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.
