Project Objective

Conduct applied research to evaluate long-term pavement performance.

Project Abstract

In 1987, Congress funded the Strategic Highway Research Program (SHRP). As part of SHRP, several pavement test sections were selected for monitoring around the country. Construction as well as performance data have been collected on all test sections and saved in the Long Term Pavement Performance Information Management System LTPP IMS. The collected data is very beneficial for researchers as well as practitioners in investigating the long-term performance of pavements. Recently, the Federal Highway Administration released a computer program called Data Pave to help in making LTPP data available for any interested party. It is the main objective of this study to evaluate the capabilities of Data Pave and evaluate some of the pavement performance data for Region 8.

Task Descriptions

FY 1999-2000

The following tasks will be performed in the first year of the project:

• Task 1 – Obtain copies of the latest version of Data Pave.
• Task 2 – Identify the capabilities of Data Pave.
• Task 3 – Prepare a national survey with emphasis on Region 8 to determine useful applications for Data Pave. The survey will provide detailed information on the most important data analysis for DOTs in Region 8.
• Task 4 – Deliver an interim MPC report summarizing the capabilities of Data Pave and all results from the survey.
• Task 5 – Develop a detailed plan for the tasks to be performed in the second year of the project.

In the second year of the project, a database containing performance data for pavement sections in Region 8 will be extracted from Data Pave. Comprehensive data analysis will be performed on the database. In addition, a final MPC report will be prepared. The results from this research project will also be submitted for publication to the Transportation Research Board.

Relationship to Other Research Projects

The national survey performed will ensure that this project will not duplicate any other research efforts in Region 8.

Technology Transfer Activities

Transportation Departments in Region 8.

Potential Benefits of the Project

This research will be very useful in determining the effectiveness of various materials and pavement construction techniques in Region 8. It will help pavement practitioners to make cost effective decisions.
