What is specific gravity?
Think about the relationship between mass and volume.
How can specific gravity impact the choice of bitumen in pavement construction?
Consider the implications of weight and density.
What does specific gravity indicate in bitumen?
Relate this to the concept of density.
True or False: Specific gravity for bitumen typically ranges from 0.95 to 1.05.
Recall the typical values discussed.
A sample of bitumen has a mass of 980 grams with a volume of 1 liter. Calculate the specific gravity of the bitumen and discuss what this implies for its use in construction.
Consider how this density impacts construction suitability.
If you have two bitumen samples with specific gravities of 0.95 and 1.01, explain how you would choose which to use for a high-load road. What factors would you consider?
Think about the properties required for high-load applications.
