Comparison of Ride Improvement for Various Roadway Rehabilitation Methods in Western Canada (Poster)
The objective of this project is to determine if significant differences in the magnitude of the roughness reduction in each waveband exists between treatments and between agencies. While IRI is an accepted measure of roughness, a more in-depth method was developed to determine the nature of the roughness for each project which was affecting the ride characteristics (and in turn IRI). All pre-construction profile data collection in AB and BC and all post construction data collection in AB was collected by the same high speed inertial profiling platform as part of network PMS data collection programs. The post construction data collection in AB was typically collected the year after construction. Post construction data collection was carried out by BC MoTI Field Services immediately following construction. The post-rehabilitation Short Wavelength energy levels are substantially lower for the BC projects when compared to the Alberta projects. This has been attributed to the BC post-rehabilitation profile measurements being conducted immediately following construction. In contrast, Alberta projects were tested the following year. Different rehabilitation treatments result in different levels of roughness reduction in each waveband of interest. Although rehabilitation treatments applied in Alberta result in differing levels of roughness reduction, in all cases, Alberta treatments result in a more uniform reduction across all wavebands. In contrast, the same rehabilitation treatments applied in BC result in less reduction in the Long and Very Long wavebands.
