The applying research institution developed two standards, which regulate the bases, the criteria of use, choice, execution and maintenance of pavements in unbound construction with and without overgrowth, in collaboration with the VSS Expert Commission 6.01 "Maintenance". During these discussions it became obvious, that the whole subject of secondary traffic surfaces (roads, paths and squares) should be treated in a group of standards together with the aspects of design.

These standards concern horizontal and vertical alignment, cross fall, drainage installations as well as the strong relations between construction, maintenance and operation. According to the Commission the subject should be treated in two separate standards for rural roads and car parks. 

The research work contains the execution of the necessary research in situ and in literature, developing the standards "Design of rural roads" and "Design of car parks" in collaboration with the Expert Commission 6.01 as well as writing the research report.
