Curbs may seem like simple concrete barriers that line streets and parking lots, but they have various classifications and types to serve different purposes. Understanding each type of curb can help you recognize its function, determine which one suits your needs, and avoid costly mistakes such as damaging your vehicle or violating traffic regulations.
Curbs are raised structures made of concrete, stone, or other materials that separate the road from sidewalks or other surfaces. They can serve a variety of purposes, including:
There are five main types of curbs:
Mountable curbs have a low height and a gradual slope, making them easy to drive over and park against. They are commonly found in residential areas, parking lots, and driveways. Mountable curbs allow for easy access for vehicles, wheelchairs, and strollers, and can also serve as a buffer between parked cars and pedestrians.
Barrier curbs have a vertical face that prevents vehicles from driving over them. They serve as safety barriers in areas such as highways, bridges, and drop-offs. Barrier curbs can also prevent vehicles from parking illegally or encroaching on pedestrian areas.
Submerged curbs are similar to mountable curbs, but they are set slightly lower, just below street level. They are commonly used to separate pedestrian areas from the street and manage stormwater runoff. Submerged curbs have a gentler slope than barrier curbs, making them more accessible to pedestrians and cyclists, and less likely to cause damage to vehicles.
Extruded curbs are similar to barrier curbs, but they have a wide base that extends into the pavement. This type of curb is commonly used in areas with heavy pedestrian traffic, such as downtown areas and shopping districts. Extruded curbs can also function as a deterrent to vehicles, preventing them from driving onto sidewalks or engaging in prohibited activities.
Monolithic curbs consist of a single piece of concrete and are typically used in areas with low-speed traffic, such as residential streets and parking lots. They are designed to withstand impacts from vehicles and can also serve as a visual indicator of parking areas.
Understanding the different types of curbs is essential for anyone who uses the roads, whether as a pedestrian or driver. Knowing what each type of curb is used for, and its limitations can help you stay safe, avoid traffic violations, and choose the right type of curb for your specific needs.
