Solar Reflectance Index (SRI) indicates a material\'s ability to reject solar heat and is the combined value of reflectivity and emittance. Measurements vary from 100 (standard white surface, most reflective) to 0 (standard black surface, least reflective). Materials with the highest SRI values are the coolest choices for paving.

The higher the SRI number the more solar heat the material can reflect. Black asphalt has an SRI of 0.
