Khanna and Justo are two eminent Indian professors and authors who have made significant contributions to the field of highway engineering. They have written several books, papers, reports, and manuals on various aspects of highway engineering. They have also been involved in teaching, research, consultancy, and professional activities related to highway engineering.


One of their most popular books is "Highway Engineering By Khanna And Justo", which is a comprehensive textbook that covers all the topics related to highway engineering. The book is written in a simple and lucid style, with numerous examples, illustrations, tables, charts, diagrams, and photographs. The book is divided into ten chapters, each covering a specific area of highway engineering. The book is suitable for undergraduate students of civil engineering, as well as for practicing engineers, consultants, planners, managers, researchers, and professionals involved in highway engineering.


Chapter 1: Introduction




This chapter introduces the basic concepts and principles of highway engineering. It covers the following topics:


  • Highway development and planning: This topic discusses the history, objectives, scope, and stages of highway development and planning. It also explains the factors affecting highway planning, such as traffic demand, land use, socio-economic conditions, environmental impacts, and legal aspects.



  • Highway alignment and surveys: This topic describes the process of selecting the best route for a highway, considering the topography, geology, hydrology, and other features of the terrain. It also outlines the methods and instruments used for conducting various types of surveys, such as reconnaissance, preliminary, location, and detailed surveys.



  • Highway geometric design: This topic deals with the design of the physical dimensions and shape of the highway, such as width, gradient, curvature, sight distance, super elevation, camber, and transition curves. It also discusses the standards and specifications for highway geometric design, as well as the methods of analysis and optimization.



Chapter 2: Traffic Engineering




This chapter covers the aspects of traffic engineering that are related to highway engineering. It covers the following topics:


  • Traffic characteristics and analysis: This topic explains the basic concepts and parameters of traffic flow, such as volume, speed, density, headway, gap, occupancy, and level of service. It also describes the methods and techniques of collecting, processing, presenting, and analyzing traffic data.



  • Traffic control and management: This topic covers the principles and practices of controlling and managing traffic on highways, such as traffic signs, signals, markings, islands, barriers, lighting, and parking. It also discusses the design and operation of traffic control devices and systems.



  • Road safety and accident prevention: This topic addresses the causes and consequences of road accidents, as well as the measures and strategies for reducing them. It also covers the methods of accident data collection, analysis, investigation, and reporting.



Chapter 3: Highway Materials




This chapter deals with the properties and characteristics of various materials used for highway construction. It covers the following topics:


  • Soil properties and classification: This topic explains the physical, chemical, mechanical, and hydraulic properties of soils that affect their suitability for highway construction. It also describes the methods of soil classification based on grain size distribution, plasticity index, group index, soil classification systems (such as AASHTO and Unified), and soil tests (such as sieve analysis, Atterberg limits, compaction test, CBR test).



  • Bituminous materials and mixtures: This topic covers the types, sources, composition, grading, and properties of bituminous materials (such as asphalt, tar, cutback, emulsion, and modified bitumen) that are used for pavement construction. It also discusses the design, preparation, and testing of bituminous mixtures (such as dense-graded, open-graded, gap-graded, and stone matrix asphalt) that are used for pavement layers.



  • Cement concrete and stabilization methods: This topic covers the types, composition, properties, and tests of cement concrete that are used for pavement construction. It also explains the methods of stabilization of soils and aggregates using cement, lime, fly ash, bitumen, or other additives.
