Paper Abstract

The deterioration of asphalt pavements and airport runways is one of the most serious problems concerned with materials engineering, transport engineering and transportation in general. Usually, this is done to the lack of knowledge or even in the lack of commitment, the maintaining such structures. When failure occurs in an airport runway or in an asphalt pavement, reconstruction is expensive. Therefore, cost-effective ways must be suggested, in order to see how badly deteriorated the investigated structure is. One of these cost-effective ways is the infrared thermography technique. This technique is used successfully in the detection of cracks, surface voids and other anomalies appearing from the aging of such materials. In this research work, by using an infrared thermographic system (AVIO TVS 2000 Mk II LW, wavelength 8 - 12 micrometers ), and with the aid of liquid diffusion, an investigation of asphalt pavements and airport runways situated in Greece was performed. The results of this investigation have led to the design of a monitoring and control NDT system for the inspection of the defected areas of the airport runways and asphalt pavements and consequently the appropriateness of distinctive engineering structures.
