Differences in Road Construction Explain UK Melting Roads and Indian Heat Resilience
UK roads are melting during a heatwave with temperatures near 40°C, while Indian roads remain intact even above 45°C. This difference stems from regional engineering tailored to climate: UK roads use softer bitumen and finer aggregates to withstand freezing winters, making them vulnerable to heat. Indian roads employ harder VG-grade bitumen and larger aggregates designed to endure high temperatures and heavy traffic, preventing softening during extreme heat.
