Main characteristics of concrete road curbs BR 1000x300x150

Concrete road curbs are crucial components of urban infrastructure because they improve the resilience and aesthetics of roads while also clearly demarcating the boundaries between sidewalks and the street. The BR 1000x300x150 concrete road curb is distinguished from other types of curbs by its sturdy design and useful dimensions. This curb, which is 1000 mm long, 300 mm high, and 150 mm wide, is made to resist both environmental deterioration and the rigors of heavy traffic.

One of the main features of the BR 1000x300x150 curb is its durability. Because it is constructed of premium concrete, it is remarkably resistant to weathering and freeze-thaw cycles, which can seriously harm less durable materials. Due to its resilience, which guarantees a long lifespan and lowers the need for frequent replacements and repairs, it is an affordable option for developers and municipalities.

The BR 1000x300x150 curb’s capacity to retain structural integrity in the face of large loads is another crucial feature. This is especially important for roads used frequently by large vehicles like buses and trucks. Because of the curb’s sturdy construction, the pavement’s edges are shielded from damage such as cracking, which can result in expensive maintenance problems.

The BR 1000x300x150 curb has practical advantages, but it also contributes to road safety. It aids in driver guidance by clearly marking the boundaries of the road, particularly in places with intricate traffic patterns. This can lessen the possibility of collisions and enhance traffic flow in general. In addition, the curb can be used to divert water runoff, which helps shield road surfaces from flooding and water damage.

All things considered, the BR 1000x300x150 concrete road curb is an essential part of contemporary road building. It is a great option for a variety of applications, from crowded urban streets to more sedate residential areas, thanks to its strength, durability, and practical design. Communities can guarantee safer, more enduring, and aesthetically beautiful roads by investing in premium curbs like the BR 1000x300x150.

What are curbstones?

A 1000 mm long, 300 mm high, and 150 mm wide road concrete curb is placed alongside sidewalks and roads where heavy vehicles are expected to travel.

As a component of the urban improvement system, curbstone modification BR 100x30x15 divides road zones according to their functionality, type of coverage, and purpose.

It strengthens the boundaries of the road network in the populated areas of the regions. They need to be built to be extremely durable, frost-resistant, and strong for the intended use.

Crushed stone, sand, and gravel are added to the working mixture to give curbstones these qualities. With the use of a unique vibration pressing technique, we can create products with such precise dimensions thanks to modern construction technologies.

For placement alongside highways in urban areas, vibration-pressed curbs made of premium consumable building materials are thought to be the best option. Because of the daytime temperature variations, they are more resilient to external harm and atmospheric influences.

Regulatory framework

GOST No. 6665, released in 1991, serves as the foundational document for TU for the production of concrete road stones measuring 1000x300x150.

It makes a distinction between various grades of these curbstones to keep the intra-quarter road’s roadway apart from the sidewalks and landscaping for pedestrians:

• BR100.30.15 (1×0.3×0.15m), bevel shape — R30, concrete compressive strength — B 30, reference weight — 0.1 t;
• BR300.30.15(3×0.3×0.15m), bevel shape — R30, B 30, reference weight — 0.32 t;
• BR600.30.15 (6×0.3×0.15m), bevel shape — R30, B 30, reference weight — 0.64 t.

BR100.30.15 is composed of fine-grained concrete that has been vibrated-pressed or vibrated-cast, and it can provide the mechanical and physical properties specified by this standard.

GOST No. 23009 designates BR 100x30x15 as follows:

• first letters BR – stone designation;
• length, cm — 100;

The BR 100x30x15 production method, known as vibration casting or vibration pressing, was established by Basic GOST. The manufacturer’s capabilities and the customer’s preference dictate the first version. Conditions for storage and transportation are also specified.

They can be shipped using steel tape and wire, secured to pallets or containers. Concrete curbs that are no higher than two meters are kept on specialized 30 mm-thick wood spacers, with the bottom row resting on 80 mm-wide transverse spacers.

Purposes of using such curbs

The road curb is constructed from separate 1000x300x150 mm pieces, with a waterline—a mark indicating the potential level of precipitation—affixed to the front. They meet all GOST requirements and can guarantee easy and long-lasting operation.

Concrete curbs BR 100x30x15 are a preferred component of any city or town’s landscape design because they enable you to aesthetically and practically design roads, emphasize pedestrian zones, and more. Their great strength, large side height, and heavy weight set them apart. Heavy concrete mixtures are used in their manufacturing to ensure that they can withstand potential collisions with large vehicles on the sidewalk.

Regarding which, the following locations are the primary ones where road curbstone installation (BR 100x30x15) is permitted:

• the line of demarcation of the roadway and the sidewalk;
• reinforcement of the edge of the road surface;
• as a horizontal stop for the sidewalk. laid out of any building material.

In addition, there are areas designated for improvement and a road network, where it is not advised to install this particular type of road stone modification:

1. In car parks, parking lots and petrol stations, as they are not capable of forming an additional barrier for cars.
2. As a drainage system for sidewalks.
3. As a garden and lawn curb due to its large weight and the impossibility of laying curved sections.
4. On main roads.
5. As entrance structures to the territory.

How much does it weigh, strength and frost resistance

The manufacturing technology used to produce concrete curb stones determines its quality. The vibrating press method of using semi-dry raw materials yields the highest quality and most precise forms.

They are stronger, lighter, resistant to frost, and long-lasting. Because air bubbles are nearly entirely eliminated from the form during this pressing process, there is a much lower chance of concrete stone accidentally splitting.

The following features were established by Basic GOST for BR 100x30x15:

• strength. determined by stretching concrete in bending: Btb 3.6;
• minimum grade-M400;
• minimum frost resistance: F200;
• permissible abrasion resistance class: 0.7 g/m2;
• minimum concrete density level: B30;
• waterproofness: W6.
