Pavement albedo is an important factor when evaluating thermal performance of pavement. Many pavement thermal models have used a constant albedo value in their simulations of pavement temperature profile, but in the real world the albedo value keeps changing diurnally. Information regarding albedo value for different materials is currently limited. Pavement tining is a common practice used in interstate highways in order to control the noise and pavement expansion. There has been, however, no report studying the influence of pavement tining on pavement albedo. This study investigates three topic: diurnal variation of albedo value, influence of albedometer height and its measuring range, and influence of pavement tining on pavement albedo.
All albedo measurements used albedometer test method. Diurnal variations of albedo value were examined for both concrete and asphalt pavement. An analysis of energy collection based on both dynamic and constant albedo values was performed. The influence albedometer height on measuring range was examined for 2 different albedometer heights. The influence of pavement tining on pavement albedo was examined for two experimental parking lot sections.
