About Long-Term Pavement Performance

The Long-Term Pavement Performance (LTPP) program was established to collect pavement performance data as one of the major research areas of the Strategic Highway Research Program (SHRP). The first five years of the LTPP program were completed under the funding and direction of SHRP. Since 1991, the Federal Highway Administration (FHWA) has continued the management and funding of the program. The LTPP program is managed by the Long-Term Pavement Performance Team (HRDI-30) under the Office of Infrastructure Research and Development.

The LTPP program is a large research project that includes two fundamental classes of studies and several smaller studies to investigate specific pavement related details that are critical to pavement performance. The fundamental classes of study are the General Pavement Study (GPS) and the Specific Pavement Studies (SPS).  The combined GPS and SPS programs consist of over 2,500 test sections located on in-service highways throughout North America. The LTPP program will monitor and collect pavement performance data on all active sites. The collected data include information on seven modules: Inventory, Maintenance, Monitoring (Deflection, Distress, and Profile), Rehabilitation, Materials Testing, Traffic, and Climatic.

The LTPP Information Management System (IMS) is the central database where all the data collected under the LTPP program are stored. The LTPP IMS was established in 1988. This database is continuously being developed as more data are collected and processed. Four regional offices are established under the LTPP program to coordinate and communicate LTPP-related activities throughout the United States and Canada.

Features

• Participate in the 2016–2017 T&DI;/ASCE-LTPP International Data Analysis Contest
  
  

  The International Data Analysis Contest is a joint effort of the Federal Highway Administration’s Long-Term Pavement Performance (LTPP) program 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, and thereby contribute to a better understanding of pavement performance.

  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. This year’s contest also includes a challenge topic: 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. Submissions are due by June 1, 2017. Winners will be recognized at the 97h Transportation Research Board Annual Meeting in Washington, DC, January 7, 2018.

  We look forward to your participation in this year’s contest. For more information, contact Deborah Walker at 202–493–3068 or deborah.walker@dot.gov.
