Abstract: The discrimination of the reactive two component wearable road coating system is discussed, which is prepared with styrene, waste polystyrene foam plastic and unsaturated polyester resin. A systematic study is conducted on various factors influencing the light reflectance and retroreflecting coefficient of the road coating. The curve of the adding amount of titannium white powder, the viscosity of road coating and the retroreffecting coefficient of road coating is obtained. The specific method is given for discriminating the day and night discrimination effect of road coating.

Key words: light reflectance, retroreflecting coefficient , reactive road coating
