摘要

The sustainability of our pavement systems has been recognized as an "aspirational goal", meaning that we are not quite sure if it is completely possible, we are not completely certain of the definition of sustainability, and we are still developing the means of measuring our progress towards that goal for some aspects of our different definitions. However, it is abundantly clear that we need to reduce the environmental impact of building and operating our pavement systems, that we have growing scarcity and uncertainty regarding the material and energy resources needed, and that we often have insufficient financial resources to complete that mission. The theme of this conference reflects these challenges faced by pavement engineers and managers, "Innovative and Cost-Effective Pavements for a Sustainable Future".
