| Objectives: | The objective of this study is to improve the quality and increase the quantity of monitored traffic data (volumes, classifications, and weights) at the LTPP 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. This multi-year study will attempt to collect research quality data by installing a Bending Plate, Load Cell, or Quartz Sensor at as many of these SPS sites. 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 LTPP's precision requirements for steering and tandem axles, gross vehicle weight, speed, and axle spacing. |
| Comments: | A core objective of the SPS studies is to understand and quantify the relationship between pavement performance, truck volumes, and axle loadings. This pooled fund study is a two-phase project that runs concurrently. Phase I consists of assessing existing Weigh-in-Motion (WIM) equipment that has the potential for meeting LTPP's precision requirements; performing annual field validations on newly installed and existing WIM equipment; and documenting the reliability of the data being collected. Phase II involves determining if a site is suitable for installing a WIM system; installing and maintaining a new WIM system; performing the initial calibration for a newly installed WIM system; downloading and performing validation checks for the previous day's data for the site; and providing a five-year warranty of the system after acceptance of the site by the Federal Highway Administration. The Phase II contractor is only responsible for calibrating and maintaining the systems they install under this project. Any WIM system installed by the highway agency using their in-house staff, must be maintained by the highway agency. This includes calibrating the WIM during the validation activity, if needed. The Phase I contractor will perform the annual field validations for all SPS WIM test sites participating in this study. The Phase I contract was awarded to MACTEC Engineering and Consulting, Inc. in August 2003. The Phase II contract was awarded to International Road Dynamics, Inc. in October 2004. The Phase I and Phase II work activites run concurrently. Although work is underway, States are still welcomed and encouraged to join this project.
