Frequently disregarded, road curbs are an essential part of our daily infrastructure. They improve safety and aesthetics by creating the necessary division between sidewalks and streets. In order to ensure that road curbs meet the necessary standards and fulfill their intended purpose, it can be helpful to plan and construct them with an understanding of their sizes.
Three measurements are important to consider when talking about road curb dimensions: width, height, and length. These measurements change based on the kind of road and the local requirements. For instance, a curb in an industrial or commercial area might be very different from one in a residential neighborhood.
The width of the curb generally refers to its horizontal measurement on the road, which determines how much space it occupies. Contrarily, height describes the vertical distance between the curb’s base and top, which affects how the curb channels water and keeps people safe. The curb’s length determines its placement within the overall road design. It is the horizontal extent of the curb along the street.
We can better appreciate the consideration and planning that go into building our roads if we are aware of these dimensions. Be it a contractor, a city planner, or just an infrastructure enthusiast, being aware of road curb sizes is a first step toward comprehending the minute details that keep our roads secure and operational.
| Width | The width of road curbs typically ranges from 100 to 150 millimeters, providing a solid boundary between the road and sidewalk. |
| Height | Heights usually vary from 200 to 300 millimeters, ensuring the curb is visible and effective at guiding water runoff and delineating road edges. |
| Length | Lengths are commonly around 1000 millimeters, making them manageable for transportation and installation while providing stability and continuity. |

What are the values of curb barriers?
As per the regulations, road curbs are composed of concrete (GOST 6665-91) and granite (GOST 32018-2012). Based on these guidelines, producers create goods with the following measurements:
- Concrete flanging:
- BR 1000 . 300 . 150 – 1.0 x 0.3 x 0.15 m, height above the hard surface of the highway – 0.15 m.
- BR 3000 . 300 . 150 – 3.0 x 0.3 x 0.15 mm, h above the road surface – 0.15.
- BR 6000 . 300 . 150-A-IV – 6.0 x 0.3 x 0.15 m, reinforced with rod reinforcement, h above the exploited highway pavement – 0.15.
- BR 1000 . 300 . 180 – 1.0 x 0.3 x 0.18 m, h of the front face – 0.15.
- BR 3000 . 300 . 180 – 3.0 x 0.3 x 0.18 m, h of the front face – 0.15.
- BR 3000 . 600 . 200 – 3.0 x 0.6 x 0.20 m, h of the front face – 0.30.
- BR 6000 . 600 . 200-A-IV (A-V) – 6.0 x 0.60 x 0.20 m, reinforced with rod reinforcement, h front face – 0.30 m.
- BU 3000 . 300 . 290 – 3.0 x 0.30 x 0.29 mm, h front face – 0.15.
- Granite curb stones:
- GP1 – 0.50 – 2.0 x 0.30 x 0.15 m, h front face – 0.15.
- GP2 – 0.50 – 2.0 x 0.40 x 0.18 m, h front face – 0.20.
- GP3 – 0.50 – 2.0 x 0.60 x 0.20 m, h front face – 0.thirty.
Every concrete curb has a 30 x 150 mm beveled angle, or chamfer, on the side of the front edge. This chamfer’s size controls the height of the visible portion of the edging structure. Granite side edges are additionally furnished with a 30 or 40 mm radius or corner chamfer.
Most factories create their own technical specifications based on these standards, which serve as a guide for producing their products.
From every new batch, a few prototypes are chosen and put through several testing phases in order to receive a state certificate of compliance with TU, a sign of higher-quality products.
Anyone working on building or remodeling projects needs to be aware of the standard sizes for road curbs. Wider, taller, and longer road curbs are usually used to accommodate various requirements and legal requirements. This post will examine the standard measurements utilized in a range of projects and offer concise instructions to assist you in selecting the appropriate size for your unique needs. By being aware of these dimensions, you can make sure that your construction projects are installed and functionally sound, improving both safety and appearance.
Size range of curbs for different types of roads
Because different types of roadways have different limitations on height, strength, and resistance to impact loads, not all of the listed curb types can be installed to fence off any hard surface of highways or roads inside the city.
