  1. 10-Year Airport Pavement R&D Plan Airport Pavement Working Group Gordon Hayhoe, ANG-E262 Sheraton Atlantic City Convention Center April 25, 2012

  2. 10-Year Plan Outline • Current Status. • Areas of Work. • Software Development. • Non-destructive testing. • Materials and construction.

  3. Current Status • Since publication of the first airport pavement R&D plan in 1993, a comprehensive collection of airport pavement design and evaluation computer programs have been developed. • Development of the computer programs was supported by analytical and full-scale test work.

  4. Computer Programs Since 1993

  5. Ancillary Computer Programs • ConvertProfileFormat. • Profile32. • ProGroove. • 10-View. • NAPTF test vehicle control.

  6. National Airport Pavement Test Facility • CRDA with Boeing, joint funding and test plan development. • Working group support and assistance. • Primarily used to develop structural failure models for pavement thickness design procedures. Six major construction cycles completed to date.

  7. Primary Areas of Work in New 10-Year Plan • Pavement design, evaluation, and management software. • Life cycle cost analysis. • Non-destructive testing. • Materials and construction processes. • NAPTF. • Field testing • High Temperature Pavement Test Facility.

  8. Area 1. Software • Except for PAVEAIR, and a couple of others, the existing programs are considered to be technically mature. • All require normal maintenance and adjustment to new pavement and computer technologies. • Most require updating to the latest programming environments and operating systems. • Integration of the programs and data structures is required. • Web-based interoperability would be nice.

  9. Relationship Between Main Programs

  10. Software Structures • We are committed to further development and maintenance of computer program applications. • PAVEAIR is considered to be the “hub” application and should be the depository of almost all data required by the other programs. • Current thinking is that the “satellite” programs should remain as individual applications linked to PAVEAIR by specialized services or other data pathways.

  11. Software Structures (continued) • All programs, including PAVEAIR, should be capable of being run stand-alone on individual personal computers. • All programs should be capable of communicating with PAVEAIR over the internet.

  12. Software Structures (continued) • Different levels of integration. • FAARFIELD, COMFAA, and BAKFAA should share pavement structures. • FAARFIELD and COMFAA should share aircraft mixes. • ProFAA should probably be almost completely independent, unless profiles are stored by PAVEAIR.

  13. Software Development Models • All programs except PAVEAIR were developed in VB 6.0. • VB 6.0 is no longer supported by Microsoft and all programs must be translated into .NET applications, including all ancillary programs. • Windows 7 should be the target operating system. The future of Windows 8 is not clear.

  14. Software Development Models • PAVEAIR is an ASPX web application and will remain so. • FAARFIELD and BAKFAA have been translated from VB 6.0 into VB.NET Windows Forms applications. • ProFAA is being translated from VB 6.0 into a VB.NET Windows Presentation Foundation application.

  15. Windows Forms • Windows Forms is the traditional Microsoft Windows software model. • It might not be developed significantly beyond its current state. • It is strictly a single computer software model. • Communication over the internet is difficult (consider the 1-Click distribution model).

  16. Windows Presentation Foundation • Windows Presentation Foundation (WPF) is an alternative Windows software model with potential to displace Windows Forms for single computer use and allow a path to conversion to web-based applications. • Features of WPF distinct from Forms are:

  17. Features of WPF distinct from Windows Forms • User interface and application code bases are almost completely separate (XAML versus VB). • Automatic component resizing is built in. • Can be compiled as a browser plug-in with reduced functionality. • Can be translated to a Microsoft Silverlight application with reduced functionality with manageable effort.

  18. Microsoft Silverlight • Silverlight is Microsoft’s version of Adobe Flash. • Can be compiled as a true single computer application or a true web-based application (plug-in) by changing only a couple of lines of code. • Need to decide which model to use very soon.

  19. Life Cycle Cost Analysis (LCCA) • Over 100 pages in AC 150/5320-6E. • 4 ½ pages are devoted to LCCA. • 300 pages in AIP Handbook, Order 5100.38C. • 1 page is devoted to LCCA methodology. • This is not enough to provide guidance when jobs are bid based on LCCA.

  20. Life Cycle Cost Analysis (continued) • Modify the AAPTP AirCost Excel application to communicate with PAVEAIR. • Run cost analyses and determine the data requirements to begin defining standard procedures for airport pavement LCCA. • This will require expert help from engineering economist consultants.

  21. Non-Destructive Testing • After software development, non-destructive testing is seen as the next most important work area. • The objective will be to improve the predictive capability of PAVEAIR.

  22. Improve the Efficiency of Pavement Condition Surveys for More Frequent and More Comprehensive Inputs • Automated equipment for data collection. • Crack surveys. • Roughness profile measurement. • HWD, RWD, GPR.

  23. Improve the Efficiency of Pavement Condition Surveys for More Frequent and More Comprehensive Inputs • Automated software applications for data processing. • Crack detection. • Crack characterization. • PCI from crack surveys. • ProFAA. • PCN and load evaluation. • Groove measurement and evaluation.

  24. Vehicle for Evaluation of NDT Equipment and Software
