What is meant by highway engineering?
Highway engineering is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels to ensure safe and effective transportation of people and goods.
What is highway engineering and its importance?
Highway engineers strive to predict and analyze all possible civil impacts of highway systems. Some considerations are the adverse effects on the environment, such as noise pollution, air pollution, water pollution, and other ecological impacts.
What are the objectives of highway engineering?
(i) Planning a highway network for safe, efficient and fast movement of people and goods. (ii) Keeping the overall cost of construction and maintenance of the roads in the network to a minimum. (iii) Planning for future development and anticipated traffic needs for a specific design period.

What are three major branches of highway engineering?
There are three major branches of highway engineering: planning, research, and construction. Most highway engineers specialize in one of these areas.
What is the purpose of highway development?
The objectives of highway planning are (a) Planning a highway network for safe, efficient and fast movement of people and goods, (b) Keeping the overall cost of construction and maintenance of the roads in the network to a minimum, (c) Planning for future development and anticipated traffic needs for a specific design …
What is NH full form?

What are the functions of highway?
The primary functions of a highway pavement are: Provide a strong and smooth surface to resist traffic loads. 3. Carry traffic loads under repeated application during the anticipated design life without developing excessive or harmful deformations/strains.
What are the layers of highway?
The road pavement structure layers are as follows.
- Subgrade or road bed.
- Sub base course.
- Base Course.
- Surface coarse or wearing course.
Which is the largest NH?
NH 44
NH 44 covers the North-South Corridor of NHDP and it is officially listed as running over 3,745 km (2,327 mi) from Srinagar to Kanyakumari. It is the longest national highway in India.
How many chapters are in the highway engineering handbook?
Overall, this Handbook adopts a comprehensive and integrated approach, and offers a good international coverage. It contains 22 chapters, covering the entire spectrum of highway engineering, from planning feasibility study and environmental impact assessment, to design, construction, maintenance and management.
What are the important elements of Highway geometric design?
Important elements in the geometric design are: cross slope of travel lane, lane width, width and slope of shoulder, and curb (if it is used). 6.4.11.1 Type of Pavement Surface For the purpose of cross section in highway geometric design, AASHTO classifies pavements into high- type and low-type.
What is the best book on human factors for highway engineers?
