19.5. Types of Flexible Pavements

Try these first

1. 1.

   What is a conventional layered flexible pavement?

   Hint

   Think about the order of materials in terms of cost and quality.

2. 2.

   Name one advantage of full-depth asphalt pavements.

   Hint

   Consider traffic load and material accessibility.

3. 3.

   What type of pavement uses high-quality materials on top?

   • Contained Rock Asphalt Mat
   • Full-Depth Asphalt Pavement
   • Conventional Layered Flexible Pavement

   Hint

   Think of the layering principle since it’s all about quality.

4. 4.

   True or False: Full-depth pavements are directly built on the sub-grade.

   • True
   • False

   Hint

   Recall how they differ from layered systems.

5. 5.

   Considering the traffic in an urban area, discuss the pros and cons of using conventional layered vs. full-depth asphalt pavements.

   Hint

   Use traffic loads and material costs to guide your analysis.

6. 6.

   Design a conceptual schematic for a CRAM with appropriate dimensions and materials for a low-traffic rural road.

   Hint

   Think about what materials would suit low-traffic, keeping it simple and effective.
