摘要：	Pavement smoothness has been recognized as one of the measures of pavement performance. Several Long-Term Pavement Performance (LTPP) studies have addressed certain aspects of pavement smoothness, including roughness development, measurement methods, and modeling. To advance the state of practice and knowledge of pavement smoothness, a workshop on pavement smoothness was held from August 26-28, 2001, in Irvine, California as part of National Cooperative Highway Research Program (NCHRP) Project 20-51(01). Participants included individuals from state highway agencies, the Federal Highway Administration (FHWA), asphalt concrete and portland cement concrete paving industries, academia, consulting firms, and research organizations. The workshop began with a series of presentations that covered a variety of topics related to pavement smoothness. These topics included findings from LTPP data analysis studies, equipment used for measuring smoothness, findings from a FHWA survey of state practices, contractors' perspective on pavement smoothness, and state highway agencies perspective on issues related to pavement smoothness. After the presentations, workshop participants reviewed, in facilitated group discussions, the subjects of equipment and measurements, data analysis, and specifications and use. Through these discussions and a consensus-building process, workshop participants identified and prioritized nine primary issues related to pavement smoothness that require concerted efforts for advancement. Workshop participants then recommended strategies to address each of the nine issues. Workshop participants also identified groups within the private and public sectors that could play an active role in implementing these strategies. The information provided in this document should serve as a guide to those concerned with pavement smoothness in identifying, sponsoring, or pursuing parts of this extensive effort and thus help achieve the expected benefits from such measurements.
