SCOPE OF HIGHWAY ENGINEERING

The road pavements are generally constructed on small embankments, slightly above the general ground level wherever possible, in order to avoid the difficult drainage and maintenance problems. 

The term road or roadway thus constructed is therefore termed 'highway' and the science and technology dealing with Road Engineering is generally called 'Highway Engineering'.

Highway engineering deals with various phases like,

Development

Planning

Alignment

Highway Geometric design and location

Traffic Control

Highway Materials

Pavement design (Flexible & rigid Pavement)

Construction and maintenance

Economic considerations

Financial and administration, etc.

Development, Planning and Locations
Aspects :- 
Historical background; Basis for Planning: Master Plan, Engineering surveys and highway alignment.

Highway Design, Geometrics and Structures Aspects :-
Road Geometrics and their Design; Rigid and Flexible Pavements; Design factors and thickness design; Overlay design; Design of drainage system.

Traffic Performance and its Control 
Aspects :-
Traffic studies analysis; Need for new road links; Traffic regulation and control; Intersection design and their controls with signs, signals, islands and markings. 

Materials, Construction and Maintenance Aspects :-
Highway Materials and mix design; Highway construction: Earth work, construction of different types of pavements; Earthen, soil stabilized, water bound macadam, Bituminous surfaces and cement concrete roads; pavement failures; pavement evaluation, Maintenance of pavements and drainage system.

Economics, Finance and Administration Aspects :-
Road user cost and economic analysis of highway projects, pavement types and maintenance measures; Highway Finance and phasing of expenditures; Administration.

It also deals with other special aspects like,

Problems of hill road construction

Road side development

Landscaping

Legal issues, etc.
