Aggregate Source Approval (ASA)

The Aggregate Source Approval database stores detailed information about companies
that provide aggregate for road projects. You may search the database for the source or sources that meet your selection criteria. From the resulting list, choose which one you want to examine in greater detail. 

The ASA-GIS (Aggregate Source Approval) (Geographic Information System) map was designed to manage and track aggregate sources within the state of Washington. Sources can be located on the map using either the query tab or by manually searching, using latitude and longitude. Once a source is located and selected, a link can be followed to that source’s on-line Aggregate Source Approval report. For detailed information on how to use the GIS map, click on the map’s information tab. This will provide instruction for all of the map’s features, including Navigation Tools, Coordinate Locator, Layer Controls, Attribute Table Display, and Information Tools.

To initiate the submittal process, contact the ASA Engineer at 360-709-5442.  Electronic payment can be made through the Materials Evaluation Program (MEP).
