Question

Structural failures considered in the mechanistic method of bituminous pavement design are

Correct answer (A) Fatigue and Rutting Solution In the mechanistic-empirical design of flexible pavements (e.g., IRC:37), the critical structural failure criteria are: 1. Fatigue cracking of the bituminous layer (due to tensile strain at the bottom of the layer) and 2. Rutting failure in the subgrade (due to vertical compressive strain on top of the subgrade). Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
