Curb and Gutter Systems: Types, Construction, and Pros & Cons

Introduction of Curb and Gutter

There are various types of Curbs and gutters are used in the construction of light and heavy pavements of the road. The Curb and Gutter are installed along the length of the road. The main purpose of providing a curb and gutter is to strengthen the pavement of the road.

Curb and Gutter are the structures that are made from concrete or asphalt which is used to collect the surface runoff water from parking lots or impervious surfaces.

In this article, you will get to know about the Types of Curb and Gutter and the difference between Curb and Gutter, and their Advantages and Disadvantages.

What Are Curb and Gutter?

Curb and gutters are concrete or asphalt structures used to collect surface runoff from paved streets, parking lots, or other impervious surfaces and convey it to a storm drain system or appropriate treatment and/or infiltration system. Wherever possible, eliminate or minimize curb and gutter systems.

Types of Curb and Gutter

The Curbs and Gutter can be constructed in various shapes and sizes. The curbs are generally classified according to their shape and sizes. The various types of sizes are as follows.

1. Barrier Curb and Gutter

The Barrier Curb and Gutter is one of the commonly used in sidewalks and parking spaces. Its name itself suggests that this is a curb that is constructed to form a barrier in order to separate vehicles and sidewalks or parking lots.

Barrier curbs and gutter are generally made up of cement concrete and asphalt aggregates.

2. Mower Curb and Gutter

Mower curbs are generally used in the gardens and the areas where lawns for flowering are done. This type of curbs and gutter have a decorative look which provides a strong and protective barrier between the walkway and the green zone.

These types of curbs come with various types of colours and designs and serve as a decorative function.

3. Mountable Curb and Gutter

Mountable curbs are the type of curb that has a slight dip on one face of the curb. These types of curbs allow the vehicle to drive easily from the road surface.

4. Slanted Curb and Gutter

Slanted curbs are usually ornamental curbs and which is generally installed to attract more attention to the structure. Slanted curbs do not have any practical purpose they are only used to enhance Beauty. They are mostly used for decorative purposes.

5. Monolithic Curb and Gutter

Monolithic curbs are also known as Integral curbs which are designed in such a way that is the joints between the curbs cast onto a concrete slab. The Monolithic curb is connected with the roadway.

Monolithic curbs are the type of curbs that are constructed with the road and the top level of this type of curbs are matched to create more traction. This will make it simple and easy for the vehicles to pass without any damage to the internal structure of the foundation of concrete.

The Monolithic Curbs develop a smooth transition into the road as compared to the other types of curbs.

Curb and Gutter Specifications

Standard dimensions of the Curb and Gutters are as follows.

1. Vertical Curves Used in Residential Zones

The Vertical curbs which are used in the Residential zones are as follows.

2. Rolled Curves Used in Residential Zones

The Rolled curbs which are used in the Residential zones are as follows.

Construction Process of Curb and Gutter

The construction process of curb and gutter are as follows

1. Marking and Excavation

The initial stage before starting any kind of construction is the marking of the foundation of the structure. The area or the path on which the curb and gutter have to be installed should be marked with the help of powder.

The proper gradient is given so that the water should be efficiently drained off. The area which is marked should be excavated. The excavated soil should be stacked away from the site and all the loose soil and dirt should be removed. The concrete mix should be laid and compacted properly.

2. Formwork

It is necessary that form should be used in the concreting because it helps cast curbs properly. The design of the formwork mainly depends upon the type of curb which is constructed. The formwork should be installed properly in the alignment and the label should be check with the Plumb.

3. Concreting

The concrete of the required design mix should be prepared and placed in the formwork. The concrete should be compacted properly and care should be taken that there should not be any voids remain in it.

After the concrete has set and hardened, remove the formwork and scooter on the curb and gutter surfaces. The surface of the curb and gutter should be finished properly with the help of concrete finishing tools.

4. Curing

After the concerning curb and gutter and finishing are done, then the curing of the curb should be done to achieve the desired strength and durability. It is necessary that the curb should be prevented from the traffic and extreme hot or cold temperatures.

Advantages of Curb & Gutter

There are various advantages of curb and gutter which are as follows

1. The curbs improve the Efficiency of the road sweepers why centering the debris.
2. Curbs enhance the Beauty of the parking lots and streets.
3. Curbs are also acts as back support to the pavement of the roads.
4. Gutters help in the effective drainage of water which slides down from the surface of the pavement.
5. concrete curbs have a reflective surface which helps to improve visibility at night and avoid accidents.
6. Curbs form a closed boundary which will help to improve the compaction of the concrete during the construction of the road and helps to maintain the integrity of edges.

Disadvantages of Curb & Gutter

There are also some disadvantages of constructing curb and gutter which are as follows

1. The construction of the Curb and gutters required skilled workmanship.
2. There are chances that the gets choke up in the Monsoon which may lead to water accumulation on the road surface.
