Climate change affects not only natural ecosystems but also directly influences the infrastructure sector. Rising temperatures, heavy rainfall, frost cycles, and sudden weather changes put significant strain on the performance of bitumen and asphalt pavements. For this reason, developing climate-friendly and sustainable solutions has become essential in modern cities and transportation projects.
Major Impacts of Climate Change on Bitumen and Asphalt
Extreme Temperatures
High heat causes asphalt to soften, deform, and rut.
Combined with heavy traffic during summer, the lifespan of asphalt is shortened.Freeze–Thaw Cycles
In cold regions, water on asphalt surfaces freezes and thaws, leading to cracks.
Ground movements caused by these cycles result in pavement deterioration.Heavy Rainfall and Flooding
Rainwater seeps into the lower layers of asphalt, weakening the structure.
Roads with poor drainage deteriorate rapidly.UV Radiation
Ultraviolet rays from the sun weaken the chemical structure of bitumen.
Asphalt surfaces become brittle and more prone to damage.
Climate Resilience Solutions for Asphalt and Bitumen
Polymer-Modified Bitumen (PMB):
Provides resistance against temperature fluctuations.
Reduces cracking and deformation.
Emulsion Bitumen:
Offers more eco-friendly and flexible solutions.
Climate-friendly with lower energy consumption.
Porous Asphalt:
Prevents water accumulation in rainy regions.
Creates roads more resistant to flooding.
Reclaimed Asphalt Pavement (RAP):
Provides both environmentally friendly and cost-effective solutions.
Reduces the use of natural resources.
New Technologies for Climate Adaptation
Self-Healing Asphalt: Special additives enable cracks to repair themselves.
Energy-Storing Asphalt: Captures solar heat for energy recovery.
Noise- and Heat-Reducing Pavements: Improve quality of life in urban areas.
The Situation in Turkey
Turkey’s diverse climate zones require tailored asphalt solutions:
Mediterranean and Southeastern Regions: Asphalt resistant to high temperatures.
Black Sea Region: Porous asphalt suitable for heavy rainfall.
Central and Eastern Anatolia: Polymer-modified bitumen resistant to freeze–thaw cycles.
