Preservation Strategies for Flexible Pavement Network of Washington State Department of Transportation
DR Luhr, J Li, JS Uhlmeyer… - Transportation research …, 2012 - journals.sagepub.com
The flexible pavement network of the Washington State Department of Transportation (DOT)
consists of 11,600 lane miles of asphalt pavement and 4,600 lane miles of chip seal
pavement. Every year a portion of those lane miles will require rehabilitation. However,
budget shortfalls in the past decade have created a backlog of pavement rehabilitation
needs that must be addressed. Funding forecasts for the next 10 years are for roughly one-
half the levels of those before 2000. The ability to maintain a good performance level with …

Preservation strategies for concrete pavement network of Washington State Department of Transportation
J Li, DR Luhr, JS Uhlmeyer… - Transportation research …, 2012 - journals.sagepub.com
The Washington State Department of Transportation (DOT) has about 2,400 lane miles of
mainline concrete pavements. The pavements have far exceeded their design lives and
have carried several times the estimated traffic loading. Initial Washington State DOT
estimates place the cost of reconstructing and rehabilitating the concrete pavement network
in the next 10 years at approximately $1.1 billion. However, as for most DOTs, Washington
State's roadway preservation budget has been reduced. Maintaining a good performance …
