Scope of Highway Engineering

scope:

   The road pavements are generally constructed on small embankments,slightly above the general ground level wherever possible ,in order to avoid difficult drainage and maintenance problems.
The term road or railway thus constructed is therefore termed 'highway' and science and technology dealing with Road Engineering is generally called  'Highway Engineering'.

   In the fore going paragraphs,the need the status of road transportation have been discussed.It is therefore logical to discuss the science of highway engineering which answer the questions as how highways are planned and designed and how they constructed and maintained. Answers to each of these questions contribute to the development of the subject.

   In nutshell,it may be said that the highway engineering deals with various phase like development,planning,alignment,highway geometric design and location, highway traffic operation and its control,materials,pavement design,construction and maintenance,economic considerations,finance and administration.


 Many other special aspect which are not included in the general layout are related to problems of development and construction of hill-roadside development including landscaping road architecture and arboriculture.
