Rapid curing cutback is produced by blending bitumen witha)keroseneb)b...
Introduction:
Rapid curing cutback is a type of bitumen that is produced by blending bitumen with a suitable solvent. It is commonly used in road construction and maintenance activities as a binder for asphalt pavements. The solvent used in the blending process affects the curing time and other properties of the cutback.
Explanation:
The correct answer to the question is option 'C', which is petrol. Here is the explanation:
1. Definition of Rapid Curing Cutback:
- Rapid curing cutback is a type of cutback bitumen that has a relatively fast curing time compared to other types of cutbacks.
- It is produced by blending bitumen with a suitable solvent, which reduces the viscosity of the bitumen and makes it easier to handle and apply.
2. Types of Solvents Used in Cutback Bitumen:
- Different types of solvents can be used in the production of cutback bitumen, including kerosene, benzene, petrol, and diesel.
- The choice of solvent depends on various factors such as the desired curing time, environmental considerations, and availability.
3. Selection of Petrol as the Correct Answer:
- Petrol, or gasoline, is the correct answer in this case because it is commonly used as a solvent in the production of rapid curing cutback bitumen.
- Petrol has the ability to reduce the viscosity of bitumen effectively, allowing for easier mixing and application.
- It also evaporates quickly, which speeds up the curing process and allows for faster setting of the cutback.
4. Other Solvents:
- Kerosene is another commonly used solvent in the production of cutback bitumen, but it is not the correct answer in this case.
- Benzene and diesel are less commonly used solvents for rapid curing cutback bitumen.
Conclusion:
In conclusion, rapid curing cutback bitumen is produced by blending bitumen with a suitable solvent. The correct answer to the question is option 'C', which is petrol. Petrol is commonly used as a solvent in the production of rapid curing cutback bitumen because of its ability to reduce viscosity effectively and evaporate quickly, resulting in faster curing time.

Cutback bitumen:
(i) Cutback bitumen is bitumen with less viscosity which, is achieved by the addition of volatile diluent. Hence, to increase the fluidity of the bitumen binder at low temperature the binder is blended with a volatile solvent.
(ii) The viscosity of the cutback bitumen and the rate at which hardness on the road depends on the characteristics and quantity of both bitumen and volatile oil used as diluent.
(iii) Cutback bitumen is available in three types:
(i) Cutback bitumen is bitumen with less viscosity which, is achieved by the addition of volatile diluent. Hence, to increase the fluidity of the bitumen binder at low temperature the binder is blended with a volatile solvent.
(ii) The viscosity of the cutback bitumen and the rate at which hardness on the road depends on the characteristics and quantity of both bitumen and volatile oil used as diluent.
(iii) Cutback bitumen is available in three types:
- Rapid curing (RC) → In this bitumen is fluxed with Naptha/gasoline, petroleum
- Medium curing (MC) → In this bitumen is fluxed with Kerosene or high diesel oil
- Slow Curing (SC) → In this bitumen is fluxed with High boiling point gas oil
Additional Information
(i) MC and SC cutback are used for priming and viscosity increases as the grade increases like RC-0, RC-1, RC-2.
(ii) RT-1 is lowest viscosity used for surface painting but RT-4 may be used for premix in macadam.
(iii) RT-5 is used for grouting which has highest viscosity.
(iv) MC-2 will be thicker than MC-1 but RC-5 and SC-5 will have same viscosity.
