Rationale:

Construction of roads is one of the major areas in which diploma holders in Civil Engineering may get very good opportunities for employment. The diploma holders are responsible for construction and maintenance of highways and airports. Basic concepts of road geo-metrics, surveys and plans, elements of traffic engineering, road materials, construction of rigid and flexible pavements, special features of hill roads, road drainage system and various aspects of maintenance find place in above course.

Learning Outcomes:

After undergoing the subject, students will be able to:

• classify the roads as per IRC types and geometrics
• explain various components of a flexible/rigid pavement
• select various highway materials and test them for different quality parameters
• supervise construction of a highway in plain areas and hilly areas
• supervise repair and maintenance of roads
• supervise preparation of bituminous mix in the hot mix plants
• describe the use various road construction equipment
• describe basic terminology of various components of an airport.

Instructional Strategy:

While imparting instructions, it is recommended that emphasis should be laid on constructional details and quality control aspects. Students should be asked to prepare sketches and drawings, clearly indicating specifications and constructional details for various sub components of a highway. It will be also advantageous to organize field visits to show the actual construction of roads at site.

Means of Assessment:

1. Assignments and quiz/class tests
2. Mid-term and end-term written tests
3. Actual Practical Performance
4. Report Writing
5. Viva-voce
