Order of Stages of Estimation of Concrete Roads
The correct order of stages of estimation for concrete roads is option 'A': Earthwork excavations, cement concrete for the base course (1:4:8), and cement concrete for the wearing course (1:2:8). Let's break down each stage and explain why this order is correct.
1. Earthwork Excavations:
- The first stage in the estimation of concrete roads is earthwork excavations. This involves the removal of soil, rocks, and other materials from the road construction site to prepare the foundation for the road.
- Excavation is necessary to achieve the desired road elevation and to remove any unsuitable materials that may affect the stability and durability of the road.
2. Cement Concrete for the Base Course (1:4:8):
- The second stage is the construction of the base course using cement concrete with a mix ratio of 1:4:8 (cement:sand:aggregate). This mix ratio is a common standard for the base course of concrete roads.
- The base course provides a stable and strong foundation for the road. It helps distribute the load from vehicles evenly and prevents the road from sinking or cracking under heavy traffic.
3. Cement Concrete for the Wearing Course (1:2:8):
- The third and final stage is the construction of the wearing course using cement concrete with a mix ratio of 1:2:8 (cement:sand:aggregate).
- The wearing course is the top layer of the road that comes in direct contact with vehicles. It needs to be durable, skid-resistant, and able to withstand the impact and abrasion caused by traffic.
- The mix ratio of 1:2:8 provides a higher cement content, which results in a stronger and more durable wearing course.
Explanation:
The correct order of stages mentioned in option 'A' follows a logical sequence. First, the earthwork excavations are carried out to prepare the road foundation. Then, the base course is constructed using cement concrete with a mix ratio of 1:4:8. Finally, the wearing course is constructed using cement concrete with a mix ratio of 1:2:8.
This order ensures that the road is built on a stable foundation and that each layer has the required strength and durability. Starting with the earthwork excavations allows for proper site preparation, while constructing the base course before the wearing course ensures that the road has a solid base to support the top layer.
By following this order, the concrete road will have the necessary strength, stability, and longevity to withstand heavy traffic loads and environmental factors.
