In this type of highway pavement, the binding material used is Portland Cement or PC. In some countries, these highways with rigid pavement construction are more popular as concrete roads. In this construction, the top layer is a concrete plate positioned above the subgrade or foundation. The nature of the main layer in the form of a concrete plate is bearing most of the load on the traffic. If there is a repetition of the load, the result will be cracks on the road surface. Meanwhile, if you’re looking for the best way to check the strength of your road, you may hire the cbr testing experts.
This rigid pavement can actually be grouped into 3 types, namely ordinary cement concrete pavement with joints without using reinforcement as crack control, ordinary cement concrete pavement with reinforcement connection as crack control, and reinforced concrete pavement types without joints.
Rigid pavement or concrete road construction is usually applied to roads with high traffic loads such as toll roads. This rigid pavement road construction has the advantage of being more durable and the cost of repairs is lower. But indeed road users feel more comfortable using paved roads compared to this concrete road.
On toll roads, the concrete used is concrete with a quality class P which has a thickness of approximately 29 cm. In this pavement process, the machine is used as a tool, namely the Wirtgen SP500 and G & Z S600 engines. Both of these machines are classified as sophisticated machines and serve to spread and compress concrete on the surface of the toll road.
The Wirtgen SP500 engine is a German-made machine that moves forward when carrying out pavement tasks. This machine is able to work on concrete as far as 1 Km in approximately 6 hours. While the G & Z S600, short for Guntert & Zimmerman, is a newer engine compared to the Wirtgen SP500 engine. The way it works is not much different, it’s just that the G & Z S600 has a longer casting range. This machine is suitable for use on roads that have a width of more than 6 meters. This machine can also adjust the thickness of the concrete to a maximum thickness of 457 mm.
