Course Objectives:

• Being able to recognize and use current common pavement design procedures.
• Understanding common design and construction features important to the performance of both asphalt and concrete pavements.
• The ability to design and recognize specification and construction activities that can improve the performance of pavements.
• Evaluating the condition of pavements through surface condition surveys, smoothness, friction, load/deflection and other evaluation techniques.
• Understanding the basic components of pavement management systems and how they can be used to optimize funding expenditures.
• Communicating and promoting good road design and construction practices.

Course Outcomes:

• Select appropriate earth moving and compaction equipment depending upon the Requirement
• Prepare quality assurance and quality control plans in an attempt to construct Better Performing pavements
• Evaluate the pavements based on the functional and structural characteristics
• Understand constructions of non bituminous & bituminous & cement concrete Pavements for flexible & rigid pavements.
