TRB's National Cooperative Highway Research Program (NCHRP) Research Report 858: Quantifying the Effects of Preservation Treatments on Pavement Performance presents a proposed framework that uses performance measures to quantify the changes in pavement performance in terms of condition, service life, and life-cycle costs. Pavement preservation provides a means for maintaining and improving the functional condition of an existing highway system and slowing deterioration. Additionally, the guide identifies alternate performance measures and describes a process for assessing their appropriateness for use in quantifying the effects of preservation treatments on pavement performance. Incorporating these measures in asset management systems would provide a means for selecting the appropriate preservation treatments and optimizing the allocation of resources.
