Course detail

Pavement Diagnostics and Management (DST)

FAST-CM051Acad. year: 2018/2019

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.
