Airport pavement is a large area, wide distribution structure. Dividing the pavement up into smaller,
more controllable units is an important component in the APMS process [4]. The purpose of pavement
division is to provide spatial reference position and assure the comparability of pavement evaluation. As
specified in CAAC MH/T5024-2009 [5], the definition of network is comprised of three main divisions:
branch, section, and survey unit.
Airport pavement is divided up into several branches. A branch is comprised of an entire segment of
infrastructure such as a runway or taxiway. In SHAPMS, the airside pavement was subdivided into three
types of branches based on functional classification: runways, taxiways and aprons.
The next stage of division is critical to the proper functioning of SHAPMS. Using the existing
pavement inventory and engineering drawings, each branch is broken into smaller components called
“sections”. A section must have uniform design, construction history, traffic, and condition.
The final step in the pavement division process is to split each section up into survey units for
inspection and evaluation purposes. As stated by the CAAC MH/T5024-2009, the sample unit size for
airfield pavements are 20 ± 8 slabs for each Portland cement concrete (PCC) pavement unit and 450m2 ±
180m2 of area for each Asphalt concrete (AC) pavement unit.
After the completion of pavement division, each branch, section, and survey unit should be identified
by a unique ID. The ID is a unique code used to help store and retrieve data from the spatial database.
