• Abstract:
  The purpose of this TechBrief is to discuss one of the Long Term Pavement Performance (LTPP) program's stringent data requirements - site-specific measurements for estimating pavement loadings - and to illustrate the effects of traffic loading data error on LTPP's ability to develop accurate and reliable design equations. This TechBrief is based on two studies: "Vehicle Volume Distributions by Classification" and "Results of an Empirical Analysis of Alternative Data Collection Sampling Plans for Estimating Annual Vehicle Loads at LTPP Test Sites", both by M. Hallenbeck and published in July 1997. 4 p.
