  • 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.
