WSDOT - Geotech Data Aggregate Resource Sites

Points depict aggregate sources that have been tested by the WSDOT State Materials Laboratory and are created from data in the Aggregate Sources Approval database (ASA). The Aggregate Sources Approval database identifies aggregate sources that have been tested by WSDOT, and have been assigned a county letter code with a sequential number for that county. It should be noted that there are sources that have been tested, but not classified with a county code, and are therefore not included in the database. Also, there are sources in the database that are not currently approved for use as materials on construction projects.数据点代表经华盛顿州运输部（Washington State Department of Transportation, WSDOT）州材料实验室检测的集料源，相关数据源自集料源审批数据库（Aggregate Sources Approval Database, ASA）。该数据库会对经WSDOT检测的集料源进行标识，并为其分配对应所在县域的字母编码及该县域内的顺序编号。需要说明的是，部分已完成检测的集料源未被分配县级字母编码，因此未被纳入该数据库。此外，数据库中亦存在当前未获批可作为建筑工程材料使用的集料源。
