| 摘要： | In the early 1980s the Washington State Department of Transportation (WSDOT) developed and implemented a pavement management system (PMS). Over the years, the PMS has evolved into a very useful documentation of the state highway system and an essential analysis tool for pavement design. The various elements of the Washington State Pavement Management System (WSPMS) are discussed, as are the ways in which the WSPMS is used for the rehabilitation budgeting. Early in the development of the WSPMS, the system had a strong capability to identify the specific projects that required rehabilitation and when the rehabilitation was required. The weakness in the WSPMS was determining the required level of rehabilitation (overlay thickness). The process (referred to as scoping) currently used to estimate the overlay thickness using only the data in the WSPMS is also be discussed. |
