, cutback bitumen is sprayed on different layers of roads in a notably lower temperature.