For highways
Highways are subject to the strictest regulations, which are indicated by the higher speed limit of 90 to 130 km/h. Builders use the following brands of sewing if there are any pedestrian areas on such roads, such as those near bridges, overpasses, and other structures:
- BR 1000 . 600 . 200.
- BR 3000 . 600 . 200.
- BR 6000 . 600 . 200-A-IV (A-V).
- GP3.
The need to protect pedestrians in the event of an accident involving a car traveling at a high speed led to the selection of these products.
Ordinary
Since there are rarely any pedestrians on typical suburban roads, curbs are typically not present.
Only city streets and the portions of the road where there are pedestrian zones are equipped with curbstones. The following kinds of curbstones are placed on city roads with a speed limit of no more than 60 km/h and on suburban roads with a speed limit of 90 km/h:
- BR 1000 . 300 . 150.
- BR 3000 . 300 . 150.
- BR 6000 . 300 . 150-A-IV.
- BU 3000 . 300 . 290 with an open drainage system.
- GP1.
The aforementioned curb types effectively demarcate traffic zones for automobiles, bike paths, tram tracks, and pedestrian sidewalks.
Dangerous sections
The following scenarios are indicated by the proper warning signs installed on dangerous portions of the road:
- Dangerous turn.
- Ascent or descent – with the designation of the magnitude slope.
- Uncontrolled intersection.
- Limited visibility zone.
- Uneven road surface.
The installation of reinforced curbs is necessary in these areas due to the increased risk of accidents. Typically, special flanging of the following kinds is utilized for such portions of the road:
- BR 1000 . 300 . 180.
- BR 3000 . 300 . 180.
- GP2.
Because every product made in a factory has the same weight, it is simple to determine the ground pressure and choose the ideal foundation type based on the product’s deformation characteristics and bearing capacity.
Parking
Garden curbs can be installed for parking in courtyards or shopping centers.
But as long as the vehicle parking area is part of the urban setting, road curbs must be installed with the same specifications as those around city roads.
In certain instances, builders raise curbs by shallowing them less, or the project calls for products that are higher—up to 600 mm—in order to deter parking on pedestrian zones and other traffic infractions.
Shorter elements or curbstones that are cut into 500 mm-long segments right before installation are acceptable if arranging a radius turning zone is required.
Why is it important to choose the right curbstone?
The following outcomes can be attained by choosing curbstone dimensions correctly, making it a crucial component of design, construction, and installation work:
- Increased safety of pedestrians and drivers of vehicles.
- Compliance with the requirements of SP 34.133302012 "Motorways".
- Correct ratio of the width of the pedestrian zone and its excess over the roadway.
- Reduction in the number of accidents.
- Exclusion of parking vehicles in pedestrian zones.
- Possibility of quickly calculating the weight of each product, as well as pallets for the selection of lifting mechanisms.
- The ability to calculate an estimate for the purchase of materials after taking measurements and geodetic surveying on the ground.
- It becomes possible to accurately calculate the surface area for installing the curb and determine the bearing capacity of the base.
The technical commission may reject the route into operation if the curb stone dimensions for roads of urban, regional, or federal significance are determined incorrectly. In this case, the contractor will incur additional costs to rectify the errors.
Every road that is formally registered on the village or city’s general plan is constructed in accordance with a pre-developed project, in which the engineer establishes beforehand the precise curb dimensions and creates a specification for them.
Comprehending the dimensions of road curbs is imperative for individuals engaged in building or remodeling projects. The standard dimensions of width, height, and length are crucial in guaranteeing curbs’ functionality and longevity in diverse environments. Knowing these dimensions will help you choose the ideal curb for your situation, whether it’s a quiet residential neighborhood or a busy urban street.
Standard widths, heights, and lengths for road curbs enable consistency and compatibility across various projects. For example, the standard width may be between 150 and 200 mm, and the standard height may be between 100 and 300 mm. Typically, lengths range from 900 to 1000 mm. Curbs are guaranteed to be able to endure the stresses of traffic and weather thanks to these dimensions, which are engineered to satisfy multiple engineering and safety standards.
It’s critical to take these standard sizes into account when planning your project and how they will complement your overall design. In addition to offering structural support, appropriately sized curbs also improve the area’s usability and aesthetic appeal. Understanding curb dimensions clearly will help you achieve a successful result whether you’re building new roads or remodeling old ones.
