There are many exciting innovations currently occurring in the pavement engineering and management field. It is apparent that these innovations in design, material selection, construction practices, maintenance procedures and management of road networks present many opportunities for the Australian Asphalt community to implement these innovations to provide technical, economic and in many cases environmental benefits. It also means there can be costs to implementing some of these innovations so these need to be managed properly and efficiently. This paper summarizes a framework on how innovative asphalt technologies can be assessed in a quantitative manner. It is based on some on-going research that is currently underway at the Queensland Pavement Centre located at the University of the Sunshine Coast and various industry partners. More specifically, it is directed at integrating laboratory and field testing in an engineered way to determine how effective various materials, designs and technologies are. The paper initially describes how a technology can be assessed in a factorial manner. It then identifies how key performance indicators can be selected and subsequently examined. This analysis is presented in a decision tree matrix. Finally guidelines are presented on how an engineered test section might be designed and constructed to ensure all the important parameters are tested while all parties are able to manage risk. The paper is directed at both public and private sector stakeholders in the industry who may be looking at testing a new material or technology. Overall, this paper shares some best practices on key aspects to quantifying costs and benefits and provides a few examples of how recent technologies have been assessed under this framework.
