New test uses drilled hole to assess cracking resistance in airport asphalt

Although the stresses and demands on roads and airport runways are very different, the methods used to analyze the asphalt they are made from are very similar. Several dedicated methods exist to analyze road asphalt, but no standardized methods exist for airport pavements. Researchers in The Grainger College of Engineering at the University of Illinois Urbana-Champaign have now developed a simpler, practical test and analysis for airport asphalt pavements.
