🛣️ How a Road is Made
💫Road construction involves several stages to ensure strength, durability, and proper drainage. 🏗
1️⃣ Site Clearance
The construction area is cleared by removing trees, vegetation, and unsuitable materials.
2️⃣ Earthwork
Cutting, filling, and leveling of the ground are carried out to achieve the required road alignment and level.
3️⃣ Sub-grade Preparation
The natural soil is shaped, leveled, and compacted to form the subgrade, which is the foundation of the road.
4️⃣ Sub-base Layer
A layer of granular material (such as laterite or crushed stone) is placed and compacted to distribute loads.
5️⃣ Base Course
A stronger layer of crushed aggregate is placed to provide structural strength to the pavement.
6️⃣ Asphalt or Surface Course
Hot asphalt or concrete is laid on top to provide a smooth and durable driving surface.
7️⃣ Drainage and Finishing
Side drains, road shoulders, markings, and signage are installed to complete the road.
A road is built layer by layer, starting from the prepared soil (subgrade) up to the final asphalt surface. Each layer helps the road carry traffic loads safely. 🏗
