The International Data Analysis Contest is a joint effort between the Long-Term Pavement Performance (LTPP) program of the Federal Highway Administration and the Task Committee on the LTPP Contest, a subcommittee of the Highway Pavement Committee of the Transportation & Development Institute (T&DI) of the American Society of Civil Engineers (ASCE). The contest is designed to encourage university students, professors, and highway agency engineers from around the world to get involved in using the LTPP database.The theme for the 2015 T&DI/ASCE-LTPP International Data Analysis Contest is: Use of LTPP Data for Managing Pavement Assets. This year’s contest includes a challenge theme. The challenge theme for the 2015 T&DI/ASCE-LTPP International Data Analysis Contest is: Develop Pavement Health or Condition Indices Using the LTPP Data. Submissions are due by July 17, 2015. Winners will be recognized at the 95th Transportation Research Board Annual Meeting in Washington, D.C., in January 2016.We look forward to your participation in this year’s contest.

During the early 1980s, the Transportation Research Board (TRB) of the National Research Council, under the sponsorship of FHWA and with the cooperation of the American Association of State Highway and Transportation Officials (AASHTO), undertook a thorough study of the deterioration of the Nation’s highway and bridge infrastructure system. The study recommended that a “Strategic Highway Research Program (SHRP)” be initiated to focus research and development activities that would make major contributions to improving highway transportation. The report, published as “TRB Special Report 202” in 1984, emphasized six research areas, with the Long-Term Pavement Performance (LTPP) program as one of the key research areas. During 1985 and 1986, independent contractors developed details of the research programs for SHRP. The detailed programs were published in May 1986 as a TRB Report entitled “Strategic Highway Research Program—Research Plans.”
The LTPP program was transferred from SHRP to FHWA in 1992 to continue the work. The program provides research studies of inservice pavements as envisioned by SHRP: as a comprehensive program to satisfy a total range of pavement information needs. It draws on technical knowledge of pavements presently available and seeks to develop better models to explain how and why pavements perform as they do. The LTPP program also seeks to gain knowledge of the specific effects on pavement performance due to various design variables, such as traffic, environment, materials, construction quality, and maintenance practices. As sufficient data become available with time, analysis is conducted to provide better performance prediction models for use in design and pavement management.
The goal of the LTPP program is to increase pavement life by investigating various designs and rehabilitated pavement structures, using different materials and under different loads, environments, subgrade soil, and maintenance practices. The specific objectives of the LTPP program are to:
The LTPP program includes two experiment categories: General Pavement Study (GPS) experiments and Specific Pavement Study (SPS) experiments. Within each experiment category, several types of studies have been evaluated by the LTPP program. The GPS experiments consist of inservice pavement test sections throughout the United States and Canada. They embrace an array of site selection factors that provide information for a national database to meet the objectives of the LTPP program. The SPS experiments have their own set of limited goals, construction needs, and experimental approaches that cannot be achieved by the GPS experiments. The SPS experiments are intensive studies with specific evaluation variables.
Several broad classes of data are stored in the LTPP database, including:
The data collected are housed in the LTPP Information Management System (IMS). It is the world’s largest pavement performance database ever created, with enormous potential for the development of products to improve pavement technologies in the future.
The LTPP database evolves continuously to accommodate data collected over 25 years. The data are stored using a relational database design that involves over 6,000 data elements in over 400 tables. This approach greatly enhances the system’s ability to store massive amounts of data in a very organized method. However, the LTPP storage scheme makes data accessibility somewhat difficult because it requires extensive knowledge of the information and format of the LTPP database, which includes information on the database structure, data codes, data collection, testing protocols, and relationships between data tables. To address the need for a structured and user-friendly LTPP data source, the data have been made available in a variety of formats throughout the years. The latest and most enhanced system is LTPP InfoPave™, a Web-based system that provides easy access to the LTPP data as well as access to LTPP software tools, research reports, and other program information. LTPP InfoPave is an excellent tool that allows students to explore the LTPP database, become familiar with the data types, and examine the availability of suitable LTPP test sections to use for analysis. Students are required to use LTPP InfoPave to compete in this contest.
The LTPP program updates the database throughout the year and provides an annual release of the database to the public at the TRB Annual Meeting in Washington, DC. The public release is known as the LTPP Standard Data Release, or SDR. Each release is sequentially numbered. The most current public release of the LTPP data is SDR 28.0 and is available by contacting the LTPP Customer Support Service Center at firstname.lastname@example.org or 202–493–3035 or by downloading it from the LTPP InfoPave Web site.
Students are to focus their analysis and paper topic around the overall contest or challenge theme. The challenge theme will focus on components of ongoing LTPP research that has the potential to contribute to other pavement-related areas.
The theme for the 2015 T&DI/ASCE-LTPP International Data Analysis Contest is:
Use of LTPP Data for Managing Pavement Assets.

Graduate and undergraduate students who graduate anytime during the academic year are eligible to participate. Students who are full-time employees on LTPP-related contracts are NOT eligible to participate in the contest. Students who wish to participate in the contest must be sponsored by at least one faculty advisor. Student participants must submit a letter of sponsorship from the faculty advisor showing the advisor’s support and that the paper was neither published nor previously submitted for publication elsewhere. However, after submission for the contest, students may choose to submit their papers for publication elsewhere, either before or after the contest review process is complete.
Faculty advisors are NOT permitted to be coauthors with students in the undergraduate or graduate categories, but their names can be listed as “Faculty Advisors” on the submitted paper manuscript. The award prize goes to the students on the team. Faculty members, however, can participate as contributing authors (after the lead student authors and any partners) in the Partnership category.
Nonstudents or faculty may participate with students under the Partnership category. Other participants may include researchers, pavement designers, materials engineers, traffic forecasters, and other professional disciplines from highway and other agencies, and international organizations such as the International Road Federation, World Road Association-PIARC, and the World Bank. The student(s) must be the lead author(s) on the paper, the award prize is given only to the students(s).
The paper preparation guidelines are provided in Appendix A. Each paper must have a cover page including authors’ names, affiliations, and addresses. The cover page must also list the category under which the paper is being submitted. An example of the cover page format is shown in Appendix B.
