Pavement analysis and design is a branch of civil engineering focused on determining the structural composition of roadways, airports, and industrial yards. The primary goal is to create a structure that can withstand predicted traffic loads and environmental conditions over a specified design period without experiencing structural failure or excessive deterioration. pavement analysis and design
Rigid pavements (typically Portland Cement Concrete) rely on the high flexural strength of the concrete slab to carry the load. The slab acts as a beam, bridging minor weak spots in the subgrade. | | Outputs | |------------|--------------| | AASHTO 1993
