The Idaho Geological Survey (IGS) will examine lithologic composition of screened gravel from aggregate sources used currently by ITD
statewide and will evaluate those results in terms of potential for ASR in concrete using that aggregate.
The report will be disseminated to the public through an Idaho Geological Survey publication.
A GIS/GEODATABASE will be implemented for ITD use.
The objectives of this project are:
Identify source gravels by formational units.
Compile technical specification and develop sampling protocols.
Characterize the source material used in road construction from samples obtained throughout Idaho.
Lithologic results compiled into percents and entered into a spreadsheet.
Survey publication, such as a map showing the geologic features and characterization of the aggregates studied, made available to the public.
Implementing the data into a GIS/GEODATABASE for ITD use.
