A road fails where the design, the mixture and the roller meet, so this book covers all three.
Asphalt and Subgrade Pavement Design is a complete, practice-oriented guide to modern road materials, construction technology and durability analysis. It begins at the ground beneath the road, showing you how to classify and stabilise a subgrade, interpret California bearing ratio and resilient modulus results, and design drainage that keeps water out of the structure. From there it moves upward through aggregates and unbound layers, performance-graded binders, volumetric mixture design, and the performance tests that reveal rutting, fatigue, moisture damage and thermal cracking before they appear on the road.
Construction chapters follow the material from plant to pavement: production, warm-mix technology, segregation control, joints, rolling patterns and density acceptance. The book then shows how to size a structure by both empirical and mechanistic-empirical methods, compute equivalent axle loads, interpret deflection testing, identify distresses in the field, and design recycling, preservation and overlay treatments. Concrete pavements, traffic loading and load spectra, and pavement management complete the picture, giving engineers and students a single reference that connects soil, mix, construction and structural performance.
What you will learn:
• Classify and stabilise subgrade soils, and interpret CBR and resilient modulus results
• Design drainage and frost protection that keep water out of the pavement structure
• Select performance-graded asphalt binders for a given climate and traffic level
• Run a volumetric mixture design and test for rutting, fatigue, moisture damage and thermal cracking
• Manage plant production, warm-mix technology, segregation, joints, rolling patterns and density acceptance
• Size flexible pavements by empirical and mechanistic-empirical methods
• Compute equivalent axle loads and interpret deflection testing
• Identify pavement distresses in the field and plan recycling, preservation and overlay treatments
• Apply pavement management principles to maintenance and rehabilitation decisions
Written for highway and materials engineers, technicians and civil engineering students, this book is equally suited to practising professionals who need a current reference on pavement design and construction, and to students building a foundation in transportation infrastructure.
