blue glass method reflectance factor

Test method for coefficient of retroreflected luminance of horizontal coating is a great method which can test the performance very well,along the standard established,the research on the retroreflectance of horizontal coating will get improved.

《水平涂层逆反射亮度系数测试方法》是一个真正意义上的路面水平涂层的逆反射性能的测试方法,它的颁布为国内系统完整地开展路面水平涂层的逆反射性能研究打下了基础。
