DRISI Support for the Long Term Pavement Performance (LTPP) Program

The Long Term Pavement Performance (LTPP) program is an ongoing effort to collect and understand information about how and why pavements behave as they do. The program consists of 18 experiments designed to answer specific questions about how certain variables -pavement design, construction, and materials; traffic loading; and climate- affect pavement performance over time. Pavement test sections are established throughout the United States and Canada with the cooperation and support of the state and provincial highway agencies, some in pre-existing highways and others constructed to the program’s specifications. The program has monitored the condition of these sections, their traffic loads, and climatic conditions. The data collected has been made available to the highway community. The program is the largest and longest pavement monitoring program in the world, and it has assembled the most comprehensive pavement performance database in the world. Specific to California, 45 projects consisting of 126 test sections (out of over 2500 test sections across the United States and Canada) were included in the LTPP program. Some of these projects have gone out-of-study over the years, but others are still actively monitored to achieve the project objectives. These sections are located throughout the State.
