Web-based access for your pavement management data and recommendations
Training in pavement evaluation and the use of the PAVER software.
APTech develops Interactive Data Exchange Applications (IDEAs) for many clients. These programs combine the use of maps, photographs, and links, allowing the viewer to quickly identify pavement conditions and needs at a specific airport or throughout the state. These programs can be run directly from a CD or easily hosted on a website.
In 2016, APTech was awarded a 5-year contract with the Colorado Department of Transportation (DOT) Division of Aeronautics (Division) to provide pavement evaluation and pavement management services for airports statewide. This project continues a relationship with the Division that extends back to 1996. Since then, the Division has relied on APTech to assist in the proactive management of the pavement infrastructure at the airports. A key to the success of this long-term relationship has been the partnership between APTech and the Division in this effort to preserve the Colorado airport pavement infrastructure in the most cost-effective manner possible.
Most years, an APTech engineer teams with Division staff members to perform the pavement evaluations at one-third of the sixty-three airports. The Division further assists with the process by obtaining systems inventory information pertaining to pavement maintenance, rehabilitation, and construction at the project airports. To increase efficiency and reduce costs, APTech uses handheld computers during the collection of field condition data. This allows the pavement evaluation data to be entered directly into the pavement management database and analyzed in real-time. In close collaboration with the FAA and the Division, APTech integrates the recommendations for pavement maintenance and rehabilitation developed during the APMS process into the FAA’s Capital Improvement Program.
During the 2010 update, APTech developed a web-based Interactive Data Exchange Application (IDEA) for the Division, which replaced individual airport reports. It presents instant access to the most commonly requested pavement management information – such as pavement condition index data and maps, distress photographs and quantities, and maintenance and rehabilitation options – without requiring the user to obtain and operate the pavement management system. This program can be viewed at: https://www.codot.gov/content/programs/aeronautics/PCI/
APTech has updated the APMS for the Michigan Department of Transportation Office of Aeronautics since 2005, being reselected in 2009 and 2013, with the most recent round of updates completed in May 2016.
The APMS included a total of ninety-six airports. APTech used the Pavement Condition Index (PCI) procedure to evaluate the airports' pavement and the data were used to update the Office of Aeronautics' PAVER pavement management system. After each project year, APTech determined current and future pavement conditions and developed maintenance and rehabilitation (M&R) recommendations for this extensive pavement system.
To ensure that the Michigan APMS data would always be readily accessible to everyone who needed it, regardless of their technical background, APTech developed a web-based IDEA that was updated after each round of pavement inspections.
Over the years, the Office of Aeronautics has been so satisfied with APTech's work that is awarded APTech with the Michigan DOT Bureau of Aeronautics and Freight Services' Consultant of the Year award in 2009 and again in February 2015.
The Phoenix Sky Harbor International Airport has an extensive pavement network, which represents a major infrastructure investment to the City of Phoenix (City). In order to protect this investment, the City contracted with APTech to develop a pavement maintenance management program (PMMP) that will allow the pavements to be managed in a cost efficient manner.
To develop the PMMP, APTech conducted an airfield pavement assessment which included a records review, mapping, PCI inspections, PAVER database customization, and developing APMS reports. The data collected during the assessment was used to determine maintenance and rehabilitation (M&R) needs and to develop the PMMP. APTech performed the PCI inspections on the runways and taxiways at night so as not to interfere with regular traffic at the airport.
In addition to the mainline pavements, APTech incorporated the shoulders, blast pads, and infield pavements into the APMS. APTech also performed a cursory visual evaluation and providing general M&R recommendations for the airside service roads.
APTech performed nondestructive testing (NDT) using its falling weight deflectometer (FWD) on select airfield pavement, such as those identified during the PCI inspections as requiring further investigation. APTech also developed Pavement Classification Numbers (PCNs) for the airside pavements in accordance with the requirements in Federal Aviation Administration (FAA) Advisory Circular 150/5335-5B, Standardized Method of Reporting Airport Pavement Strength – PCN and FAA’s COMFAA software. The resulting PCNs were converted to allowable loads for each gear type (single, dual, dual tandem, and so on) using the FAA’s supporting spreadsheet.
Finally, APTech developed an IDEA program, which is an interactive web-formatted program used to disseminate the results and recommendations of the pavement management update without requiring knowledge of the use of PAVER.
With seventeen passenger airlines serving over 36 million passengers a year, Detroit Metropolitan Wayne County Airport is the seventeenth busiest airport in the United States. As such, the preservation of the pavement infrastructure at Detroit Metro Airport is of critical importance for the safety of aircraft and the efficient movement of air traffic throughout the region and the country. In 2008, 2010, and 2013 APTech served as the prime consultant to update the APMS, which allows the Wayne County Airport Authority (WCAA) to proactively manage their pavement assets. This work built on a 2004 project where APTech led the inspections as a subconsultant.
The 2008 project included performing PCI surveys on the new Runway 4L-22R complex, the McNamara Terminal Apron, the L.C. Smith Terminal Apron, and several de-icing pads. Runway 3R-21L and portions of the adjacent connecting taxiways were reconstructed in 2006 and 2007 and were also updated in the database. As a result of this effort, WCAA had a complete database incorporating all airfield pavement sections. In addition to conducting pavement inspections and determining the PCI of the pavements, APTech developed pavement performance prediction models to predict the condition of the pavements through 2013. The all-encompassing APMS was used to cost-effectively plan future M&R needs at the Airport.
In early 2009, WCAA had an urgent need to assess the condition of Runways 4R-22L and 3L-21R to evaluate the immediate need for major rehabilitation. APTech inspected these pavements in March 2009 and incorporated the results in the PAVER pavement management database and report.
Due to WCAA’s satisfaction, APTech was again selected in 2010 to update the APMS. This project included conducting PCI inspections on Runway 9R-27L and the majority of the taxiway system at Detroit Metropolitan Wayne County Airport. Recent and ongoing construction projects on Runways 9L-27R, Runway 3L-21R, and Taxiway Z were also incorporated into the database. In addition, the entire airfield pavement at Willow Run Airport was inspected and incorporated into a separate PAVER database. For both airports, APTech again determined PCIs for each pavement section and developed performance models to predict the pavement condition over the next 5-years. APTech also provided training on the use of PAVER to WCAA staff.
In 2013, APTech was again selected to update the APMS at both Detroit Metropolitan Wayne County Airport and Willow Run Airport. In addition to the services performed as part of previous updates, APTech will also be performing FWD testing, overseeing a geotechnical investigation, and calculating PCNs for both airports.
