Below is a list of some of our most recent customers and sample projects we have completed for them. For a complete list of our customers and point of contact information for each project, please contact us.

Port Authority of New York and New Jersey
APR has worked with the Port Authority since 1995 to take a proactive approach toward runway roughness. Runways at all four airports are measured periodically and any changes in the profiles are noted. In addition, APR measured recently rehabilitated pavements in order to obtain a baseline profile and an initial ride quality assessment. APR has for many years, provided all types of smoothness related services for the Port Authority. These include pavement management, new pavement acceptance, evaluation of pilot reported roughness, assistance in pavement design, recommendations for repair strategies and more.

Hartsfield Atlanta International Airport
APR has been working with the Hartsfield Atlanta International Airport since 2000 to evaluate all of their runways for smoothness and ride quality. In 2004, APR worked on a project to develop smoothness acceptance criteria for two new taxiways.

Hong Kong International Airport
Since 1998, APR has been working with Hong Kong International Airport to evaluate the ride quality of their runways. Profile measurements have been taken each year, and the runways have been evaluated using the same methods. APR has not only been able to track all changes in the pavement’s profile, but also to find any areas where the changes could significantly impact aircraft response.

Cincinnati International Airport
Since 2001, APR has worked with Cincinnati International Airport to evaluate their runways for ride quality. APR measures and analyzes one runway each year on a rotating basis to track any changes.

Indianapolis International Airport
In 2003, APR was contacted by Jim Thomas of the Harper Construction Company, of Hebron Kentucky. Harper had paved Taxiway B at the Indianapolis International Airport based on a design created by another contractor. The designing contractor indicated that the pavement did not meet the specifications in certain areas. APR was hired by Harper to evaluate the ride quality of the affected areas. APR’s conclusions were that these areas were acceptable from a ride quality perspective. The taxiway was then accepted by the designer and the airport authority.

Orlando International Airport
In August of 2003, APR analyzed a new runway at Orlando International Airport. When the new runway was complete, the airport authority found that it did not meet California Profilograph specifications. Because of this, the Federal Aviation Administration questioned the quality of the new pavement. APR was hired to analyze the pavement and rate it with respect to simulated aircraft response. Prior to APR’s analysis, the paving contractor had already done some grinding in an attempt to repair areas that were out of specification. APR analyzed the pavement and found it to be smooth with only small areas of exception. APR concluded that the pavement was acceptable. The runway was then accepted for service.

Aeroporto Di Genova
In January of 2004, APR analyzed a runway at Aeroporto Di Genova in Genoa, Italy. This process entailed acquisition of the profile in Genoa as well as a full analysis with repair recommendations. This runway was a known rough runway that caused poor aircraft response that led to pilot complaints. APR was hired to pinpoint the areas on the runway that were causing the roughness in order to minimize repair cost to the airport. APR was able to locate several areas that contained multiple bumps and dips in a row (multiple event roughness) that were causing moderate aircraft response. APR’s final report included a pavement smoothness chart with each 500 foot section rated on a scale of 0 to 100. APR recommended repairs to particular areas that would reduce aircraft response and result in a more desirable smoothness.

Lester B. Pearson International Airport
In 2002 and 2003, APR performed a baseline ride quality analysis for all 5 of Toronto’s Lester B. Pearson International Airport’s runways. This service included three lines of survey of each runway measured with APR’s AR&L profiler. These longitudinal profiles will serve as historical references for any future ride quality analysis as well as for pavement repair considerations. With the profile measured, APR conducted its standard ride quality analysis. This analysis consisted of performing takeoff and landing simulations. This process predicts the aircraft’s response to the measured pavement profile during these standard aircraft operations. A VSweep analysis was also conducted on each runway to characterize the ride quality of the entire runway, not just the portions used in takeoff and landing operations. Finally, a series of straightedge analyses (SEA) were conducted to compare these pavements against existing criteria, the ICAO 3-meter straightedge, and against a straightedge that represents the dimensions of a commercial aircraft (30-meter straightedge). APR completed this work and provided the Greater Toronto Airport Authority with a report for each runway documenting the findings of the analysis.

Fargo International Airport
In 2004, APR worked with Fargo International Airport to measure and analyze a newly constructed runway. This also involved analyzing the arresting cable barriers on each end of the runway (Air National Guard aircraft) to ensure smoothness.
