TRENDS IN BITUMINOUS SURFACINGS FOR AIRFIELD PAVEMENTS

Special requirements for airfields are driven by the need to design, construct and maintain airfield pavements, which will satisfy the concerns of the international aviation community over potential safety issues. In comparison to roads, airfields for both military and civil air transport are subject to much greater loads, much higher speeds, have more stringent standards of surface friction, have essentially different surface regularity requirements and higher standards for surface integrity, and are subject to more severe chemical treatments. These elements cannot be compromised in the process of harmonization of standards. Although the same materials are used in road construction as are used in airfield construction the performance requirements of airfield pavements are such that it is necessary to adopt a separate approach for the design and specification of airfield pavements to that used for roads and other trafficked areas. The four principal requirements that require special attention are: a) surface cleanliness, integrity and durability; b) friction; c) load classification; and d) roughness. The maximum Aircraft Take- Off Weights can be as high as 400 tons and the maximum single wheel load can be up to 30 tons in a triple tandem wheel configuration with tire pressures up to 3 MN/m2. Further, the speed varies from static load to velocities up to 300 km/h and the traffic frequency varies from almost no usage to much higher levels in channelized areas of runways and taxiways. Runway evenness and the associated effects of longer wavelength variations in profile on airframe dynamic response is the subject of ongoing deliberations by ICAO. Further, it is crucial that construction work on existing pavements provides long-term performance with minimal requirements for routine maintenance work. Furthermore, the binder may have to be a fuel resistant binder and the binder may have to be resistant to de-icing agents. The trends in airfield pavement technology are special requirements and use of special binders, special construction techniques and more advanced and intensive quality control.
