Pavements

Course Description:

Students will focus on issues related to the design of flexible, semi-rigid, semi-flexible and rigid road and airfield pavements. Basic differences between road and airfield pavements. Methodologies for the design of road and airfield pavements, mechanical characteristics of materials, mix design in the laboratory and quality control.

Prerequisite Knowledge

Basic knowledge covered by the courses “STRENGTH OF MATERIALS”, “SOIL MECHANICS” and “ROAD CONSTRUCTION”.

Learning Objectives

Upon successful completion of the course, students will be able to:

  1. evaluate types of mixtures in the laboratory
  2. implement methodologies for the analysis and design of all types of pavements
  3. make use of the possibilities of analyzing and designing airfield pavements
  4. be aware of the quality control requirements at the individual stages of construction of a pavement and during the final delivery.
  5. comprehend the content and importance of the Tender Documents for a pavement construction project.
