The Indiana Department of Transportation (INDOT) is increasingly committed to the Pavement Management System. For this reason, updated simple pavement performance prediction models with the least number of explanatory (independent) variables are required to predict the performance of various pavement types for future planning of rehabilitation or replacement. In Indiana, the two main pavement types are jointed concrete pavement (JCP) and bituminous pavement (BIT). 1999 and 2000 year data were used to develop regression models for different pavement types for the Interstate and Non- Interstate Roads systems. The International Roughness Index (IRI), in inches per mile, was mainly used for …
