Washington Airport Pavement Management System (APMS)
• Provide fact based data
• Maintain an inventory of the pavement system
• Assess the relative condition of pavements
• Monitor pavement condition
• Identify pavement-related needs
• Prioritize pavement-related work
• Assist in selecting the most cost-effective repair strategy, short- and long-term
• Track performance of selected treatments
• Communicate funding needs
• Measure system performance

Washington Airport Pavement Management System (APMS)
• Originally implemented in 2000 - updated 2005/2006 - 2012/2013 – 2017/2018
• Includes approximately 100 airports
• Assists airport sponsors in complying with state and federal grant assurances
• FAA grant assurance 11 (NPIAS airports)
• WSDOT grant assurance 12 (NPIAS and Non-NPIAS airports)
• Fulfills the requirements of Public Law 103-305 for NPIAS airports
A P M S B a c k g r o u n d
Washington’s APMS:
Public Law 103-305Authorizes the Secretary to approve the
replacement or reconstruction of pavement at an airport only if the sponsor has provided
assurances that such airport has implemented an airport pavement
maintenance-management program.
FAA Grant Assurance 11…assures or certifies that
it hasimplemented an effective
airport pavement maintenance-
management program
WSDOT Grant Assurance 12…assures or certifies to the
department's satisfaction that it has implemented an effective airport pavement maintenance-management
program

Washington Airport Pavement Management System (APMS)
• Review existing airport inventory information
• Records review of pavement work completed since prior study
• FAA and WSDOT Grants
• Construction records
• Airport Layout Plans
• Communications with airports and/or consultants
• Update pavement management database
• Network definition (network, branches, sections, sample units)
• Prepare network definition maps

Washington Airport Pavement Management System (APMS)
• Airports grouped geographically for logical site visits
• Airport sponsors contacted prior to inspection
• No lengthy facility closures
• Visual inspection – no destructive testing
• Pavement distresses documented (type, quantity, severity)
• Pavement section photographs, geo-referenced, and labeled
• Results entered into pavement management database
A P M S p r o c e s s – n e x t s t e p
Pavement evaluation:
8
Washington Airport Pavement Management System (APMS)
• Pavement Condition Index
• Aviation industry standard methodology used to objectively evaluate pavement
• Documented in FAA Advisory Circular 150/5380-6B / ASTM D5340-11
• Consistent, objective, and repeatable
• Characterizes pavement defects (distress)
• Type / Severity / Quantity
• Composite index of overall pavement condition in numerical terms ranging from
100 (excellent) to 0 (failed)
• Indicative of the level of work required to maintain or repair a pavement
• Provides insight into cause of deterioration
