Pavement Condition Index

Pavement Surface Type

This map shows the surface pavement type of the airport. Three yellow boxes show the image data collected during pavement inspection including a small description. Each image is a sample of a group of photos representing a section of pavement-named branch. Each branch has a unique number to represent that section in the database and in the coverages. After the pictures are taken and analyzed, the resulting information is entered into the MicroPAVER program. This gives the pavement condition index number. The branch numbers are joined from the database to the pavement shapefiles using the branch field. This enables the creation of pavement maps including the Pavement Condition Index map.

Pavement Condition Index

This map depicts the condition of pavements rated 0 to 100. The ratings are grouped into seven categories: failed, very poor, poor, fair, good, very good, and excellent. After the pavement database is joined to the shapefiles, the map can be symbolized using any information produced from the results of the data and the results of the analysis. Among many other uses, the data and maps are used to plan the construction budget, pavement replacement, rehabilitation, and concrete pavement joint seal replacement program.

All the pavement geospatial data in this project is maintained in two separate coverages. These coverages are laid out on arbitrary and separate grid systems based on runway centerlines. The grids were created many years before computerized GIS. For design and records retention, it is necessary to continue to maintain the data in these grid systems. When it is time to create the pavement maps, ARC Macro Language (AML) is run, which places these two grids in state plane NAD83 surveyor foot. At that point, the two coverages come together for the first time. ArcMap is used to create these maps by converting the coverage to shapefiles.
