Kerbs are precast concrete blocks or bricks, which are built between the roadway and the sidewalk and are basically flush with the sidewalk.
Kerbstone is a marker stone between pavement and other structures.
2. Different roles
The role of kerbs is to protect the safety of pedestrians and form a drainage ditch at the edge of the roadway.
Kerbs are usually needed between urban road isolation belt and pavement and between sidewalk and pavement. Curbs usually need to be located at the edge of the median, the right edge of the driveway or the outer edge of the shoulder.
3. Different characteristics
The upper layer of kerb is made of ordinary concrete, and its impermeability can prevent rainwater from flowing back into the pavement structure, and at the same time make the surface layer have strong structural strength; The lower layer is made of porous concrete to form a permeable layer, through which the water in the pavement structure can be discharged smoothly.
Curbs are suitable for block roads, and flat curbs are suitable for the whole road. They are placed on both sides of the road surface, so that the road surface and the shoulder play a connecting role on the facade, and can protect the road surface and facilitate drainage.
