Civil Engineering > GATE 2026 SET-2 > Pavement Design
Consider the following statements with respect to rigid pavements:
Statement-1: Bottom-up cracking (BUC) in rigid pavements is caused at the edge of the slab due to combined effect of single or tandem rear axle load and positive temperature differential.
Statement-2: Top-down fatigue cracking (TDC) in rigid pavements is caused due to repeated cycles of axle loads and negative temperature differential.
The CORRECT option is:
