Research of the Luminance of Asphalt Pavements in Trafficked Areas

A key factor for safe and comfortable driving on roads are properly reflective well visible pavement surfaces at night. The brightness of the road surface depends amount light falling it reflection properties any point. luminance its physical condition, age type pavement, direction illumination, observation conditions. Different pavements can have different characteristics that depend texture, materials, binder (type quantity). Experimental research was carried out carriageways bicycle paths Vilnius city streets, which differ in color age. analysis results showed differences between reflectance these depending conditions, red asphalt better than black ones when is wet or moist. reduced coefficients carriageway (asphalt installed 2021) about 12% lower those 10 years ago 60% moist pavements. obtained from significant street designers choosing designing lighting.
