From which source can the specific gravity of approved Louisiana aggregates be obtained?

The specific gravity of approved Louisiana aggregates can be obtained from the Qualified Products List. This list is a vital resource provided by the Louisiana Department of Transportation and Development, which contains information on materials that have been tested and approved for use in construction projects. By referring to this list, inspectors and engineers can ensure that the aggregates they are using meet the required standards and have the appropriate physical properties, including specific gravity.

Other sources, such as project specifications and technical data sheets, may provide relevant information, but they are not the definitive sources for ensuring the aggregates meet state-approved criteria. The Aggregate Testing Lab performs testing, but the Qualified Products List is where the officially approved materials and their properties are compiled and readily available for verification.
