路牙石模具国外欧洲地区使用较多，国内虽少但也有部分地区使用 路石的优点是避免车轮刮擦，减少汽车对轮胎的冲击损坏，这种型号的路石用于公交车站标志、中央绿化带等地方。 路石模具采用PP聚丙烯注塑成型，模具周转200次。
The use of toothstone mould is more in Europe abroad. Although there are few in China, some areas use the road stone. The advantages of this kind of road stone are to avoid wheel scraping and reduce the impact damage of vehicles on tires. This type of road stone is used in bus station signs, central green belt and other places. The stone mould is made of PP polypropylene injection molding, and the mold turnover is 200 times.
目前，中国上海，广州等地区已在路牙石模具使用，这个路牙石模具作风建设更节约材料可以形成去除每天一次，提高生产效率。
At present, the road stone mould has been used in Shanghai, Guangzhou and other areas of China. The construction of this type of road stone mould can save materials and form a daily removal to improve the production efficiency.
路牙石模具模国外研究欧洲国家地区以及多用途，国内虽少但也有部分农村地区可以使用。路面牙石的优点是它可以避免出现车轮刮擦，扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训减少我国汽车对轮胎的冲击造成损伤，这种影响路面微积分理论模型主要应用于城市公交系统车站、中央绿化带等场所。路面微积分模具是由pp聚丙烯注塑而成，模具可翻转200次左右。
Although there are few researches in Europe and many uses in China, some of them can be used in rural areas. The advantage of pavement calculus is that it can avoid the scratch of wheels and reduce the damage caused by the impact of cars on tires in our country. The calculus theory model of pavement is mainly used in urban public transport system stations, central green belt and other places. The road calculus mold is made of PP and polypropylene, which can be turned about 200 times.
