路缘石是设在路面边缘的界石，也称为道牙或缘石。它在路面上还区分车行道、人行道、绿地、隔离带和道路其他部分的界线，起到保障行人，车辆交通安全和保证路面边缘齐整的作用，同时起到利于排除路面水的作用。

Kerb is a boundary stone located at the edge of a road surface, also known as a curb or curb. It also distinguishes the boundaries of roadways, sidewalks, green spaces, isolation strips, and other parts of the road on the road surface, playing a role in ensuring pedestrian and vehicle traffic safety and ensuring the smoothness of road edges, while also facilitating the drainage of road water.

路缘石主要有:立缘石(侧石)，平缘石(平石)、专用路缘石(包括弯道路缘石、隔离带路缘石、反光路缘石、减速路缘石)等。

The main types of curbs are: vertical curbs (side stones), flat curbs (flat stones), specialized curbs (including curved curbs, isolation strip curbs, reflective curbs, deceleration curbs), etc.

路缘石宜用石材或混凝土制作。在城市道路中，侧平石通常设置在沥青类路面边缘，平石铺在沥青路面与侧石之间形成街沟，也有用L道牙(侧石与平石连体)，适宜用于主车道两侧；

Kerbs should be made of stone or concrete. In urban roads, side stones are usually set at the edge of asphalt pavement, and they are laid between the asphalt pavement and the side stones to form a street ditch. They also have L-shaped teeth (connecting the side stones and the side stones), which are suitable for use on both sides of the main lane;

侧石支护其外侧人行道或其他组成部分(绿化带)，一般高出路面15～18cm。水泥混凝土路面边缘通常仅设置侧石，同样可起到街沟作用。反光路缘石(贴反光材料)，能提高道路夜间能见度，有助于行车安全。

The lateral stone support is generally 15-18cm higher than the road surface for its outer sidewalks or other components (green belts). The edges of cement concrete pavement are usually only equipped with side stones, which can also serve as street ditches. Reflective curbstones (pasted with reflective materials) can improve nighttime visibility on roads and contribute to driving safety.

.路缘石应稳固，线形平直，曲线圆顺，缝宽均匀，表面洁净不被污染，勾缝严密，不得阻水。

The curbstone should be stable, with a straight and straight line, a smooth curve, uniform joint width, a clean surface without contamination, tight joints, and no water obstruction.
