A Kerbstone is a constricted stone or a concrete solid which fix end to end with other solids to form a Kerb. It makes the drivers conscious of the pavements and greenery areas in demarcating roads, streets, car parks etc. It makes a clear-cut view of the carriageway. Kerbstone helps in preventing any kind of spreading from the carriageway. Other than roads kerbstone had shown its excellence in creating lawn boundaries in houses and parks, edges along pavements, squares, car parks. With tractable technology and the flying aspect components and materials, kerbstones ride era resistance to all weather conditions, mechanical loads and also against the chemicals used in road cleaning. Kerbstone helps in making a road utmost twice, correlated with a road without them.Kerbstone helps in retaining the structural integrity of roads, Kerbstone in Saudi Arabia follows this similar technique. Kerbstone is also known for creating a barrier between vehicles and pedestrians, Kerbstone in Rwanda is a good example of such roads.
Heterogeneous types Kerbstone that you can look for:
1. Mountable Kerbs
They are also known as low Kerbs. These Kerbs promises the traffic to remain in the traffic lanes and also avow the driver to be in the restricted area with little difficulty. This Kerb allows the vehicle to climb easily because of its height of about 10 cm above the pavement edge. These are mainly laid at medians and channelization schemes, it also helps in longitudinal drainage.
2. Semi-Barrier type Kerbs
Semi-barrier Kerbs are mainly laid where the pedestrian traffic is high. They have a height of about 15 cm above the pavement edge. These Kerbs prevent trespass of parking vehicles. But with slight difficulty, it is possible to drive on these Kerbs for any quick-witted emergency.
3. Barrier-type Kerbs
Roads in foreign countries are far far better than ours. One of the reasons behind it is the construction method of their road. Barrier-type Kerbs will alarm vehicles from leaving the pavement. The pavement in Qatar is also following the similar technique. These are used in areas having less pedestrian traffic. Along with a steep batter they are placed at a height of 20 cm above the pavement edge.
4. Submerged Kerbs
Submerge Kerbs are mostly preferred in rural roads. They are used in rural roads. Generally, these Kerbs are provided at pavement edges. Lateral confinement and stability to the pavement are its promising feature.
5. Extruded Kerbs
6. Natural stone Kerb
It is not an easy task for repairing roads periodically. The only solution for this is to ensure your road with a better base. Especially highways are facing lots of problems in terms of the road. In that case usage of natural stone Kerb is the effective option even though it is costly.
7. Pre-cast concrete Kerb
These are the pet in this Kerbing category because they are strong, reliable and comparatively cheap among Kerbs.
8. Quadrants and angles Kerb
These are furnished to compliment straight and radius Kerbs. They are of different sizes and angles. Quadrant blocks can be cut to produce angles of less than 90°.
Other than this, there are also Kerbs used to enhance the visibility of a road. In the areas where visibility is restricted due to fog or extended rains, a high visibility Kerbing type is suggested. White marking or white cementing can be used for this purpose. Retro-reflective markings are also used by reflective Kerbs to improve the visibility of the road. This makes its use on lane edges at night and island Kerbs at intersections with a degree of night-time crashes.
A few special type Kerbs
- Lightweight precast concrete Kerbs
- High containment Kerbs
- Bus stop Kerbs
- Kerb-drain systems
- Aesthetic Kerbs
- Block Paving Kerbs
In short, kerbstones provides clear physical and visual marking and delineation. It helps a biker an ease drive. Kerbs are also available in different textures, colors, and standards. Natural Kerbstones are very hard, strong and long-lasting. Some stone Kerbs like Dura Kerb are lightweight and environment-friendly. It also possesses less maintenance cost.
