Whether you’re looking to deepen your understanding of profile measurement, ride quality evaluation to identify roughness, or solutions to improve initial pavement smoothness, you’ll find valuable information written for industry professionals and stakeholders. Explore our content to stay informed and make data-driven decisions for airfield pavement excellence.
This informative article breaks down the technology of aircraft simulation and illustrates how accurate it can be at identifying pavement roughness.
The Boeing Bump Index can be an effective tool to evaluate some types of pavement roughness. But, as this article illustrates, it should not be the only method used to evaluate serious ride quality problems.
This article is a collaborative effort between APR and the Greater Toronto Airport Authority and Air Canada. In it, we examine the problem of pilot reported roughness and how APR worked with the Toronto International Airport and Air Canada worked together to develop a solution.
While easy to use and understand, Ride Quality Indexes such as Profile Index or IRI usually fall short of truly identifying the ride quality of an airfield pavement. This article discusses those commonly used indexes and why they may not be as effective as you would think.
One of the most overlooked causes of surface roughness in newly constructed concrete pavements is dowel basket ripple. This article discusses the causes and how it impacts initial pavement smoothness.
Once a familiar site on an airfield construction project, the California Profilograph is getting replaced by Inertial Profilers. This paper explains why.
In the world of highway engineering, the International Roughness Index (IRI) is the go-to metric for evaluating pavement ride quality. It’s standardized, widely understood, and backed by decades of use. But on runways? IRI just doesn’t measure up.
Evaluating measured profile data for shape changes and ride quality deterioration is a logical extension of Pavement Management. This paper discusses the insights you will get when you integrate this evaluation into your PMS.
