Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

quantification of environmental sustainability for incorporation into pavement preservation and main- tenance in the United States and Canada: 1. There is a need for pavement preservation and maintenance-specific research to furnish agency pavement maintenance engineers with the fundamental quantitative data on the rel- ative environmental sustainability of com- mon treatments. 2. There is a need to develop a pavement preser- vation and maintenance-specific life-cycle assessment and cost analysis method that includes values for factors such as carbon sequestration, resource renewability, and other salient elements of environmental sustainabil- ity to furnish a rational approach to treatment selection. 3. Research is needed to develop the fundamen- tal information needed to prepare training to be disseminated throughout the two countries that quantifies the importance of preservation and maintenance treatments in the environ- mental sustainability impact factor areas. 4. There is a need to complete research in adapt- ing recycled and alternate materials for use in pavement preservation and maintenance treatments. 5. There is a need for future research to identify and develop appropriate noise standards for pavement preservation and maintenance operations and life-cycle assessment. 6. There is a specific need for research to quan- tify the contribution that crack sealing makes to environmental sustainability of all types of pavement surfaces. 7. There is a need to research policies, tech- nology, materials, specifications, standards, equipment, capacity building, recycling/waste reduction, emissions reduction (air pollution), and life-cycle cost analysis. In this regard, it is necessary to incorporate sustainable pavement maintenance elements into on-going and future pavement maintenance research. REFERENCES Alkins, A., B. Lane, and T.
