Course

Unit 1

Introduction – Types and component parts of pavements, factors affecting design and performance of pavements, functions and significance of different layers of a pavement. Test conducted to assess the properties of subgrade soil, aggregate and bitumen. Design of bituminous mixes by Marshall method.

Unit 2

Stress analyses and methods of flexible pavement design – stresses and deflections in homogeneous masses. Burmister’s 2-layer, 3-layer and multi-layer theories. Wheel load stresses – ESWL of multiple wheels, repeated loads and EWL factors – empirical, semi-empirical and theoretical approaches for flexible pavement design. Design of flexible pavements as per IRC. Softwares for pavement design

Unit 3

Stresses analysis and methods of rigid pavement design – types of stresses and causes, factors influencing stresses, general conditions in rigid pavement analysis. Types of stresses – wheel load stresses, warping stresses, friction stresses, combined stresses. Functions of various types of joints in cement concrete pavements – design of longitudinal, contraction and expansion joints as per IRC recommendations. Pavement evaluation and rehabilitation.
