Highways
Objectives
It is intended that the students obtain the necessary knowledge to the planning, conception and design of transportation infrastructures, especially road infrastructures, with focus on geometric design but also considering the basic concepts of earthworks, drainage, paving and safety equipment.

Teaching method
In parallel to the lectures on transportation infrastructures and the expositions on exercises concerning the geometric design, students work in a group to conceive a road section project, which includes geometric design, earthworks, drainage, paving and safety equipment. The evaluation comprises the elements prepared for the group project, the attendance of lectures and practical sessions and a final exam.
Evaluation method
The evaluation includes two components: theoretical-practical (60%); project (40%).
The theoretical-practical component includes 2 written tests during the semester with an equal proportion (50 %).
The project is prepared in a group with a maximum of three students.
Approval requires attendance to at least 2/3 of lectures and 2/3 of practical classes, a project grade higher than 9.5/20, an average grade in tests higher than 9/20 and a minimum final grade of 9,5/20.
Students who attended classes and did the project, in the school year 2018/2019, are dismissed from attending practical classes and doing the road project work.
