What is a rigid sidewalk?
The rigid sidewalk is a technical term for any surface of the concrete road. Concrete roads are called strict, while roads covered with asphalt are flexible. These terms relate to the amount of deformation created on the road surface itself while using and over time. The biggest advantages of using the concrete pavement are in its durability and the ability to hold shape. There are three basic types of rigid sidewalks commonly used worldwide.
The basic rigid pavement design is very simple. The surface layer, composed of Portland cement concrete (PCC) boards, is located at the top of a handful of partial layers. The layer directly below the PCC is more flexible than concrete, but still quite stiff. This layer provides a stable base for PCC and drain assistance. Some roads have under the first, which is even more flexible, the second pad, while some simply have existing soil. The biggest factor in deciding whether this second layer is necessary is the composition of an existing friendDarial.
Flexible and stiff sidewalks are two basic styles of road surfaces. The flexible sidewalk is almost always asphalt, while the rigid sidewalk is concrete. The difference between these two styles usually comes to deformation. The flexible pavement allows significant deformation at heavy loads; This means that the road bends when it is placed under stress. The song pavement remains firm when it is placed under stress and will burst when the stress exceeds its tolerance.
The way in which the concrete pavement deals with cracking is the main difference between three styles of the pavement. The most common style, connected to ordinary concrete (JPC), consists of boards without steel reinforcement. When cracks develop, they should occur in cracks between the boards, which will facilitate the road surface.
Connected reinforced concrete contains a steel mesh that strengthens the structure of the concrete slab. COD COVERS USED IN THIS SYSTEMU are often much larger than those used in JPC designs. Strengthening prevents some cracks, allowing effective larger boards. Cracks, when they appear, still usually occur between plates.
The third style, continuously reinforced concrete, contains a high amount of steel reinforcement. These boards are not designed to crack at the connection points - the board itself. Strengthening steel holds cracks together so closely that they do not cause structural problems in the board.
There are two main reasons for using a rigid pavement that come from its hardness. Because the surface is heavier, it is also more durable over time. This keeps the road in good operating state much longer than softer surfaces. The second advantage of concrete roads is their shaping. Since the surface can withstand a lot of weight without deformation, it is possible to create groves and channels on the road to provide additional tracones to move water from the surface of the road.
