The correct answer is: Ring and Ball.
The Ring and Ball test is a standard laboratory test used to determine the softening point of bitumen, which is a crucial property in determining its suitability for various applications, such as road construction and waterproofing.
In this test, a ring-shaped sample of bitumen is placed in a water bath and heated until it softens and deforms. The temperature at which the bitumen softens and touches a metal ball placed on top of it is recorded as the softening point.
The other options are not directly related to determining the softening point of bitumen:
- Impact test is used to determine the impact resistance of materials.
- Flame test is used to determine the fire resistance of materials.
- Viscosity test is used to determine the flow characteristics of fluids, but it's not directly related to the softening point.
So, the correct answer is Ring and Ball.
