| dc.description.abstract | Pavement distresses at airports are expensive to repair. Moreover, the longer a distress goes unchecked, the worse its effect is, whereas design improvements have potential in pavement management. Normal distresses cannot be eliminated, perhaps only mitigated. With this in mind, a real-time study is underway to monitor distresses in a taxiway. Early detection of distress before it is visible on the surface can potentially inform on impending pavement repair. Specifically, it is seen that there is delamination between the three-inch surface layer of pavements and the underlying base layer. If left unchecked, this results in major visible slippage, shoving, and cracking. To install early detection sensors to measure delamination is an involved task: the pavement needs to be cordoned off, the surface must be milled, sensors installed, and a trench dug to take the wires from the sensors off the runway to a data acquisition center, resting on a concrete pad. The wires must be pulled, and then the trench and milled area must be covered back with concrete and asphalt respectively. On the face of it, these tasks are elementary, but compounding them is the narrow construction window available. The challenge here is to undertake the tasks at high speed within only three work days because airport taxiways, let alone runways, cannot be kept closed for long durations. The purpose of this report is to describe the construction methodology for strain gage installation in an airport runway/taxiway. | |
