The course provides a comprehensive overview of pavement layers and materials, covering both flexible and rigid pavement designs. It begins with the fundamental components and functions of road pavement layers, emphasizing the classification and properties of subgrade soil and stone aggregates, including the California Bearing Ratio (CBR) test. The course then delves into bituminous materials, exploring their classification, properties, and various tests such as specific gravity, penetration, and viscosity. It also covers the design and testing of bituminous paving mixes, including the Marshall Mix Design and associated tests for evaluating mix performance. Additionally, the course addresses the properties of Portland cement and the mix design for cement concrete. In the design segments, students learn about the factors influencing the design of flexible and rigid pavements, with practical application through case studies and the use of design methods such as IRC guidelines and IIT Pave software. The course culminates in a detailed study of joint design in rigid pavements and comprehensive design problem-solving exercises.
