Comprehension exercises in class, as well as homework, combined with oral examination.	4Χ4=16

Learning Objectives

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

1. be familiar with the main quality control tests on pavement materials
2. deepen on laboratory testing and on field testing
3. analyze and evaluate the results of quality controls
4. Understand the usefulness of testing in terms of quality assurance of pavement construction

Teaching Methods

Teaching methods	Class Lectures and Laboratory lectures. Discussion of case studies in class. PC calculations with Excel and computational codes.
Teaching media	Power Point presentations and Videos.
Laboratories	Yes/ Data collection for exercises, student participation.
Computer and software use	Students solve simple exercises using mainly EXCEL in PC.
Assignments (projects, reports)	Students compete in thematic exercises that are solved in the classroom, corrected by the instructors and returned. They are also examined orally in thematic exercises that are solved at home.

Student Assessment

• Assignments (projects, reports): 80%
• Oral exam: 20%
