This master thesis deals with the pavement management system as a tool for a management and maintenance of the roads in the Liberec region. The aim is to collect road failures within the network pavement management system level on roads of 2nd and 3rd class. The resulting data will be used for evaluate pavement condition and make plans of pavement maintenance and rehabilitation in variants. Furthermore, the thesis deals with individual variants in the process of data evaluation when evaluating their suitability and accuracy. The theoretical part summarises the information needed to understand the functioning of the road management system, as well as a description of the software used to collect and subsequent work with the data. In the practical part are presented results of the thesis and moreover the questions arising from the goals set are answered.

Usage of data for the pavement management system on roads II. and III. classes to assess the effects of external influences on the road surface
Skořepová, Eliška ; Mališ, Luděk (referee) ; Hýzl, Petr (advisor)
The master thesis is focused on sorting collected primary data, their subsequent analysis and further comparison in the field of road defects. The collection of pavement failures was done by visual inspection with its recording to a computer for the pavement management system. The data later underwent detailed analysis with the aim to find a potential link between the road defect and the location of the damaged section. The study took place on 2nd and 3rd class roads in the Liberec Region, with special focus on those located near forests. The data collection itself took place in the Liberec Region in 2021. The processing and subsequent evaluation of collected data was done thanks to the availability of comparable data sets from 2014 and 2019 to 2021, so the development of road defects of the selected road network in relation to the surrounding afforestation could be assessed. The last part of this master thesis compares results in different classification levels, time periods and levels of afforestation.

Evaluation of asphalt pavements bearing capacity based on Traffic Speed Deflectometer diagnostics
Březina, Ilja ; Gschwendt,, Ivan (referee) ; Čelko,, Ján (referee) ; Hýzl, Petr (advisor)
The submitted dissertation focuses on the use of a Traffic Speed Deflectometer (TSD) for diagnosing bearing capacity of asphalt pavements, verifying a new method of non-destructive deflection measurements, and producing a method for indicative evaluation of asphalt pavement bearing capacities at the network level in the Czech Republic. The theoretical part describes the principle of TSD device measurements, evaluation methods for measured data, and summarizes the existing foreign experience with TSD devices, including the correlation with a Falling Weight Deflectometer (FWD). The practical part contains an analysis of performed measurements, evaluates the findings of studying the correlation between a TSD device and an FWD device during a comparative measurement in the Czech Republic, and presents a calculation method for deflections from primary data measured by the TSD device. Based on the obtained results, a method for indicative evaluation of asphalt pavements bearing capacities at the network level is designed.
