2022.5.30 A rigid pavement, as the name implies, is a type of pavement that stays like a rigid slab under the loading. The rigid slab bridges the low-bearing or poor compacted soil. So, rigid pavement is an ideal pick if you have poor bearing soil or the loading is heavy. Normally, civil engineers construct rigid pavement with un-reinforced or plain ...
