Why UK Roads Melt in 40°C Heat While Indian Roads Withstand Higher Temperatures

The vulnerability of UK roads to melting at 40°C, compared to Indian roads that endure far greater heat, is not a matter of construction quality. The key difference lies in how road materials are chosen based on the expected climate of each region. In the UK, road-building materials are engineered for a temperate climate, making them ill-suited for extreme heat events. India, by contrast, uses materials formulated to withstand consistently high temperatures. This climate-specific approach to material selection explains why the same temperature can cause vastly different outcomes on roads in different countries.
