Pavement condition survey
The pavement condition survey (PCS) conducted by our team assessed the overall condition of City of Yelm, WA, maintained roadway segments for the project. The project totaled 42 centerline miles of road.
To carry out the survey, our staff rode each street segment and followed a nationally recognized distress identification manual. This manual helped determine the severity and extent of seven distresses. These distresses were used to determine the PCI of each segment and the entire roadway network.
After completion of the survey, our experts provided a report that described methodologies, procedures, and recommendations. Our team explained these details at an online deliverables meeting.
Pavement lifecycle model development
Using the data collected in the PCS, we created a working pavement lifecycle model that supported the City’s infrastructure investment planning processes. The model included multiple budget scenarios and predefined treatment options.
Furthermore, treatment options featured preservation-prevent (rejuvenators), crack seal, patching, preservation-correct (micro-surfacing, slurry seal etc.), rehabilitation, and Full Depth Reclamation (FDR).
Managed services
After WithersRavenel delivered the model, our team provided Yelm with managed services for the length of the PCS contract, then annually. These services allow for updating the model as infrastructure is added or repaired throughout the year. We also provide support for any questions regarding the existing model or budget simulations and results.
