11.11. Preparation of Bituminous Cutbacks

Try these first

1. 1.

   What is the primary purpose of using a solvent in bituminous cutbacks?

   Hint

   Think about how bitumen behaves at room temperature.

2. 2.

   Name one solvent commonly used in preparing bituminous cutbacks.

   Hint

   Which solvent evaporates easily and is used in construction?

3. 3.

   What is a primary function of a volatile solvent in preparing bituminous cutbacks?

   • To increase viscosity
   • To decrease viscosity
   • To solidify bitumen

   Hint

   Think of what happens when you mix oil and water.

4. 4.

   True or False: All bituminous cutbacks require heating to be prepared.

   • True
   • False

   Hint

   Consider the role of heating in dissolving solids.

5. 5.

   If a construction team uses a highly volatile solvent that evaporates too quickly, what issues can arise during application?

   Hint

   Consider what happens to liquids as they get hot.

6. 6.

   Propose a safety checklist for preparing bituminous cutbacks.

   Hint

   Think about the essential safety equipment and protocols.
