Railway part:
The reasons, needs, circumstances, methods and standards of the various tests are explained in a classroom. The tests are presented and performed as laboratory exercises.
Road part:
The role of the main parameters of asphalt mixtures and their raw materials and the test principles of each characteristic, as well as European standard test methods will be explained in a classroom. The individual tests are presented in the laboratory and specific tests are performed under the supervision of the students.

A félév közbeni munkaszüneti napok miatt a program csak tájékoztató jellegű, a pontos időpontokat a tárgy honlapján elérhető "Részletes féléves ütemterv" tartalmazza.
Textbooks:
- A. T. Papagionnakis, E. A. Masad: Pavement Design and Materials
- Asphalt Institute: Superpave Mix Design
- Asphalt Institute: Mix Design Methods
Online materials:
- Presentations
- Electronic lecture notes
Participation in laboratory exercises is 100% compulsory. A student who is absent from one or more exercises cannot obtain credit for the course. In case of an absence, the department provides one opportunity to complement for the absence during the week of repeats.
Due to the nature of the tasks, there is no need for a consultation outside of the timetable.
II. Tárgykövetelmények
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via 2 tests (1 test of railway part and 1 test of road part) and active participation.
| Evaluation form | Abbreviation | Assessed learning outcomes |
