NCHRP stands for which program?

• A. National Extension for Highway Research Program
• B. National Cooperative Highway Research Program
• C. National Center for Highway Research Programs
• D. New Construction and Highway Rehabilitation Program

Answer: (B)

Understanding how highway research programs are named helps identify the correct expansion. NCHRP stands for National Cooperative Highway Research Program. It’s a nationwide effort funded by state departments of transportation in cooperation with AASHTO and administered through the Transportation Research Board. The term “Cooperative” highlights the joint effort among many states, while “National” signals its country-wide scope, and “Highway Research Program” describes its focus on practical, applied highway research to support planning, design, construction, and maintenance. The other options use terms that don’t match the official title—for example, “Extension,” “Center,” or “New Construction and Highway Rehabilitation” describe activities or institutions rather than the program’s name.
