Course detail

Road Building Machines

FSI-NSK Acad. year: 2019/2020 Summer semester

The course is to acquaint students with the technology of road construction and machinery used in their construction as a machine for plating, compaction mechanisms, machines for construction of concrete and asphalt roads and their construction design.

Language of instruction

Czech

Number of ECTS credits

5

Learning outcomes of the course unit

Students will be able to choose the concept of meeting the technological and technical equipment requirements, specify the main components and machine projection addressed. It is able to propose optimal technological assembly machinery to build roads on the basis of their technical parameters and options.

Prerequisites

Students are required to have basic knowledge of physics, machine parts and their mechanism, physics of materials and the course Earth Working Machinery.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Part of the course can be excursions to the companies, which manufacture or operate the equipments from the thematic area of education.

Assesment methods and criteria linked to learning outcomes

Classification and assessment of the student credit: Excellent (90-100 points), very good (80-89 points), good (70-79 points), satisfactory (60-69 points), sufficient (50-59 points), failed (0-49 points).

Aims

The aim and task of the course is to acquaint students with the design layout and main technical parameters of compaction machinery, construction machinery for asphalt and concrete roads, machinery for the repair of roads and automation of machinery for road construction. Acquainted with the principles of design and planning in respect of technology and technical requirements.

Specification of controlled education, way of implementation and compensation for absences

Course-unit credit is awarded on condition of having attended the exercises actively and worked out assigned projects. Presence in the exercises is obligatory.
