Utilization of Bituminous Surface Treatments for Maintaining Asphalt Concrete Pavements Due to Restricted Budgetary Constraints in Washington State

The Washington State Department of Transportation (WSDOT) has had success with bituminous surface treatments (BST), also known as a seal coat or chip seal, applications for both low volume roads and as a surface treatment for asphalt concrete pavements (ACP). A BST is composed of an application of asphalt binder material (typically an asphalt emulsion) followed by an application of cover aggregate. In recent years, WSDOT, like many state highway agencies, is experiencing budgetary constraints that require maintaining the highway network with fewer available dollars. One option that WSDOT has investigated is the application of BSTs for extending the pavement life of roadways that are routinely surfaced with ACP. Certainly placing a BST over an ACP pavement is by no means unique, however, what will be explained in this paper are the processes used to obtain buy-in from both WSDOT and the hot mix asphalt paving industry, impacts to the overall pavement condition of the highway network, and the anticipated cost savings by appropriately applying BSTs to ACP pavements.
