Paving roads is an essential process for ensuring the mobility and development of a region. Each stage of this process requires precision and quality so that the result is a durable, safe and efficient road.
In this article, we're going to explore the steps that go into making the bearing layer and the importance of each of them being carried out correctly.
1. Substrate preparation
The first step in paving a road is preparing the substrate, the base on which the asphalt will be laid. This process involves cleaning and leveling the surface, as well as applying a primer and bonding paint. This paint is essential to ensure adhesion between the substrate and the asphalt layer that will be applied later, preventing shifting and improving the durability of the sidewalk.
2. Application of Hot-Milled Bituminous Concrete (HMA)
Once the substrate has been prepared, the next step is to unload the Hot-Machined Bituminous Concrete (HMA) onto the paver. This machine spreads the asphalt evenly over the road surface. CBUQ is a type of asphalt widely used in paving due to its resistance and durability, making it ideal for withstanding heavy traffic.
3. Compaction
After spreading the CBUQ, the asphalt layer is compacted. This stage is crucial to ensure that the asphalt is well compressed, eliminating voids that could compromise the integrity of the paving. Compaction is carried out using a roller, which applies pressure to the asphalt, consolidating the layer and increasing its density.
4. Finishing the seams
The seams between asphalt mixes need to be treated with care to ensure the continuity and uniformity of the paving. Finishing the seams is a detailed stage that involves leveling and adjusting the edges, avoiding irregularities that could compromise the quality of the road.
5. Finishing with a tire roller
The last stage of paving is finishing with a tire roller. This equipment helps to adjust the imperfections in the asphalt layer, providing a smooth and even finish. In addition, the tire roller improves the grip of the surface, contributing to the safety of the vehicles that will be traveling on the road.
The Importance of Performing Each Step Correctly
The quality of road paving depends directly on the correct execution of each of these stages. A mistake at any stage can compromise the durability of the road, increase maintenance costs and even put drivers' safety at risk. It is therefore essential that each layer of asphalt is applied with precision, using the right materials and equipment.
