Prevention of environmental vibrations from uneven roads and sleeping policemen
conference paper
KOAC•WMD Dutch Road Research Laboratories and TNO Building and Construction Research have developed the perfect tool to predict the level of vibrations generated by traffic passing sleeping policemen and/or uneven roads. The tool consists of a quick investigation of the wave propagation through soil and subgade and a dedicated software code for processing the data. A modified Falling Weight Deflectiometer (FWD), 3-D geophones and a data logger are used for in situ investigation. The testing takes 10 minutes per location. The computer software encompasses:
• Various vehicle types
• Different shapes and altitudes of speed ramps and/or a measured longitudinal road profile
• Transfer functions for vibrations through soil into buildings
• A dynamic finite element calculation module
The results of the calculations can be compared to disturbance and damage guidelines.
