Maintenance and Data Services for Long-Term Pavement Performance (LTPP) Weigh-in-Motion (WIM) Systems

Project Information

Project ID: 
FHWA-PROJ-04-0002
Project Abstract: 

This multiyear study will attempt to collect research-quality data by installing a Bending Plate, Load Cell, or Quartz Sensor at as many of these 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.

Goal

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.
