This document describes the development of updated rigid pavement distress prediction models for the Texas Department of Transportation's Pavement Management Information System (PMIS). It makes use of pavement condition data in databases maintained by the Texas Department of Transportation (TxDOT) and the Center for Transportation Research (CTR) at the University of Texas at Austin. Models are presented to quantitatively predict the following distress types: In jointed concrete pavement - patches, corner breaks, faulted joints and cracks, spalled joints and cracks, transverse crack spacing, and slabs with longitudinal cracks; and, In continuously reinforced concrete pavement - punchouts, patches, serviceability loss as measured by ride score, transverse crack spacing, and crack spalling. Modifying factors to the general model equation include the influence of structural effects, climate, and traffic loading on the various distress types. These models greatly improve the preliminary estimates, which were made in 1993 and are currently used in the PMIS. These improvements to the models were made possible primarily by data collection efforts undertaken in the summer of 1994. This document discusses the analysis of the data collected, which includes a condition survey conducted by the CTR and a survey of Texas districts to determine coarse aggregate use in construction of rigid pavement in the state.
