Conventional Pavement Structure
This document examines the construction and performance characteristics of conventional and inverted pavement structures, emphasizing the specifications for 12.25-inch and 2-inch asphaltic concrete paving over graded aggregate bases with cement-treated bases. It highlights critical metrics, including stress levels, minimum CBR values, and cost comparisons for different structural designs. The study concludes with a cost analysis, providing total placement costs per square yard and outlining optimal conditions for durable asphaltic pavement applications.
