NOTE: The list of sources and required tests will be
taken from the concrete materials design memorandum.
**************************************************************************
Concrete aggregates may be furnished from any source capable of meeting the
quality requirements stated in paragraph AGGREGATES. The following sources
were evaluated during the design phase of the project in [_____] and were
found at that time capable of meeting the quality requirements when
suitably processed. No guarantee is given or implied that any of the
following listed sources are currently capable of producing aggregates that
