CONCRETE PAVEMENTS

Concretes are the best for road construction especially for pavements since they are rigid in nature and have high tensile strength. The concrete has various characteristics according to the required pavement structure and it can be modified and changed.

Also, concrete is used for several other road constructions like grade one and two highways that withstand diesel spillage and other aggressive materials other than possessed by bituminous pavements.

Types of Concrete Pavements

There are three types of concrete pavements used in the construction and they are,

· Jointed unreinforced concrete pavement

· Jointed reinforced concrete pavement

· Continuously reinforced concrete pavement

And these are explained as follows,

Jointed unreinforced concrete pavement –

They are Cost effective, reliable and so used widely for pavement construction. But they don’t possess reinforcement and has transverse joints spaced as per design. The special feature is it has dowel bars to transfer traffic loads.

Jointed reinforced concrete pavement –

They have both joints and reinforcement and are designed to withstand and hold tightly together increasing crack resistance. However, it is difficult to inspect the joint cuts where the reinforcement is discontinued. This pavement was once used in the state highways construction and it is not commonly used except by some municipalities.

Continuously reinforced concrete pavement –

These have no transverse joints but have longitudinal reinforcement thus transverse reinforcement is often used. The special feature of this pavement structure it allows development of cracks within an allowed space and also has the capacity to hold cracks tightly together.

MACHINERY

There are many cold milling machines manufactured around the globe. These types of machinery allow the construction to be simple and reliable with fully hydraulic driving design attributes. They are best for fast, efficient removal of asphalt and for constructing concrete pavements.

One of the most noticeable manufacturers of this design equipment is SCHWING STETTER.

They have the most attracting features like,

1. Flexible steering

2. Scientific layout of the operating system

3. Right leg rotating way for meeting narrow welt construction

4. Enhanced braking effect

And also other manufacturers that hit the competition are GOMACO, ALLEN ENGINEERING, and TEREX etc.
