Conventional Pavement Structure

This study compares different conventional pavement structures including asphaltic concrete paving, graded aggregate base, and cement treated base. The evaluation focuses on stress levels, subgrade preparation, minimum CBR values, apparent density, material costs, and construction details for optimized performance and cost efficiency.
