• Description:
  Accurate knowledge of traffic volumes and loading is essential to structural pavement design and performance.
  
  Underestimation of design traffic can result in premature pavement failures and excessive rehabilitation costs.
  
  Overestimation can result in overly conservative pavement designs that are not cost effective for the owner agency.
  
  Traffic input for the anticipated National Cooperative Highway Research Program (NCHRP) 1-37A Design Guide
  
  will be in terms of axle load spectra along with several other important traffic parameters. Axle load spectra consists
  
  of classifying traffic loading in terms of the number of load applications of various axles configurations (single, dual,
  
  and tridem) within a given weight classification range.
  
  Long term pavement performance (LTPP) data from Mississippi sites were extensively reviewed to determine vehicle
  
  class distribution, monthly and hourly distribution factors, and axle load spectra. This data will serve as baseline data
  
  for Mississippi Department of Transportation (MDOT) implementation of the new mechanistic-empirical structural
  
  pavement design guide.
