Principles and main parts of machines, mechanisms and plants. Technological processes, main mechanisms and their usage in earth works, improved subgrade, base course of unbound materials, stabilised and hydraulically bound materials, asphalt courses and Portland cement pavements. Technology of mixing, transportation, construction, compaction and quality control are presented. Furthermore pavement maintenance, repair and recycling technology and mechanisms are presented. Main mistakes in road constructions are documented. In exercises each student individually prepares the system of mechanisms for specified earth works, bitumen courses and different details of road and street construction and reconstruction.
