What is a Road Kerb? Kerb Stone Process, Types and Application

What is a Road Kerb?

A road kerb is a raised edge or border commonly made from concrete or stone, designed to outline pavements, roadsides, medians, driveways, parking areas, and landscaping borders. Kerbs provide structural support, define road edges, enhance aesthetics, and direct water drainage.

Process of Making Kerbstone

Concrete kerbstones can be produced using three main methods:

1. Rubber/Plastic Moulding Method (Traditional Way):

Process

Wet mixed concrete is poured into rubber or plastic moulds.
Placed on a vibrating table to remove air bubbles and evenly settle the concrete.
Curing happens while concrete remains in the mould, then manually demoulded and cured further by water spraying.

Characteristics

Smooth surface finish and well-defined corners.
Limited production speed due to delayed demoulding.

2. Wet Press Method (Pressure Based)

Process

Wet concrete mixture is poured into moulds.
Water is extracted using a vacuum system, applying significant pressure without vibration.
Immediate demoulding after pressing and water extraction.

Characteristics

High-quality finish and appearance.
Higher production cost compared to other methods.
Good strength and durability.

3. Vibro Compacting Method (Vibration + Pressure Based)

Process

Dry concrete mixture is fed into a kerbstone-making machine.
The machine applies intense vibration and mechanical pressure simultaneously.
Immediate demoulding is possible after pressing.

Characteristics

High mechanical strength and durability.
Improved concrete density and reduced porosity.
Excellent surface finish and dimensional accuracy.

Types of Road Kerbs (As per IS 5758-1984)

Kerbstones are classified into four primary types based on their shapes and functional applications:

1. Rectangular Kerb

Simple rectangular shape.
Widely used for pavements and straight edging.

2. Splayed Kerb

Sloped edge designed for better vehicle tyre interaction.
Common in traffic-heavy areas, providing smoother transitions.

3. Half Batter and Full Batter Kerb

Sloped face designed to deflect vehicles onto the roadway.
Ideal for highways and areas requiring clear vehicle guidance.

4. Bull Nose Kerb

Rounded edge providing an aesthetically pleasing finish.
Suitable for landscaping and pedestrian-friendly areas.

Applications of Road Kerbs:

Defining clear boundaries for roads and footpaths.
Controlling vehicle movements and improving safety.
Managing effective drainage and surface water runoff.
Enhancing landscape aesthetics.
Protecting pedestrians by clearly demarcating pathways.
