Abstract
A Visual Basic 6.0[TM] computer program for adjusting family performance curves in making reasonable predictions of individual pavement section performance has been developed under this study. The methodology formulated under Texas Department of Transportation (TxDOT) research project no. 0-4186 has been followed to adjust the family performance curves. It is assumed that pavement layer information and date of construction will be known. The appropriate performance curve, along with its basic curve modifiers α, p and β, can be selected from the family of performance curves. When the observed pavement performance does not match the family performance curve, the parameter [x] in the performance equation is varied to adjust the performance curve. This adjustment is considered for each category of pavement distress separately. The computer program has been tested using field data from Long Term Pavement Performance Project (LTPP) and TxDOT Pavement Management Information System (PMIS) data collected on highway sections in Texas.
