- ASA – Aggregate Source Approval
In an effort to meet Standard Specification 1-06.1
“Approval of Materials Prior to Use,” WSDOT maintains the
Aggregate Source Approval system, a database list of over 7,000
aggregate sources throughout Washington that have been used for
highway construction. Access to this system is available
through the WSDOT intranet and via the internet at www.wsdot.wa.gov/biz/mats/asa/.
The ASA database is updated daily as new test results and new
sources become available.

- QPL – Qualified Products List
In an effort to meet Standard Specification 1-06.1
“Approval of Materials Prior to Use,” WSDOT maintains the
Qualified Products List system, a database list of over 1,300
construction materials that have been pre-approved for use in WSDOT
highway construction. Access to this system is available
through the WSDOT intranet and via the internet at www.wsdot.wa.gov/biz/mats/qpl/qpl.cfm.
The QPL database is updated daily as new test results and new
materials are approved.

- RAM – Request for Approval of Material
In an effort to meet Standard Specification 1-06.1
“Approval of Materials Prior to Use,” WSDOT provides the Request
for Approval of Material form (DOT 350-071). This form is to be used
by Contractors when proposed materials are not listed on the
QPL. Materials Documentation staff is available to research
and approve/reject as necessary materials proposed for use via this
method.

- ROM – Record of Materials
In an effort to meet Construction Manual 9-1.5A
“Record of Materials,” WSDOT provides a Record of Materials to
each WSDOT Project Office for every highway construction
project. This report identifies the major construction items,
listing the kinds and quantities for all materials deemed to require
quality control testing. It further identifies the minimum
number of acceptance and verification samples required for
acceptance of these materials. Materials Documentation staff
is available to research and calculate this criteria based on
contract documents, Construction Manual guidelines and the Standard
Specifications.
