It has happened a lot that during the implementation of street asphalt, we have also seen some of the work steps, or that this operation takes place at our place of residence, and we are dissatisfied with the long time it takes to do it, and we wonder why this work takes so long. Does it take long?
Nowadays, asphalt work has become very important in road construction and the beauty of city, village, etc. surfaces. In fact, asphalt is a combination of gravel, sand and mineral or artificial bitumen and has different granularities and is divided into three categories: hot, cold and protective asphalt. Asphalt implementation instructions have different stages and it is necessary to pay attention to different points and factors at this time so that the final result is acceptable. We will examine these steps in the following.
Street asphalt implementation steps
In general, asphalts are placed in three general categories and are made of different materials such as gravel, sand, mineral bitumen and even natural bitumen. In general, for the implementation of asphalt, 4 different stages should be put on the agenda, which are:
- Asphalt infrastructure
The first and most important stage of the implementation of street asphalt is the infrastructure, which itself consists of various parts such as slope construction, bridging, tabulation, etc. At this stage, they generally use different materials and materials such as sand, gravel, etc. according to the need and completely cover the desired surface. Then, using road construction equipment such as grader, the spilled materials are smoothed.
After the street surface is well sanded, it can be sprinkled with water and the desired surface can be prepared for the next steps with a roller.
- Bituminous spraying
Bituminous spraying is known as the second stage of asphalt implementation and is very important. In fact, at this stage, all the pores between the sand and pebbles should be covered with bitumen and finally the surface of the street should be completely uniform and unified. Bituminous spraying also makes it easier to carry out the next steps and causes better adhesion of the asphalt.
- Asphalting
After the substructure and asphalting of the street surface, it is time for the main asphalting stage. The asphalting stage itself is divided into two main parts. In the first part, a bit of asphalt is spread on the prepared surface by the finisher.
This layer of asphalt, which is known as lining, is one of the most important parts of street asphalt implementation. After the lining, it is time to apply the main asphalt, which must be applied in the standard thickness.
- Asphalt rolling
After the implementation of the mentioned 3 steps, it is necessary to use special rollers, which are generally rubber, steel, etc., to compress the asphalt. Asphalt rolling also requires a lot of care and attention and should be done by skilled and skilled people.
How to implement hot asphalt
In many cases, the implementation of street asphalt is done by warm asphalt and it can be called as the most common type of asphalt. The implementation steps of this type of asphalt can be summarized in the following:
- Carrying out infrastructure and removing unevenness
sprinkling a bitumen layer on the subsurface in the second step known as the priming step; The purpose of this work is to prepare the working conditions for the final implementation of asphalt.
Pouring a thin layer of bitumen on the surface of asphalt or concrete in the third step, which is a single coat; The purpose of this work is to increase the adhesion of asphalt.
Pouring hot asphalt under a certain temperature and manually or mechanized on the prepared surface
- Rolling and compacting asphalt
Street asphalt implementation involves the process of constructing or repairing road surfaces using asphalt as the main material. Bitumen 60/70 is a commonly used grade of bitumen in asphalt mixtures for road construction. Here is an overview of street asphalt implementation and the use of bitumen 60/70:
- Asphalt Mixtures: Asphalt mixtures used in street construction are typically composed of aggregate, binder (bitumen), and additives. The aggregate provides strength and stability, while the bitumen acts as a binder to hold the aggregate particles together.
- Bitumen 60/70: Bitumen 60/70 refers to a specific grade of bitumen that is classified based on its penetration and viscosity characteristics. The numbers 60/70 indicate the penetration value (in 1/10th of a millimeter) of a standard needle into the bitumen sample at 25 degrees Celsius after 5 seconds. Bitumen 60/70 has a relatively intermediate penetration range, indicating its suitability for various asphalt applications.
- Asphalt Paving Process: The street asphalt implementation process typically involves the following steps:
- Preparation: The existing road surface is prepared by removing old asphalt, debris, and vegetation. Any necessary repairs or adjustments to the road base are made.
- Asphalt Mixing: The hot mix asphalt (HMA) is produced in asphalt plants. Aggregates of specific sizes are mixed with bitumen and additives in precise proportions to meet the required specifications.
- Hauling and Placement: The hot asphalt mixture is loaded onto trucks and transported to the construction site. It is then placed and spread using paving machines or manual methods. The asphalt is compacted using rollers to achieve the desired density and smoothness.
- Surface Finishing: After compaction, the surface may undergo additional processes such as applying a surface treatment, like a seal coat or a thin overlay, to enhance durability and skid resistance.
- Benefits of Bitumen 60/70: Bitumen 60/70 offers several advantages in street asphalt implementation:
- Good workability: Bitumen 60/70 has suitable viscosity and flow properties, making it easy to mix, transport, and apply during the paving process.
- Adequate durability: The properties of bitumen 60/70 provide a balance between stiffness and flexibility, ensuring that the asphalt pavement can withstand traffic loads, temperature variations, and other environmental factors.
- Excellent adhesion: Bitumen 60/70 exhibits strong adhesion to aggregates, promoting good cohesion within the asphalt mixture and enhancing the overall performance and lifespan of the road surface.
- Cost-effectiveness: Bitumen 60/70 is typically cost-effective compared to other bitumen grades, making it a popular choice for various road construction projects.
Overall, street asphalt implementation involves the meticulous process of preparing, mixing, placing, and compacting asphalt mixtures using suitable bitumen, such as bitumen 60/70. This helps create durable and high-quality road surfaces that can withstand the rigors of daily traffic and environmental conditions.
