The objective of the proposed pooled-fund project is to establish a research consortium focused on enhancing pavement sustainability. The six-year program will be developed in cooperation with the consortium participants, and will include, at a minimum, answering the following research questions: (1) What emerging materials, construction practices and pavement systems have the most potential for increasing the sustainability of our road infrastructure? The consortium will review emerging sustainable materials, technologies, products, and pavement systems, how to facilitate their adoption; and what testing, approaches, and methods are needed to adopt these technological improvements; (2) What do we need to measure --and how-- to address sustainability in the context of pavement engineering? To start answering this question, it will necessary to identify an appropriate set of metrics that cover all aspects of pavement sustainability and the adaption or development of tools for the assessment of pavement sustainability on a qualitative and quantitative relative scale; (3) How do we integrate sustainability consideration into the pavement management processes? This can be answered by looking at how sustainability considerations will affect all aspect of pavement engineering such as planning, design, construction, maintenance, management, and reclamation; (4) What changes are needed in our pavement engineering practices to adapt to climate changes? The consortium will investigate the effect of climatic change on pavement engineering in the region, in terms of design, construction, maintenance and management. |
