Why Are Some Asphalt Red? What is Mastic Asphalt?

First in Germany in the 1960s against deformations caused by studded snow tires mastic asphalt, which was developed and first applied in Kiel, Germany, was used in the Osmangazi Bridge as well as Eurasia Tunnel and Yavuz Sultan Selim Bridge It appears in some places such as.

Before you say the bottom is asphalt What is mastic asphalt? By examining the details such as and how it differs from other species, you can acquire more information that will enlighten you.

What is mastic asphalt?

mastic asphalt; A coating material with high wear resistance, used especially on roads and bridges requiring heavy traffic. It consists of a mixture of asphalt, bitumen and fine aggregate; Mastic asphalt, on the other hand, adds a polymer additive and filler to this mixture. This additive makes the material more resistant to hot and cold weather conditions.

What are the properties of mastic asphalt?

Osmangazi Bridge construction – 2016

Red and black While mastic asphalt is available in various varieties, you can see it in red in some places such as the Osmangazi Bridge, and black is also commonly preferred. The most distinctive aspect of mastic asphalt, which stands out from normal asphalt with its technical features, is that it is in harsh climatic conditions and being the perfect option for surfaces under heavy traffic.

Its flexible structure prevents the surface from cracking and deteriorating in the face of temperature fluctuations. This feature allows mastic asphalt to be used in winter months. Resistant to icing and frost It also makes it happen. It also reduces the risk of softening and deformation at high temperatures.

In addition to its water resistance, mastic asphalt features also include long lasting There is to be. The fact that it can be used for many years thanks to its high quality and that maintenance costs are reduced thanks to this feature are among the reasons for choosing mastic asphalt.

Where is mastic asphalt used?

Mastic asphalt is used in many different areas thanks to its flexibility and durability. It is most preferred in places due to its resistance to heavy vehicle traffic. roads and parking lots. Its waterproof feature is the primary reason why it is chosen for bridges.

airports For this purpose, mastic asphalt coating material that can withstand the weight of aircraft is used. Heavy machinery and equipment industrial floors is among the areas of use of mastic asphalt.

How is mastic asphalt applied?

The application process of mastic asphalt, Although it varies depending on the characteristics of the area to be used, it generally works as follows:

• Preparation phase: The application area is cleaned and necessary corrections are made.
• Mixture preparation: Mastic asphalt mixture is prepared in specified proportions.
• APPLICATION: The prepared mixture is poured onto the application area and smoothed with multi-wheel rollers.
• Compression: The mixture is fully adhered to the surface by compression and is allowed to cool below 40 °C before the area can be opened to traffic.

What are the advantages of mastic asphalt?

In the technical specifications section, we mentioned that it is longer lasting than other surface coating materials and this Advantages of mastic asphalt a prominent factor.

smooth surface It ensures that mastic asphalt offers an aesthetic appearance. This is especially true in public areas, parks and pedestrian paths This makes mastic asphalt the ideal choice for projects where aesthetics are important, such as

Moreover stone mastic asphalt The surface texture and slip resistance of this material, also known as asphalt, is better than normal asphalt.

Does mastic asphalt have any disadvantages?

• Mastic asphalt has higher has an initial cost. This can affect budget planning, especially for large-scale projects. Additionally, its implementation may require special equipment and trained workforce, which may increase costs.
• Softening of mastic asphalt under high temperatures can cause problems, especially in areas exposed to intense sunlight. This is on the surface scarring and deformation why could it be.
• Some mastic asphalt mixtures are suitable for use in very cold weather conditions. may harden and crack.
• Correct application of mastic asphalt requires special training and It requires experience. Implementation by inexperienced teams may produce poor quality results.
• Compaction of mastic asphalt and time required to drycan extend the completion time of the project.
• Mastic asphalt contains high amounts of bitumen. Bitumen production and use can lead to environmental concerns, especially carbon footprint and air pollution about.
• Reuse of mastic asphalt and recycling, can be more complex than traditional asphalt.
• mastic asphalt, limited color and texture offers options. In some projects, more aesthetically diverse materials may be needed.

Although mastic asphalt offers significant advantages for road construction and other construction projects, it must be used according to the unique needs and conditions of each project. material selection It needs to be done.

Environmental effects of mastic asphalt

The environmental impact of mastic asphalt is an important issue as sustainability and environmentally friendly technologies become increasingly important. Mastic asphalt is reusable, It minimizes its negative effects on the environment.

Old mastic asphalt can be recycled for use in new projects. This is both reduces the amount of waste It also reduces the resource and energy consumption required for the production of new materials.
