In my project I will achieve the requirements of SSc7.2 with option 3. The roof is covert by 10% green roof and 60% white gravel and ….. My question is if I don’t get the SRI value from the manufacture of the gravel can I use the value of 79 from the LEED reference guide for calculation?

The SRI can vary a lot depending on, what exactly your gravel looks like and is made of. You will need the actual SRI either per manufacturer's data or testing. See also George's question below.
