Abstract
A METHOD FOR DETERMINING INCIPIENT ICE LAYER FORMATION ON PAVED SURFACES IS TO BE DEMONSTRATED. THE PROPOSED TECHNIQUE WILL RELY UPON THE ENHANCEMENT IN SPECULAR REFLECTANCE, I.E., "GLARE," THAT WILL OCCUR WHEN AN OVERLYING ICE LAYER FORMS ON A PAVED SURFACE. THE PROPOSED INVESTIGATIONS WILL ALSO EXPLORE HOW OVERLYING ICE LAYERS MODIFY THE BACKSCATTERED RADIATION OBSERVED OFF PAVEMENT SURFACES. THE CONCEPT CONSIDERED WOULD INVOLVE THE USE OF A LOW-POWER INFRARED LASER "BEACON" TO SCAN AT GLANCING ANGLES (\ 10 TO 15 DEG) SELECTED AREAS OF THE PAVED SURFACE AND AN ARRAY OF DETECTOR RECEIVERS TO MONITOR THE REFLECTED/SCATTERED RADIATION. THE CHARACTERISTICS OF THE OBSERVED OPTICAL SIGNAL WILL BE USED TO INDICATE THE PRESENCE OF PAVEMENT ICING.
