Question

In the lower layers of the flexible pavement, lower quality materials are used.

(a) True

(b) False

I have been asked this question in class test.

I'd like to ask this question from Design of Flexible Pavements in section Design of Flexible & Rigid Pavement of Geotechnical Engineering II

Answer 1

Correct answer is (a) True

The explanation: The flexible pavement distributes the load by grain-to-grain mechanism that involves many layers. As the load is distributed, it decreases in magnitude with the depth. Therefore, in the lower layers of the flexible pavement, lower quality materials are used.
