Asphalt Composition and Properties
The higher refractive indices for the components from Asphalt B together with the greater amount of cyclic fraction (acetone solubles at -10 F) are indicative of a higher degree of unsaturation. This unsaturation may be from aromatics or some other con figuration and for Asphalt B would be expected to produce a stronger solubillzing action

Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color. Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates that the material absorbs all solar energy and a value of 1.0 indicates total reflectance.

Refractive Index for some common Liquids, Solids and Gases
The Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as. v = c / n (1) where. v = velocity of light in the medium (m/s, ft/s) c = speed of light in air or vacuum - approximately 3 108 m/s (or 299792458 m/s) n = refractive index.
