- Summary:
- Highway tunnel lighting has a key impact on traffic safety and lowcarbon energy saving. Under the same lighting conditions, the brightness and uniformity of the road surface are closely related to the reflection characteristics of the road surface. In this paper, firstly, the brightness of asphalt concrete specimens made of different materials was tested by indoor experiments, and the reflective parameters of asphalt concrete of different colors were compared, and then the images of colored pavement of different colors were collected at the tunnel site, and the brightness and uniformity indexes of the colored pavement and the conventional asphalt pavement were analyzed and compared by using graphic image analysis technology. The results show that when the lighting conditions are the same, the luminance of yellow asphalt concrete is about 2.3 times that of black asphalt concrete, and the luminance of red asphalt concrete is about 1.5 times that of black asphalt concrete, and the use of yellow or red asphalt pavement in tunnels will greatly improve traffic safety and reduce power consumption
