Question

The design of flexible pavement is based on ________

(a) slab mechanism

(b) grain to grain transfer

(c) column mechanism

(d) footing mechanism

I have been asked this question in an online quiz.

My query is from Design of Flexible Pavements in division Design of Flexible & Rigid Pavement of Geotechnical Engineering II

Answer 1

The correct answer is (b) grain to grain transfer

For explanation: The design of flexible pavement is based on the principle that the surface load is dissipated by carrying it deep into the ground through the successive layers of granular material. Thus it uses grain to grain transfer mechanism.
