Course abstract
The course gives general information about roads and squares, their construction, exploitation and impact on the environment. The course includes theoretical background for design of roads and squares. The course also includes types of road structures and equipment.
Learning outcomes and their assessment
• Knowledge: about roads and squares, specific requirements for design; materials used for construction of roads and squares; road structures – attendance of lectures, tests.
• Skills: to perform designing of roads in accordance with the existing design codes; to make a good choice for environmentally friendly building materials and engineering structures - course project (BūvZ3129 – Roads and Squares II).
• Competence: ability to analyze projects of roads and squares, their potential negative impact on the environment – test, conversation about course project (BūvZ3129 – Roads and Squares II).
Course Content(Calendar)
Full time intramural studies:

4. Road planning. Design criteria. Elements of design: horizontal alignment. Sight distance, horizontal and transition curves. (1 h)
5. Superelevations. Widening of carriageway on curves. (1 h)
6. Longitudinal profile of road. Elements of longitudinal profile. (1 h)
7. Road junctions; at-grade and multi level road junction schemes. (1 h)
1. test – three questions from the first part of the course plan (1.-7.). (1 h)
8. Subgrade construction. Soil classification and characterization. Subgrade deformation types. Slope protection. (1 h)
9. Surface drainage; environmental impacts. Roadside ditches. Groundwater control. (1 h)
10. Road pavements. (1 h)
11. Road structures. Culverts and bridges. (1 h)
12. Road equipment. Content and layout of road project. (1 h)
13. Squares – requirements for squares and pavement structure. (1 h)
14. Roads and environmental protection. Road construction. Impact of road construction works on the environment. Road maintenance and repair. (1 h)
2. test – three questions from the second part of the course plan (8.-14.). (1 h)
Part time extramural studies:
All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar.
Requirements for awarding credit points
Successfully written two tests - formal test with a grade.
Description of the organization and tasks of students’ independent work
Two tests. In each test three questions from the study course program.
Criteria for Evaluating Learning Outcomes
Formal test grade is calculated as the arithmetic mean of the two tests grades. In each test, the student must demonstrate knowledge of the study course program.
