Problems solved by technology

[0003] Although there are many researches and achievements on self-illuminating pavement materials, the application of these technologies has limitations:
[0005] Because stone aggregates must be mixed in, the scope of application of these materials is limited, so that the corresponding technology can only be applied to new road pavements or pavements without elevation restrictions. For pavements that have been built and have elevation restrictions, these technologies cannot be used
[0006] (2), the self-illumination effect is limited
[0007] The time span of continuous self-illumination after light storage is between 1h-8h, which cannot meet the needs of areas with poor ambient light conditions and long time spans at night
