9.3.9. Solubility Test (IS: 1216)

Try these first

1. 1.

   What is the purpose of the Solubility Test?

   Hint

   Think about why purity might be important.

2. 2.

   Name one solvent used in the Solubility Test.

   Hint

   These are chemicals used to dissolve the bitumen.

3. 3.

   What is the main purpose of the Solubility Test for bitumen?

   • To measure bitumen density
   • To determine the percentage of pure bitumen
   • To assess viscosity

   Hint

   Think about its significance in construction.

4. 4.

   True or False: Solvents like carbon tetrachloride can be used to evaluate the solubility of bitumen.

   • True
   • False

   Hint

   Consider which solvents might be used in the testing process.

5. 5.

   Calculate the solubility percentage if 30 grams of bitumen dissolves in 100 grams of solvent.

   Hint

   Use the formula for calculating percentage based on total mass.

6. 6.

   Discuss potential consequences of using a bitumen sample with a solubility below 60%.

   Hint

   Consider the factors affecting construction quality.
