The 'rigid pavement' (concrete) in India uses which slab design method per IRC:58?
Choose the correct answer
Only CBR-based thickness table (same as flexible)
Mechanistic-empirical edge stress analysis (Westergaard + fatigue) using k, fcr, and design ESALs per IRC:58-2015
Only Marshall test results
Simply dividing total load by allowable bearing capacity
Correct Answer
B. Mechanistic-empirical edge stress analysis (Westergaard + fatigue) using k, fcr, and design ESALs per IRC:58-2015
Why is this the answer?
IRC:58-2015: mechanistic-empirical design for rigid (JPCP = Jointed Plain Concrete Pavement). Design inputs: (1) Design traffic (ESALs); (2) Foundation modulus k (effective modulus of subgrade reaction); (3) Concrete flexural strength (fcr). Critical stresses: edge warping + edge load stress (day-time) and corner load + curl stress (night-time) checked against fatigue model. Joint spacing: 4–5 m for JPCP, 15–50 m for CRCP.
