1. Soil Classification for Pavement Engineering

Understanding soil classification is pivotal in pavement engineering, affecting the performance and stability of road infrastructure. Various systems, such as the AASHTO and Unified Soil Classification System (USCS), are employed to assess soil suitability based on grain size, plasticity, and load-bearing capacity. The chapter highlights the importance of soil properties, identification methods, challenges in classification, and stabilization requirements.
