Course Details
Pavement Diagnostics and Management (DST)
Academic Year 2024/25
NMB009 course is part of 1 study plan
NPC-SIK Summer Semester 1st year
The function of roads, road user requirements and their transition to structural reliability requirements and characteristics of serviceability. External and internal sources of failure mechanisms, defining various failure mechanisms, their development and characteristics. Diagnostics of various failures of asphalt, cement concrete and block pavements with a design of maintenance and repair. Systems for the management of road networks.
In the seminars, students learn the field and laboratory methods used to determine the characteristics of serviceability, measurement and evaluation of the bearing capacity with the design of maintenance and repairs. The individual work of failure evaluation by visual inspection, design of pavement structure, evaluation of the measurement of the bearing capacity using falling weight deflectometer and design of maintenance and repair will be elaborated.

Entry Knowledge
Knowledge of subjects: Highways I, II, Urban roads and knowledge of Road laboratory tests
Aims
The knowledge of requirements, function and failure of road and street, diagnostics and design of maintenance, rehabilitation and recycling of road structures are the main goal.
The student is able to manage the goal of the subject by getting a complex overview over the quality system in road construction, particular technologies and necessary machinery, which are used for the construction, maintenance, rehabilitation and recycling of the road structures.
