Types of Asphalt and Key Differences

Asphalt emerges as a critical component in road construction. The two main types used in road building, cold asphalt and hot asphalt, come with their own advantages and disadvantages. In this article, we will take a closer look at the differences between cold asphalt and hot asphalt, and we will also explain asphalt prices and the cost of 1 km of asphalt road.

Hot Asphalt: A Warm Approach

Hot asphalt is generally a process where the asphalt mixture is processed at high temperatures of around 150-180 °C. This temperature allows the asphalt to become more flexible and fluid, thereby increasing the smoothness of the surface and resulting in a long-lasting road surface. One of the biggest advantages of hot asphalt is the excellent development of its waterproofing and durability properties. Therefore, hot asphalt is often preferred for major roads, highways, and areas with heavy traffic.

Cold Asphalt: A Practical and Economic Solution

Cold asphalt, on the other hand, is produced by processing the asphalt mixture at low temperatures (usually 20-30 °C). This allows for the quick application of cold asphalt, making it particularly preferred for emergency repair works. The application process of cold asphalt is generally faster, which saves labor and time. However, it is less durable than hot asphalt, and cracks and wear can occur over the years. It is generally used for village and neighborhood roads, and small repairs.

Asphalt Prices and Cost of 1 Km of Asphalt

Asphalt prices vary depending on the type of material used, quality, and the area to be applied. For example, the production cost of hot asphalt is higher because it is processed at high temperatures. As of 2023, the cost of 1 km of hot asphalt road in Turkey is approximately 300,000 - 500,000 TL.

The price of cold asphalt is generally lower, making the cost of 1 km of cold asphalt road around 100,000 - 200,000 TL. However, these costs can vary depending on local government budgets, the quality of the asphalt, and labor costs.

Considerations in Asphalt Selection

Traffic Density: The traffic density of the road to be used is very important when deciding which type of asphalt to use.
Climate Conditions: Cold asphalt may deteriorate more due to water effects in some regions. Therefore, climate conditions play an important role in the selection.
Cost Analysis: The cost of 1 km of asphalt is a critical factor when considering the project's budget.

Future Trends and Sustainability

Looking to the future, sustainability is becoming prominent in both cold and hot asphalt applications. The use of innovative materials and the increasing prevalence of recycled asphalt mixtures are reducing the environmental impacts of asphalt and resulting in more durable road surfaces. Additionally, the use of local materials is being encouraged to lower asphalt costs.

Conclusion

In conclusion, the differences between cold asphalt and hot asphalt are critical in road construction. It is important to consider asphalt prices and the cost of 1 km of asphalt road when making a choice that suits your needs. When the right choice is made, you can have both an economical and durable road surface.
