If you’re a pavement engineer, civil engineering student, or researcher working on airport and highway pavement design , you have almost certainly heard of IITPave .

A common Google search is: “Download IITPave Software.” Let’s break down the reality of downloading it, installation challenges, and the modern alternatives. Short answer: Not officially from the FAA or IIT anymore.

Instead, download directly from the FAA. It’s free, safe, up-to-date, and accepted for real-world airport pavement design. If you need IITPave only to check an old design, run it inside a Windows XP virtual machine using a trusted backup copy.
