Water Bleeding Issues in New Asphalt Pavements

Too often, shortly after a road gets a new asphalt surface, water/moisture bleeds up through the pavement. Most of the time, it emerges through a longitudinal joint. However, there have been several instances where it comes up in the middle of a lane. In most cases, this occurs on larger facilities such as interstates, parkways, and four-lane roads, but it has occurred on local facilities as well. Generally, this problem did not exist before the introduction of Superpave mixtures. These mixtures tend to be more porous. Sometimes the issues are in a sag, but other times they are at the crest, and have been found anywhere in between. The ditch lines are always clear, and often the existing facility was built on a rock road bed. Perforated pipes are present in some cases but are always below the roadbed template.
