This paper describes the major stages and component steps leading to the realization of the technical and commercial potential of a new construction technology. It encompasses a process of innovation and invention, which is generically applicable to any construction innovation. A case illustration of a new asphalt compaction technology is also described within each stage to provide a "real life" example. Motivation for the new technology came from the fact that existing, conventional rollers can cause serious damage to the compacted asphalt mat at the time of construction. This damage is in the form of construction cracks, often termed "roller checking", which can result in accelerated, in-service deterioration. The new technology originally termed the "Asphalt Multi Integrated Roller" (AMIR), overcomes the problems of current rollers through stiffness compatibility with the asphalt mix and a different geometry than conventional rollers. Commercial realization of the technology has been achieved through a new generation of AMIR, termed "HIPAC." The paper also provides background on the issues of concern to pavement engineers, including limitations of current compaction methods. It explains in functional terms the unique difference provided by the new technology. As well, it describes the major hurdles that were overcome to achieve commercial realization.
