VERY THIN ASPHALT CONCRETE AS RUNWAY WEARING COURSE. QUALITY CONTROL BY MEAN OF MICROSCOPY TECHNICS
The paper discusses the resurfacing of the wearing course of the main runway of the Copenhagen Airport. The project included the milling off of the top 20 mm of the old wearing course and the construction of a new 20 mm thick wearing course of the type where the asphalt paving machine is spreading 1.2 - 1.4 kg/square m of emulsion in front of the open graded asphalt concrete being paved. The paper describes the output of the traditional laboratory analysis as well as the output of the analysis of thin section microscopy during the four year period. The use of this pavement type has resulted in unexpected advantages and one of the unexpected advantages is that compared to conventional pavements for runways almost no rubber from the wheels of the aircraft fastens to the pavement surface thus almost no work on derubberization needs to be carried out. Another unexpected advantage is that much less deicer material is needed for the deicing of the pavement compared to traditional runway pavements.
