Abstract :

Transportation Infrastructure Plays A Pivotal Role In National Development By Supporting Economic Growth, Trade, And Social Connectivity. Pavement Design, Being The Backbone Of Road Infrastructure, Often Encounters Challenges Such As Escalating Construction Costs, Poor Subgrade Conditions, And The Need For Sustainable Practices. Traditional Empirical Methods Of Pavement Design—though Simple—frequently Result In Excessive Use Of Aggregates And Binders, Leading To Higher Construction Costs And Unsustainable Exploitation Of Natural Resources. This Study Presents A Comprehensive Low-cost Pavement Design Methodology That Integrates IIT PAVE Software, A Mechanistic–empirical Pavement Analysis Tool, With Subgrade Stabilization Techniques Using Lime, Cement, Fly Ash, And Recycled Plastic Waste. IIT PAVE Simulates Pavement Layer Behavior Under Different Loading And Environmental Conditions, Thereby Optimizing Design Thickness And Material Consumption. Subgrade Stabilization Improves Weak Soils’ Load-bearing Capacity, Reduces Pavement Thickness Requirements, And Enhances Durability. The Combination Of Advanced Computational Modeling With Cost-effective Soil Improvement Methods Demonstrates That Pavement Life Can Be Extended By 25–40% While Reducing Initial Construction Costs By Up To 20%. This Study Thus Establishes A Framework For Designing Pavements That Are Not Only Economical And Durable But Also Sustainable And Environmentally Responsible, Providing A Strong Foundation For Future Transportation Infrastructure, Especially In Developing Countries Like India.
