The evaluation of airfield pavements in light of applicable normative documents

Abstract

Airfield pavement evenness is, according to applicable normative documents, one of the basic operating parameters, which characterize each airfield functional element. Evenness, in fact the lack of it, determines not only comfort of aircraft movement along an airfield pavement, but also influences the magnitude of the dynamic impacts on the pavement, hence, the safety of air operations. In addition, evenness condition changing as a result of aircraft operation, adverse weather conditions or inappropriate airfield pavement construction technology leads to deviations from the desired condition in the form of longitudinal and transverse unevenness. Pursuant to the applicable normative requirements, measurements on airfield facilities can be executed using a planograph or a staff and a wedge. The used measuring devices differ from each other in terms of dimensions and permissible single unevenness. Regular and correct execution of tests is a very important factor improving air operation safety, but also enabling the designation of zones (areas) with quicker pavement degradation. If the obtained measurement data is not sufficiently reliable, they may consequently lead to making incorrect decisions, which can ultimately impact the safety of air operations.
