1results about How to "Stable Luminescence" patented technology

This invention relates to the field of traffic engineering technology, specifically to a method for preparing and paving prefabricated luminescent concrete road markings. The method includes: preparing prefabricated luminescent concrete marking slabs made of white silicate cement, aggregates, long-afterglow luminescent materials, and admixtures through casting and curing; embedding the slabs into installation grooves formed in the road surface, ensuring their upper surfaces are flush with the road surface; and filling the joints with sealant. This invention employs a prefabricated assembly process, enabling industrialized production and quality control, and solving problems such as construction pollution, poor visibility in rainy and nighttime conditions, and difficult maintenance associated with traditional road markings. The slabs incorporate luminescent materials throughout, resulting in excellent nighttime visibility; the optimized mix ratio gives the slabs both superior mechanical and luminescent properties; the service life is 5-10 times that of traditional road markings; the total life-cycle cost is reduced by 30%-50%; and it is environmentally friendly. It is suitable for newly constructed asphalt pavements, newly constructed cement pavements, and the reconstruction of existing roads.
