Bärighetsmätning med Traffic Speed Deflectometer

Sammanfattning: The bearing capacity of road E22 from Hurva to Linderöd is analyzed using data from Falling Weight Deflectometer, FWD. A new method called Traffic Speed Deflectometer, TSD, is analyzed and compared to data from FWD to determine the application range of the new method. In addition to these analyzes, various bearing capacity dimensions are explained and used for both methods. From the FWD data a backcalculation is conducted with PMS-object software to determine the stiffness of the layers. The result from TSD showed that for short distances, (300 m), it is not optimal to use the TSD for bearing capacity measurements. It is however for the network level or long distances (30 km), that TSD should be used to its fullest. Then the poor and strong parts can be determined fast and continuously.
