LTPP Body of Knowledge
A search tool that makes InfoPave’s 1,500+ technical documents easier to navigate and understand, so users spend less time digging and more time applying what they find.
LTPP InfoPave is the Federal Highway Administration’s web-based portal providing access to the world’s largest pavement performance monitoring program, collecting research-quality data from over 2,500 in-service highway test sections across the United States and Canada. At the heart of the platform is the LTPP Body of Knowledge — a comprehensive repository of thousands of operational documents, data collection guides, test protocols, research reports, and technical briefs that form the backbone of over three decades of pavement research.
The LTPP Body of Knowledge changes that by letting users ask questions in plain language and receive tailored, relevant answers drawn directly from across the library, complete with source references and direct links to the specific pages within documents where the information appears, putting the right research in front of the right person, instantly.
Search Smarter Across a Massive Library
With over 1,500 PDF documents spanning decades of pavement research, finding the right resource used to mean hours of manual searching. Now just ask a question and let the assistant pinpoint exactly what you need across the entire library, in seconds.
Unlock Content That Was Previously Hidden
Many documents in the library are scans or image-based files that traditional search tools simply can’t read. Through advanced OCR processing and human review, the assistant captures text, tables, and figures from even the most difficult documents making the full library truly accessible for the first time.
Go From Finding to Understanding
It’s not just about locating a document it’s about getting value from it. The assistant helps you understand what publications contain, surfacing relevant findings and context so you can quickly apply research insights to your real-world pavement decisions.
