The Perfect Mix

A runway reconstruction project at Boston-Logan International Airport posed some unique and formidable challenges. This article describes this project. Testing had determined that, in many areas, layers of the hot mix asphalt pavement beneath the surface course had been stripped of asphalt, causing ruts, cracks, delamination and shoving throughout the runway. The extent of the distress and the degree of asphalt stripping made total reconstruction necessary. To prevent the same damage from occurring again, a custom-made mix of bituminous materials was used that allowed for more tailored reconstruction of the differing conditions throughout the runway. Logan's integrated taxiway configuration, limited runway capacity and a short construction season which coincides with a high travel season made the project even more difficult than a normal runway reconstruction project. The team worked 12-hour extended shifts around the clock for 6 weeks to get the runway back in service quickly. While the project took about 3 months to complete, the runway itself was closed for only 28 consecutive days. The new asphalt mix seems to be performing well and is being evaluated by both Logan and the Department of Transportation for use in future projects.
