Course abstract

The aim of the study course: to master the basic elements of road construction, road construction and the factors influencing it, maintenance and repair, as well as pavement deformations and their impact on traffic safety.
Students learn the types and elements of the road cross-section, as well as the most important road indicators. The study course examines the classification of roads, types and construction of road pavements, road deformations, maintenance and repair works.

Learning outcomes and their assessment

1. Knowledge - is able to show specialized knowledge in road construction, understanding of its constituent elements, paving technologies and factors causing road damage.
2. Skills - the ability to integrate and use the acquired knowledge in the analysis of types of pavements and their damage, as well as to identify the impact of these factors on traffic safety and vehicle operation.
3. Competences - is able to independently analyze different types of pavements and their deformations, influencing factors, and give a qualitative and quantitative analysis based on the obtained data.
• Familiar with road classification, cross-section variants and their elements, and road loads – Test No. 1.
• Capable to use the acquired knowledge creatively when performing road load calculations – Practical works.
• Familiar with the construction of road blankets, deformation, repairs, latest developments in construction – Test No. 2.

• Capable to detect the deformation of road blankets, the reasons for their occurrence and to justify repair options – Practical works.

Criteria for Evaluating Learning Outcomes

The overall assessment of the study course depends on the evaluation of the tests. The final grade of the study course will be calculated as the arithmetic mean of two tests.
Student can get a successful mark for test if at least 50% of the test questions are answered correctly.
Practical works are evaluated according to the established evaluation procedures of such practical works.
