The Long-Term Pavement Performance (LTPP) Program data analysis projects takes the raw data collected from the program's more than 2,500 pavement test sections and converts them into useable information. The projects address a broad array of topics—from field validation of pavement design...
FHWA's bridge and structures research and development provides technologies and solutions to advance the state-of-the-art and practice in highway infrastructure engineering. FHWA's bridge and structures research is carried out as an integral part of FHWA's broader Infrastructure Research and...
Launched in 2014, the Long-Term Pavement Performance (LTPP) InfoPave™ web portal is the public gateway to access data and other information about the program. The web portal is designed...
Data collection and management are core functions of the Federal Highway Administration's Long-Term Pavement Performance (LTPP) Program. They are also a shared function between LTPP and the States and Provinces. LTPP maintained four regional offices—North Atlantic, North Central, Southern, and...
Below is a description of each of the Specific Pavement Study (SPS) experiments. When constructing SPS projects, States and Provinces had the option of adding sections of particular interest to them. The data for these supplemental sections are not generally available. Please contact the...
Following is a description of each of the General Pavement Study (GPS) experiments:
Sections in this experiment include a dense-graded hot mix asphalt concrete (HMAC) surface layer, with or without other HMAC layers...
The Long-Term Pavement Performance (LTPP) program monitors more than 2,500 asphalt and portland cement concrete (PCC) pavement test sections throughout the United States and Canada. A total of 934 LTPP test sections contain the common types of pavement in use in the United States (...
Federal Highway Administration's (FHWA's) pavement and materials research and development (R&D) is concerned with all aspects of highway pavement engineering and management, including: long-term performance; structural design; material testing, evaluation, specification; mixture design ...
The purpose of Human Factors research is to understand all road user behavior, to further the understanding of roadway user needs so that those needs can be incorporated in roadway design, construction, repair, and improvement. All of the Federal Highway Association’s (FHWA's) strategies for...
The primary purpose of the Safety Data and Analysis (SDA) research focus area, and the program of the same name in the Office of Safety Research and Development, is to provide information and tools to use that information for decisionmakers to maximize the benefits realized by safety initiatives...
