Publication Details
Primary Topic: Description: The Washington State Department of Transportation (WSDOT) has achieved a dramatic improvement in the condition of its highways since it began its pavement condition survey program in the mid 1960s and pavement management system in the 1970s. The department has conducted a pavement condition survey on the entire State highway system every 2 years since 1969 and every year since 1988. In the late 1970s, WSDOT developed the first version of its Washington State Pavement Management System (WSPMS) and has been refining and using it since to manage the States pavements. The portion of pavement in good condition increased from 50 percent in 1970 to 93.5 percent in 2005.
