有一种专门在混凝土路面砖(板)或路缘石表面使用的永久性反光标识材料,也可应用于现浇混凝土或沥青路面。本文介绍近年来该项工艺技术发展和应用案例。文章所描述的材料是一种具有反射光线功能的涂料,具有发光持久和环保的特征,在混凝土路面砖(板)生产过程中涂抹在面层,就能够提供路面永久性反光标识。本文介绍的反光材料使用简单、维护保养少,特别是不管在夜晚或何种恶劣的天气条件下,都能够保持持久、清晰。该反光混合物经广泛测试表明,能够满足当前所有的应用要求。该反光混合物内含有水泥成分,具有粘合性能,可以保证牢固地粘附在混凝土或沥青路面上;它包含有玻璃微珠和其他添加剂,使其平均亮度系数达到60。在受到同等高强度交通运输压力的条件下,该反光混合物的使用年限较热塑性材料长,平均是热塑性材料的四倍,同时具有较好的防滑阻力。
There is a permanent reflective marking material that is used exclusively on the surface of concrete pavers or curbs and can also be applied to cast-in-place concrete or asphalt pavements. This article describes the process technology development and application cases in recent years. The material described in this article is a reflective coating that is durable, environmentally friendly, and provides a permanent reflective sign of the pavement when applied to the surface during the production of concrete pavers. This article describes the reflective material is simple to use, less maintenance, especially in the night or in what adverse weather conditions, can maintain long-lasting, clear. Extensive testing of the reflective compound has shown that it meets all current application requirements. The reflective mixture, which contains cementitious ingredients and has adhesive properties, ensures firm adhesion to concrete or asphalt pavement; it contains glass beads and other additives to achieve an average brightness factor of 60. Under the conditions of the same high-intensity traffic pressure, the reflective compound has a longer service life than the thermoplastic material, averaging four times that of the thermoplastic material, and has good slip resistance.
