Background and Scope of Contest

The International Data Analysis Contest is a joint effort between the Long-Term Pavement Performance (LTPP) program of the Federal Highway Administration (FHWA) and the Task Committee on the Long-Term Pavement Performance Contest, a subcommittee of the Highway Pavement Committee of the Transportation and Development Institute (T&DI) of the American Society of Civil Engineers (ASCE).

Initiated in August 1998, the contest is designed to encourage students, professors, highway agencies, and consultants from around the world to use the LTPP data collected over the past two decades. The contest offers a unique opportunity for contestants (primarily students) to work individually or in a team to perform research that will benefit the highway transportation community. Contestants must document their findings in a written paper. Authors of winning papers will receive a cash prize and an all-expense paid trip to Washington, DC, to be nationally recognized at the 2018 Transportation Research Board (TRB) 97th Annual Meeting. In addition, winners will present their research topic at one or more TRB meeting sessions and will be given the option to have FHWA publish their winning paper, which will be available for researchers worldwide. All participants will receive a letter of recognition from ASCE and FHWA.

 

Background of the LTPP Program

BRIEF HISTORY

During the early 1980s, the 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.

GOAL AND OBJECTIVES

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:

  1. Evaluate existing design methods.

  2. Develop improved design methodologies and strategies for the rehabilitation of existing pavements.

  3. Develop improved design equations for new and reconstructed pavements.

  4. Determine the effects of (a) loading, (b) environment, (c) material properties and variability, (d) construction quality, and (e) maintenance levels on pavement distress and performance.

  5. Determine the effects of specific design features on pavement performance.

  6. Establish a national long-term pavement database to support the program’s objectives and future needs.

 

LTPP EXPERIMENTS AND DATA COLLECTED

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 unique 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 stored in the LTPP database include:

  1. General Test Section Information.

  2. Inventory Data.

  3. Climatic Data.

  4. Materials Test Data.

  5. Maintenance Data.

  6. Rehabilitation Data.

  7. Traffic Data.

  8. Pavement Monitoring Data.

 

The data collected are housed in the LTPP Information Management System. 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.

ACCESSING THE DATA AND OTHER LTPP INFORMATION

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 InfoPaveTM, 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 users 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 (SDR). Each release is sequentially numbered. The most current public release of the LTPP data is SDR 30.0 and is available for download on the LTPP InfoPave Web site at https://infopave.fhwa.dot.gov/ or by contacting the LTPP Customer Support Service Center at ltppinfo@dot.gov or 202–493–3035.

 

Theme, Categories, Awards, Contest Timeline, and Participants

Students are encouraged to focus their analysis and paper topic around the overall contest theme, or may choose to address the challenge topic and enter their paper in that category. The challenge topic focuses on a more specialized component related to ongoing LTPP research with the potential to contribute to other pavement-related research areas.

THEME

The theme for the 2016–2017 T&DI/ASCE-LTPP International Data Analysis Contest is:

Using the Data From LTPP InfoPave™, Analyze/Evaluate Performance Measures Over Time Against
Maintenance and Repair Strategies.
*

*We encourage students to submit papers within the theme. However, any paper using LTPP data will be welcomed.

CHALLENGE TOPIC

This year’s contest includes a challenge topic. The challenge topic for the 2016–2017 T&DI/ASCE-LTPP International Data Analysis Contest is:

Using the LTPP Data (e.g., Distress, Deflection, etc.), Determine Which Data Has the Largest Impact for
Estimating Performance for Better Management of the Highway System.

Many highway agencies still need to gain a better understanding of which pavement data elements have the most impact on highway system performance. The findings from this analysis should provide highway managers with a clear understanding of how different data elements affect pavement performance over time.

A review of the LTPP data should be performed along with a thorough literature review of performance measures and pavement management reports.
