Road Structure Cross Section is composed of the following components: Surface/Wearing Course. Base Course. Sub Base. Sub Grade. 1. Surface/Wearing Course in pavement cross section: The top layers of pavement which is in direct contact with the wheel of the vehicle. Usually constructed of material in which bitumen is used as binder …

Lay the sub-base material over subgrade, maintaining the thickness of the layer. The maximum allowable variation for material thickness is 6mm for a 4.5 m stretch of road. Water the layer before …

The road drainage system consists of two parts: dewatering and drainage. ... If the construction is a large pipe with a clear opening of 2-4 m, the culvert is defined as a pipe bridge. The shape of a culvert is usually a round pipe, but culverts can also be pipe arch, structural arch or box. The shape depends on the site, the required area and ...

Together, these components ensure the efficient operation and maneuverability of the road roller on construction sites. Frame and axles. The frame and axles are crucial parts of a road roller, providing structural integrity, stability, and maneuverability. The frame serves as the backbone, supporting the weight of the roller …

Bridge deck. Deck: The deck (also known as the roadway or surface) of a bridge is the functional area that allows vehicles and pedestrians to cross highways, valleys, and bodies of water. ( Utility infrastructure is often hung below the deck.) Decks are usually constructed of concrete, steel, wood, or a grating system.

Fig. 1: Earthen Road. 2. Gravel Roads. Gravel roads are also low-quality roads, but they are better when compared with earthen roads. A compacted mixture of gravel and earth is used as pavement material in this case. Fig. 2: Gravel Road. 3. Murrum Roads.

Road Camber is an important element of road design and construction. It is the inward slope of the road surface from the center to the sides. It helps with drainage, grip, and safety when driving. ... It is also important to check for worn-out parts in the road camber, such as joints, bolts, or screws. These should be replaced immediately, or ...

The pavement types of road pavements are mainly classified into two basic categories: Flexible pavement road and Rigid highway pavement. Flexible pavement ; Rigid pavement; 1. Flexible Pavements. Flexible pavements, a prime example of what is pavement in road construction, are the type of road pavement that can adapt their …

3. Earthworks. Earthworks, the most labour-intensive procedure in road construction, involves the deployment of a grader on-site to remove the topsoil. The site is then scraped and graded to expose the underlying ground, known as formation level. This is the level at which excavation ceases and construction on the road starts.

1. Sub Grade: Subgrade is the foundation of the road, thus its the lowest and most important component of road structure. …

If the road surface is to be constructed at or below the original ground level, the formation will be in a cutting, where material has been removed – excavating to the required depth. Alternatively, if the road surface is above the original ground level, the formation will be the top surface of an embankment formed from imported soil.

Using the right materials when building a road is important. By choosing a solid base and a good gravel mix for the top, you can make a road that is strong and is cost-effective over time. 4. Withstand different weather conditions by compacting the soil. Close-up of a roller's wheel used to compact soil on a gravel road.
