• Abstract:
  The existing formulas used by the Texas Department of Transportation (TxDOT) to allocate the statewide
  
  maintenance budget rely heavily on inventory and pavement evaluation data. These formulas include
  
  regional factors and rainfall indices that vary by district to account for differences in environmental and soil
  
  factors across the state. The existing regional factors were developed in the 1990s and were intended to
  
  reflect differences in environmental and soil factors between districts. It is not known how these factors
  
  were calculated since no documentation is available that explains their development. Since the regional
  
  factors were introduced, the Texas Transportation Institute has completed a project in which a database of
  
  climatic and soil factors were compiled to characterize the variation of climatic and soil conditions across
  
  Texas. TxDOT’s Maintenance Division realized the potential value of using this information and directed an
  
  implementation project to re-examine the existing regional and rainfall factors with the objective of revising
  
  the current factors to better reflect differences in climatic and soil conditions between districts. This report
  
  documents the evaluation of the existing rainfall and regional factors and the development of a revised set of
  
  factors for maintenance cost allocation.
