We present results from thermal-infrared observations of binary near-Earth asteroids (NEAs). These objects, in general, have surface temperatures cooler than the average values for non-binary NEAs. We discuss how this may be evidence of higher-than-average surface thermal inertia. The comparison of these binary NEAs with all NEAs and rapidly rotating NEAs suggests a binary formation mechanism capable of altering surface properties, possibly removing regolith: an obvious candidate is the YORP effect. --- Acknowledgments This research was carried out while Marco Delbo and Kevin Walsh were Henri Poincare Fellows at the Observatoire de la Cote d'Azur.
