Avaliação da drenagem superficial em pista de pouso e decolagem por meio de processamento digital de imagens

Abstract

The =repavement adherence is a major factor to minimize episodes of hydroplaning. Conven=onal texture assessment methodologies prove to be inefficient and unreliable, due to human interven=on in the test. On the other hand, the development of new technologies has provided more agile assessments through techniques such as Digital Image Processing (DIP). In this sense, this paper aims to analyze of the superficial runoff of the rainwater with evalua=on of the texture of airport coa=ngs through DIP. The field study was carriead out at an aerodromo in the state of Ceará and sought correla=ons between the Sand Patch Test and the three DIP methodologies presented. With success rates of more than 70% according to the macrotexture classifica=on, it was concluded that the pixel coun=ng method proved to be efficient for analyzing the macrotexture in situa=ons where there is a presence of water in the pavement.
