Why is Asphalt Thickness Important?

Asphalt roads have become an indispensable part of modern life. The thickness of the asphalt used in both urban and rural areas is a critical factor for the durability and longevity of the road. So, how thick should the asphalt be? Here’s everything you need to know about this topic!

Asphalt Thickness: Standards and Recommendations

Asphalt thickness can vary depending on various factors. However, there are some generally accepted standards. Type of road, traffic density, and infrastructure conditions are among the primary factors.

Rural Roads: In rural areas, asphalt thickness of 5-7 cm is generally sufficient. On these roads with low traffic density, a thinner layer of asphalt can reduce costs.
Urban Roads: To accommodate the heavy traffic in cities, it is recommended that the asphalt thickness be between 8-12 cm. This thickness provides durability against heavy vehicles.
Industrial Areas: In industrial areas where heavy trucks and machinery are present, it is thought that the asphalt thickness should be at least 15 cm. This extends the life of the road and reduces maintenance costs.

Factors to Consider When Choosing Thickness

Some important factors to consider when selecting asphalt thickness are as follows:

Traffic Density: The average number of vehicles passing on the road daily is one of the most important factors directly affecting asphalt thickness.
Climate Conditions: In cold climates, a thicker layer may be preferred to prevent cracking of the asphalt. In hot climates, wear may occur more quickly, so attention should be paid to the thickness of the asphalt.
Infrastructure Condition: A good infrastructure is key to the longevity of the asphalt. When a thin layer of asphalt is placed on an inadequate base, the lifespan of the road will be shortened.

Advantages of Proper Asphalt Thickness

Choosing the right asphalt thickness provides many advantages in terms of both cost and safety:

Longevity: Sufficient thickness allows the asphalt to last longer, which reduces maintenance costs in the long run.
Safety: Thick asphalt helps maintain a smooth surface on the road and reduces the risk of slipping.
Cost-effectiveness: Asphalt made with the correct thickness prevents future wear and preserves the budget.

Conclusion

Asphalt thickness is of great importance for the durability and safety of the road. Thickness options ranging from 5 cm to 15 cm vary according to the purpose of road use and environmental factors. Choosing the right thickness means safer roads and long-term cost savings. This detail, which should be considered in road construction, requires a professional approach. Remember, the better a road is built, the longer it lasts!
