Study of Long-Term Pavement Performance (LTPP): Pavement Deflections

Preface

BACKGROUND

In 1998, the Federal Highway Administration (FHWA), the Long-Term Pavement Performance (LTPP) program, and the Transportation and Development Institute (T&DI) of the American Society of Civil Engineers (ASCE) initiated a program to organize an international contest on the use of LTPP pavement performance data. The competition was designed to promote the use of LTPP data and involve students, academicians, and pavement engineers in the analysis of data from the LTPP database. The program has been in operation for 5 years with 4 contests. The papers in this document are the winners of the 2003–2004 contest.

DATA ANALYSIS CONTEST

The contest has been expanded to cover four categories:

Category 1—Undergraduate students (individual or team entry).
Category 2—Graduate students (individual or team entry).
Category 3—Partnership.
Category 4—Curriculum.

The contest involves participants from universities, State highway agencies, and industry. T&DI continues to provide oversight of the contest with strong support from FHWA.

Experts from academia, industry, and highway agencies reviewed the 20 papers submitted for the 2003–2004 contest and gave awards for the best paper in each category. The following are the winners:
