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

W h a t i s a n A P M S ?

An APMS is a Tool to:

3


• Identifies appropriate type of repair at optimal time

• Illustrates rate of deterioration

• Results in lowest life-cycle cost

The pavement life cycle curve:

4


• Slows rate of deterioration

• Extends pavement life in a very cost-effective manner

Effect of maintenance at optimal time:

5


• 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

6


• 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

A P M S p r o c e s s – f i r s t s t e p s

Systems inventory and network definition:

7


• 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


• 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

• Same software used in prior studies

• System calibration to reflect current conditions and FAA & WSDOT policies

• Data analysis

• PCI calculated / section PCI values extrapolated

• Analyze distresses

• Evaluate deterioration rate

• M&R needs identification (based on unlimited budget)

• Statewide analysis

• System PCI / budget scenarios / impact of scenarios / funding backlog

• Develop pavement performance models

• Establish prioritization guidelines

• Develop maintenance and rehabilitation (M&R) policies

• Unit cost information for M&R actions

• October 2017 to February 2018 – Records collection and review, airport

coordination, and review of pavement network

• Mid to late February to May - Pavement inspections

• March to August – PAVERTM customization, unit cost development, performance

modeling, maintenance policy development

• August to October – Analysis and M&R program development

• November 2018 to February 2019 – Reports and IDEA development
