The installation of a new floor is a complex process. However, using proper construction methods, common flooring can last for many years.
There is a unique step in removing and replacing pavement; these steps are crucial to the long lasting success of asphalt as explained by asphalt paving Portland Oregon.
If any procedure during the installation process is made outside of what is required by industry standard practice, this will greatly reduce the durability and life expectancy of the pavement.
For you to avoid this problem, below we list the steps of paving a track.
- Planning and Design
Excavation, earthwork and asphalt compaction are what most people think of when they hear the words steps of paving.
However, long before the first blade is lifted, countless hours are devoted to the planning and design of the asphalt. Below are some of the items that should be considered before the works are started:
- Traffic volume and location;
- Land and soil properties;
- Public service lines, drainage, and sewage;
- Climatic, environmental and residential requirements;
- Future expansion possibilities;
- Road maintenance costs.
- Preparation of Base and Sub-Base
All asphalt consists of five layers, being subgrade reinforcement, sub-base, base, regularization layer, and coating. The thickness of each layer will depend on the items evaluated in the planning stage.
However, two very important steps for pavement quality are the sub-base and the base. They provide a stable surface to support the new pavement. If the subfloor and base are not compacted properly, the surface of the asphalt at the top will not provide years of durability.
- Launching the Asphalt Mix
Once the support structures of a new pavement are installed, the fresh top layer of asphalt is added to provide clean and smooth driving.
Once ground level, an aggregate base of soil, concrete and limestone is used to stabilize the road. During this phase, channels, gutters and drains are also built.
- Joints and Transitions
It is very rare to install an asphalt surface that does not connect to existing sidewalks, roads, or parking lots. But doing it means having a say in the environment especially the place you live in.
- Final Compression
Once the asphalt and top joints have been laid, the entire surface is softened and compacted.
All these installation steps must be followed to ensure that your new asphalt surface provides years of durability and functionality.
