This collection contains papers from the International Contest on LTPP [Long-Term Performance Program] Data Analysis 1998-1999. This competition involved university students in the analysis of data in the LTPP database.

Topics include:

• effect of locked-in curvature on portland cement concrete 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 asphalt concrete pavements based on LTPP distress data.
