Abstract: Escalating costs of construction and maintenance have necessitated innovations that will affect cost savings. Increases in the cost of pavement restoration in New England over the past twenty years have been dramatic. In the late 1960s, an Eastern Massachusetts based contractor began experimenting with an infrared heater to soften and rework bituminous concrete. Early results were beyond initial expectations. The use of the process spread rapidly. Unfortunately, many infrared units ended up in the hands of poorly trained operators and the acceptance of this method of restoring pavement quickly deteriorated. As a result of persistent efforts on the part of a few paving contractors, the infrared paving process is regaining its initial acceptance. Figure 1 depicts a typical infrared asphalt heater.
