I'm working on a governmental project that uses Florida Dept of Transportation #57 stone as a landscaping material. The gravel is quarried in south Florida and is limestone rock. Does anyone know the SRI value (or range) of this material?

Thank you.

If you aren't able to find any more information, it is quite economical (and fast) to send the material for SRI testing. The Cool Roof Rating Council has a list of approved labs (https://coolroofs.org/product-rating/product-testing). Make sure you specify the correct ASTM references - LEED 2009 is different from LEEDv4. Good luck.
