Road surface texture: definitions and measurements (micro and macrotexture). International Roughness Index: definition and measurement. Acoustic outlines. Traffic noise prediction and reduction. Road pavement noise components. Low noise pavement materials. Open graded asphalt mixes. Lightweight aggregate asphalt mixes. Distress definitions for flexible pavements. Cracking. Distorsion. Disintegration. Skid hazard. Road marking materials: evaluation and monitoring. Pavement Condition Index PCI. Road applications of bituminous emulsions. Pavement reinforcement systems. Flexible Pavement Maintenance and Rehabilitation.

Development of the examination
LEARNING EVALUATION METHODS
Oral exam

LEARNING EVALUATION CRITERIA
The learning evaluation criteria consists of two examinations: - evaluation of the knowledge necessary for the preparation the practice exercise; - oral examination focused on course topics. The practice exercise can be carried out as a group work; each group consists of, at most, five students. A positive score in the first test (practice exercise) is mandatory in order to access to the oral examination. In the case of a negative score in the oral examination, the student has to repeat again both tests. In order to pass positively the examinations, the student needs to prove to have fully understood the course topics and to have learned the criteria of the visual identification of the pavement distress and their measuring criteria.

LEARNING MEASUREMENT CRITERIA
Assignment of a final score (maximum score is 30)

FINAL MARK ALLOCATION CRITERIA
In order to pass the examination with a minimum score, the student needs to know sufficiently each course topic. Higher score will be assigned based on the general and specific competences. The maximum score will be achieved by proving an extensive knowledge of the course topics during the examinations. The score ”cum laude” will be assigned to the student that will obtain the maximum score and will be able to prove a strong competence on the subject as well as to excel in the oral examination.
