This module covers theories of flexible pavement design, including the critical concepts of structural number (SN) and layered systems. Engineers will learn pavement thickness calculation methods and explore practical examples that demonstrate real-world applications of design principles.

This module teaches engineers how to plan and execute comprehensive geotechnical investigations that provide the essential soil data required for successful pavement design. Understanding subsurface conditions is critical for preventing premature pavement failures and optimizing material selection and thickness design.

This module emphasizes the critical importance of proper drainage in pavement performance. As shown in the chart, moisture-related issues account for nearly half of all pavement failures. Engineers will learn comprehensive drainage design principles, surface and subsurface drainage solutions, and methods to evaluate the impact of moisture on pavement structure and longevity.

The chart compares different subgrade improvement methods based on cost-effectiveness and implementation difficulty. Properly prepared subgrade is essential for pavement performance, as it serves as the foundation for the entire structure. This module teaches engineers how to evaluate existing soil conditions and select appropriate improvement techniques based on soil properties, project requirements, and local constraints.

This module covers established methodologies for determining appropriate pavement layer thicknesses, including the AASHTO method, mechanistic-empirical design, Shell method, Asphalt Institute method, and IRC guidelines. Engineers will learn to apply these approaches to diverse projects while considering local conditions, material properties, and performance requirements.

This module explores mathematical models used to predict pavement deterioration over time, as illustrated in the chart comparing flexible and rigid pavement performance. Engineers will learn to apply probabilistic methods, regression models, and mechanistic approaches to forecast how pavements will perform under various traffic and environmental conditions, enabling more informed maintenance and rehabilitation decisions.

This module teaches engineers how to perform comprehensive economic analyses of pavement alternatives using Life Cycle Cost Analysis (LCCA) principles. As shown in the chart comparing flexible and rigid pavements, the analysis considers initial construction costs, future maintenance expenses, rehabilitation requirements, user costs, and residual values to determine the most cost-effective solution over the entire design life.

This module examines how temperature fluctuations impact pavement materials and structural performance. Engineers will learn to select appropriate binder grades and mix designs for specific climate zones, implement thermal management strategies, and design pavements resistant to temperature-related distresses. Understanding these effects is critical for ensuring pavement longevity in diverse environmental conditions.

This module explores cutting-edge approaches to sustainable pavement engineering, including material conservation through recycling and reclamation, energy efficiency improvements in production and construction, emissions reduction strategies, and design optimizations that extend service life while minimizing resource consumption. Engineers will learn practical methods to balance environmental, economic, and social considerations throughout the pavement life cycle.
