23.2.3. Bituminous primers

Try these first

1. 1.

   What is a bituminous primer made of?

   Hint

   Think about the components mentioned in the section.

2. 2.

   Why is porosity important for bituminous primers?

   Hint

   Consider how absorption affects the binding process.

3. 3.

   What primary materials make up a bituminous primer?

   • A mixture of sand and cement
   • Penetration bitumen and petroleum distillate
   • Tar and concrete

   Hint

   One component is a type of liquid asphalt.

4. 4.

   True or False: Higher porosity in road surfaces enhances the effectiveness of bituminous primers.

   • True
   • False

   Hint

   Think about how a sponge absorbs water.

5. 5.

   Evaluate the effects of using a bituminous primer on a non-porous surface like concrete. What would be the result?

   Hint

   Consider how non-porous surfaces interact with liquids.

6. 6.

   Design a specification guide for selecting a bituminous primer based on surface types. What factors would you consider?

   Hint

   Think about what surfaces may require special considerations.
