Abstract:
Airports are vital national resources. Airfield Pavements within an airport
represents a large capital investment in infrastructural development made by a
country. Timely and appropriate maintenance and rehabilitation of such in-service
facilities are essential to provide an all-weather surface for safe and regular operations
of the aircraft. Pavement maintenance is done based on functional and structural
pavement condition evaluation. This paper presents a case study dealing with functional
evaluation of airfield pavements of a small sized airport in India. The considered
airport consists of two runway, seven link taxiways, three apron areas and an isolation
bay with different surface types. Present paper reports the methodology adopted for
the functional condition evaluation of the airfield pavements with help of Automated
Road Survey System. Further, the evaluated pavement condition was quantified in
terms of Pavement Condition Index (PCI) as per the ASTM D5340 with help of
PAVER and GIS based software. GIS was used for preparing inventory database and
basemaps for the concerned pavementswhich were then used in PAVER software for
determining the PCI. The airfield pavement network within the airport was divided
into a four-level hierarchy consisting of the network, branch, section and sample.
The obtained PCI rating shows that the overall condition of the airfield pavements
within the considered airport is satisfactory to good, however some of the areas have
distresses that needs to be repaired by localized maintenance.
