PAVER development is supported by thefollowing agencies: US Air Force, US Army, USNavy, Federal Aviation Administration, and theFederal Highway Administration.PAVER provides pavement managementcapabilities to: (1) develop and organize the pavementinventory; (2) assess the current condition ofpavements; (3) develop models to predict futureconditions; (4) report on past and future pavementperformance; (5) develop scenarios for M&R based onbudget or condition requirements; and (6) planprojects.The following is a brief overview of PAVER components and capabilities.About – PAVER 7PAVER inventory management is based on ahierarchical structure composed of networks,branches, and sections, with the section being thesmallest managed unit. This structure allows users toeasily organize their inventory while providingnumerous fields and levels for storing pavement data.Other features included in Inventory: User-defined Fields: In addition to the standardinventory information, users can define their ownfields to meet their management requirements. Virtual Inventory: Allows the user to create virtualcopies of the existing inventory and group sectionsfor easy presentation. Surface Change: Automatically calculates andupdates pavement surface based on work historyinformation. Edit Historical Inventory: Easily edit historicalinventory values associated with previousinspections.2
recording the results of an inspection and an HTMLdistress user guide, as shown in Figure 2.InspectionTo assess pavement condition, PAVER uses thePavement Condition Index (PCI) as its primarystandard. The PCI measures pavement condition on ascale from 0 to 100. ASTM has adopted the PCI asstandard practice for roads (D6433-11) and airfields(D5340-11). PAVER allows users to customize PCIcondition rating categories, as shown in Figure 1.PAVER also provides the user an interface forDistressTypeIn addition to the PCI, PAVER allows managers touse and create other condition indices, including thosebased on PCI distresses. An interface easily importsinspection data from automated vehicle collectionsources.There is also a wizard for creating and 25DistressSeverity100Standard PCIRating ScaleGood100Custom PCIRating ScaleDark GreenGoodSatisfactoryBright GreenFairYellowPoorRoseVery PoorLight RedSeriousDark RedFailedGray7055FairPoor0Figure 1: Pavement Condition Index (PCI) ranges may be customized and used for reporting analysis results.Figure 2: The online distress user guide can be opened within PAVER by clicking on theinformation button.About – PAVER 73
Prediction ModelingThe Prediction Modeling function in PAVER helpsidentify and group pavements of similar constructionthat are subjected to similar traffic, weather, and otherfactors affecting pavement performance. Pavementcondition historical data is used to build a model thatcan accurately predict the future performance of agroup of pavements with similar attributes, see Figure3.Work PlanningThe PAVER Work Planner is a tool for planning,scheduling, budgeting, and analyzing alternativepavement maintenance and repair (M&R) activities.The Work Plan has been optimized for greater speedand is more than 100 times faster with large databasesthan previous versions.PAVER 7 uses M&R Families. Sections areassigned to M&R Families to establish groups ofpavements which use different pavement cost tables orreceive similar types of M&R work. The WorkPlanner uses M&R Families along with inspectiondata, maintenance policies, maintenance costs, andpredictions of future pavement conditions torecommend M&R activities at the section level.Figure 3: Pavement “family” models can be developedto predict future pavement condition.Condition AnalysisThe Condition Analysis feature allows users to viewthe condition of the entire pavement network or anyspecified subset of the network. This feature reportspast conditions based on prior interpolated valuesbetween previous inspections and projected conditionsbased on prediction models. In PAVER , conditionscan be viewed on GIS maps in addition to tables andgraphs, see Figure 4.Figure 4: Internal GIS can be used to display pavementcondition and analysis results. For example: ConditionAnalysis and Work Planning outputs are displayed in GIS.About – PAVER 7PAVER 7 also supports credit for global work afterthe latest inspection.The PAVER work plan provides two ways toanalyze budgets scenarios. The first way determinesthe consequence of a selected budget on pavementcondition and the resulting backlog of Major M&R(unfunded). In addition to a single budget scenario,PAVER 7 offers a budget split feature. The budgetsplit feature allows the user to split a budget based ondifferent M&R work types. This can aid a user that hasa set budget for Global work and a different set budgetfor Major work. The second way determines thebudget requirements to meet specific managementobjectives, i.e. backlog elimination or PCI goal. Thisenables managers to develop a variety of fundingscenarios to support their decisions, see Figure 5.Figure 5: Work planning enables users to determine howmuch funding is required to meet management objectives,such as maintaining current PCI or eliminating backlogs.4
Project PlanningThe Project Planning tool, included in the M&R Plan,allows the user to develop projects based on userspecified required work and PAVER recommendedwork. This tool greatly aids the user in planningprojects and automatically updates work history dataupon completion of the project, see Figure 6.GIS Assignment ToolThe GIS Assignment tool links the PAVER data forindividual pavement sections to GIS data. The GISAssignment tool provides an internal “point-and-click”interface to create, remove, or change the link betweenpavement sections and GIS map features.Using the same visual layout as Selectors, Figure 8,the tool dramatically reduces the time required tocreate or change the link between GIS and pavementdata. It is designed to work directly with the sameshapefiles that are used in PAVER ’s internal GIScapabilities.Figure 6: Project Planning allows the user to planprojects based on recommended work analysisand installation management priorities.GIS InterfacePAVER includes internal mapping capabilities toview GIS reports directly in PAVER . PAVER also produces shapefiles of reports, such as inventory,inspection, condition analysis, and work plan, whichcan be viewed in commercial GIS software.Selection ToolsPAVER 7 offers an improved user interface. Toolsassist users in selecting pavement sections. GIS andtree based selection tools provide additional methodsfor selecting inventory items throughout PAVER .For example, inventory and inspection screens willdisplay the selected pavement section for data viewingor editing, as shown in Figure 7.Figure 8: The GIS Assignment Tool links the PAVER data for individual pavement sections to GIS data.Selection Criteria Available on ExportPAVER 7 allows a user to share a subset of aninventory, which the user controls using selectioncriteria in the export process.XML ImportThe user may import XML files from other programswhen they conform to the published XML importformat. PAVER FieldInspector and PAVER ImageInspector are two such programs.Optimization for Large DatabasesPAVER 7 has been optimized to handle largedatabases (10,000 sections). It is highlyFigure 7: GIS and tree based selection tools provideadditional methods for selecting inventory itemsthroughout PAVER .About – PAVER 7recommended that the user have PAVER 7installed on a 64-bit computer and use a SQL Server(Express) database.5
XML format, the wizard guides the user throughthe import process. This wizard also provides dataverification to insure that survey information isbeing imported properly into the database.WizardsWizards assist the user by providing a step by stepprocess for several common tasks. Last Construction Date Wizard determines themost recent construction date for selected sections.The wizard conducts the calculation according to aspecified deterioration rate, and discards anyinconsistent data. Set Properties Wizard updates or clears aspecified inventory property for selected sections.This wizard is limited to inert properties which donot affect the PCI calculations or predictionmodeling of family models. Split Section Wizard separates Sections into adesired division of subsections that can beanalyzed individually using any tool in PAVER .PAVER 7 SupportNon DoD: Define Inventory from GIS/Tabular Dataallows a user to create an Inventory using theattributes of the shapefile.
