| Roadmap/Focus area(s): | Infrastructure Research and Technology Strategic Plan and Roadmap | |
| Project Description: | This multiyear study will attempt to collect research quality data by installing a Bending Plate, Load Cell, or Quartz Sensor at as many of the Specific Pavement Study (SPS) sites as economically possible. For the purpose of this study, research quality data is defined to be at least 210 days of data (in a year) of known calibration meeting the Long-Term Pavement Performance (LTPP) precision requirements for steering and tandem axles, gross vehicle weight, speed, and axle spacing. | |
| Goals: |
A core objective of the Long-Term Pavement Performance (LTPP) Specific Pavement Study (SPS) is to understand and quantify the relationship between pavement performance, truck volumes, and axle loadings. The objective of this pooled fund study is to improve the quality and increase the quantity of monitored traffic data (volumes, classifications, and weights) at the SPS-1, -2, -5, -6, and -8 test sites. There are a total of 64 SPS-1, -2, -5, and -6 test sites and 20 SPS-8 sites throughout North America.

| Test Methodology: | This pooled fund study has two phases that run concurrently. This contract represents phase I, and it consists of performing annual field calibrations and validations of Weigh-in-Motion (WIM) systems according to the Long-Term Pavement Performance (LTPP) field procedures. Information on the phase II activities for this study can be found under "Installation, Maintenance and Data Services for Long-Term Pavement Performance Weigh-in-Motion Systems." | |
| Partners: | Federal Highway Administration: Office of Policy and Governmental Affairs - Office of Highway Policy Information; Role(s): Technical, Advisory | |
| Expected Benefits: | The expected benefit is quality traffic data. | |
| Deliverables: | 1. Name: Field Calibration and Validation Report (for each site visit). Product Type(s): Research report Description: The contractor is required to submit a written report of the field activities for the Long-Term Pavement Performance (LTPP) Specific Pavement Study (SPS) Weigh-in-Motion (WIM) systems. 2. Name: Weigh-in-Motion System Field Calibration and Validation Annual Report Product Type(s): Research report Description: The contractor provides a summary of all the field visits performed in the contract year. | |
