Long-Term Performance Program: Making Something of It is a collection of papers from the International Contest on LTPP Data Analysis 1998-1999. This competition involved university students in the analysis of data in the LTPP database and was sponsored by the Federal Highway Administration Long-Term Performance Program and the Highway Division Pavements Committee of the American Society of Civil Engineers. The papers include: The Effect of Locked-In Curvature on PCC Pavement; Evaluation of a Pavement Performance Prediction Model Using LTPP Data; Prediction of Pavement Performance - A Neural Network Approach; and Effectiveness of Preventative Maintenance Strategies for AC Pavements Based on LTPP Distress Data.
