Pavement Smoothness Requirements
Historically, many states used a profilograph specification for measurement of pavement ride quality for construction purposes. Although this was an effective tool, the technology is over a half century old and IPS technologies are more accurate and more efficient and it should be the goal of all agencies to convert to IPS measurement systems.

Pavement Smoothness Index Relationships
The profilograph is widely used to measure and control initial smoothness by producing profile traces, which can be evaluated to identify severe bumps and to establish an easily understood, overall measure of smoothness, the profile index (PI). However, concerns about the accuracy of the profilograph have grown significantly in the last decade.
