路沿石，又稱道牙石、路邊石，是指用于劃分道路范圍、保護路面及其設施的條狀石材或混凝土制品。路緣石則是指沿道路邊緣設置的，用于保護道路路面、排水系統和綠化帶的混凝土或石材制品。從定義上看，路沿石主要起到劃分道路范圍的作用，而路緣石則側重于保護道路及其附屬設施。

Roadside stones, also known as curbstones or curbstones, refer to strip shaped stone or concrete products used to delineate road boundaries, protect road surfaces and their facilities. Kerbs refer to concrete or stone products set along the edges of roads to protect road surfaces, drainage systems, and green belts. From a definition perspective, curbstones mainly serve to divide the road range, while curbstones focus on protecting the road and its ancillary facilities.

其次，在功能方面，路沿石和路緣石有所不同。路沿石的主要功能是界定道路邊界，防止車輛和行人隨意出入，維護道路交通秩序。同時，路沿石還能保護路面，防止水分、鹽分和其他有害物質侵蝕路面，延長道路使用壽命。此外，路沿石還能起到美化和裝飾作用，提升城市道路的品質。

Secondly, in terms of functionality, curbstones and curbstones are different. The main function of curbstones is to define road boundaries, prevent vehicles and pedestrians from entering and exiting at will, and maintain road traffic order. At the same time, curbstones can also protect the road surface, prevent moisture, salt, and other harmful substances from eroding the road surface, and extend the service life of the road. In addition, curbstones can also serve as beautification and decoration, enhancing the quality of urban roads.

相較之下，路緣石的功能更注重于保護道路及其附屬設施。它能夠防止車輛和行人靠近道路邊緣，避免對道路邊緣的破壞。同時，路緣石還能起到排水作用，通過引導水流，防止雨水積壓在道路邊緣，降低道路損壞的風險。在一些綠化帶上，路緣石還能為植物生長提供支撐，保證綠化效果。

In contrast, the function of curbstones is more focused on protecting the road and its ancillary facilities. It can prevent vehicles and pedestrians from approaching the edge of the road, avoiding damage to the edge of the road. At the same time, curbstones can also serve as drainage, guiding water flow to prevent rainwater from accumulating at the edges of the road and reducing the risk of road damage. On some green belts, curbstones can also provide support for plant growth, ensuring the greening effect.

在材質方面，路沿石和路緣石有很大差別。路沿石通常采用各種石材或混凝土制成，具有良好的耐磨、耐候性能。常見的路沿石材質有花崗巖、大理石、砂巖等。而路緣石一般采用混凝土、水泥、陶瓷等材料制成，具有較高的強度和穩定性。近年來，隨著環保理念的推廣，再生混凝土、再生陶瓷等綠色建材也逐漸應用于路緣石的生產。

In terms of material, there is a significant difference between curbstones and curbstones. Roadside stones are usually made of various stones or concrete, which have good wear resistance and weather resistance. Common materials for curbstones include granite, marble, sandstone, etc. And curbstones are generally made of materials such as concrete, cement, ceramics, etc., which have high strength and stability. In recent years, with the promotion of environmental protection concepts, green building materials such as recycled concrete and recycled ceramics have gradually been applied in the production of curbstones.

再次，路沿石和路緣石在作用上也有所區別。路沿石主要是為了界定道路邊界，保證道路交通的有序進行。它在道路建設中起到關鍵作用，是不可替代的組成部分。而路緣石的作用則更多體現在保護道路及其附屬設施、排水、綠化等方面。在一定程度上，路緣石可以看作是路沿石的延伸和補充。

Once again, there are differences in the functions of curbstones and curbstones. The roadside stones are mainly used to define the boundaries of the road and ensure the orderly progress of road traffic. It plays a crucial role in road construction and is an irreplaceable component. The role of curbstones is more reflected in protecting roads and their ancillary facilities, drainage, greening, and other aspects. To a certain extent, curbstones can be seen as extensions and supplements to curbstones.

所以，路沿石和路緣石在概念、功能、材質和作用上都有明顯的區別。雖然它們都是為了維護道路安全和保護道路設施，但側重點和應用場景有所不同

So, there are significant differences in concept, function, material, and function between curbstones and curbstones. Although they are all aimed at maintaining road safety and protecting road facilities, their focus and application scenarios are different
