Installing strain gages in a pavement can give useful information on pavement distress before visible marks appear on the pavement surface. The installation of sensors at existing and busy airports comes at a price, with a very short construction window, because of the need for least disruption to air traffic owing to the expensive concessions paid by airlines almost a year in advance. As such, a proposed project on a runway at Kahului airport, Maui, Hawaii could only be granted three six-hour nights, from 11 pm to 5 am, while Honolulu airport executed a project on a taxiway that has a 7-day window, on which this article will focus. Among the many constraints - both for construction and airport safety - is the requirement that concrete attain 5000-psi strength before the taxiway is reopened to air traffic. This means that the major work of concreting on the taxiway must be completed before the end of the 4th day of the construction window. Thus, scheduling must be done in 15-minute slots. In addition, precision is key, and high productivity is required. This article describes the construction method behind this unique project.
