Ames Engineering is at the forefront in the development of sensor technology for pavement measurements. Over the years, we have worked side-by-side with the paving industry and government agencies to develop systems that yield exceptional data accuracy and performance. Recent research reports are listed below, and we invite you to review them.


ACPA Profiler Repeatability 2005

We at Ames Engineering understand that the purchase of a road-profiling device can be an expensive and confusing proposition. Published device comparisons can be difficult to find and understand, particularly when it comes to the issue of textured surfaces. In 2005 the American Concrete Paving Association (ACPA) funded a study conducted by the University of Michigan Transportation Research Institute (UMTRI). UMTRI has been involved in transportation research issues for over 40 years and has been very involved in the development of improvements in road profiling technology. In this study, manufacturers of profiling equipment were invited to test their equipment on four different textured concrete road surfaces. Four manufacturers participated in collection of test data during this study and the results have been published. We encourage you to read this report and make your own informed decision.

FHWA Reference Profiler Research Study at MN Road 2007

Last fall the Federal Highway Administration sponsored a study researching the accuracy and repeatability of reference profilers at the Minnesota Department of Transportation's research facility in Albertville, MN. Ames Engineering was invited to participate in the study with our lightweight profiler equipped with a TriODS and RoLine sensor. The results of the study show the TriODS and RoLine sensor have excellent accuracy and repeatability with two of the reference profilers. These continued strong results of Ames Engineering profilers again demonstrate how well we achieve the highest level of quality for our customers. Please take a few minutes to read through the FHA's full report listed below.
