Highway Engineering is a prominent aspect of surface transport. Highway engineering deals with planning, design, construction, operation and maintenance of all types of roads. During the course, the students will learn about the highway related tests on Soil, Bitumen and Aggregate. Students will also get familiar with the test on Modified Binder and modern techniques of highway construction along with use of modern highway construction materials. Course shall also contain design of Highway Engineering.
To impart the knowledge in Highway Geometrics, materials, construction methods and design of different type of pavements along with design of base course and sub–base course
On completion of this course, the students will be able to
- Design various geometric elements of highways.
- Understand the various type of materials used in highway construction along with conducting specified test on the materials as per BSI code for their suitability.
- Perform structural design of flexible and rigid pavements.
- Know various highway constructions techniques and its maintenance
