混凝土路缘石是指以水泥和集料为主要原材料，经加压、振动加压或其他成型工艺制成。铺设在路面边缘或标定路面界限的预制混凝土的界石。
Concrete curb is made of cement and aggregate as the main raw materials by pressure, vibration pressure or other molding process. The boundary stone of precast concrete laid on the edge of pavement or demarcating the boundary of pavement.
分类
classification
按功能分为：
According to the function, it can be divided into:
平缘石—顶面与路面平齐的混凝土路缘石。
Curb-a concrete curb whose top surface is flush with the pavement.
立缘石—顶面高出路面的混凝土路缘石。
Curb - a concrete curb whose top surface is higher than the road surface.
平面石—铺筑在路面与立缘石之间的混凝土平缘石。
Flat stone - a concrete flat curb placed between the pavement and the curb.
按结构形状分为直线形缘石和曲线形缘石。
According to the structural shape, it can be divided into straight edge stone and curve edge stone.
除截面形状为L型的直线形钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 缘石，按产品的抗折强度分为Cf3.0、Cf4.0、Cf5.0和Cf6.0四个强度等级；曲线形缘石和截面形状为L型的直线形缘石按产品的抗压强度分为Cc25、Cc30、Cc35和Cc40四个强度等级。
In addition to the linear curb with L-shaped cross section, it can be divided into four strength grades: cf3.0, cf4.0, cf5.0 and cf6.0 according to the flexural strength of the products; According to the compressive strength of the products, the curved edge stone and the linear edge stone with L-shape cross section can be divided into four strength grades: cc25, CC30, cc35 and cc40.
