How It's Made: Asphalt & Roofing Felt That Survive 360°F Heat and Freezing Cold!

Описание: Every year, the world produces over 100 million tons of bitumen and asphalt – enough to pave a road to the Moon and back 15 times! We'll show you how crude oil's heaviest residue transforms into materials that survive under 40-ton trucks and protect roofs for decades. You'll discover the chemical secrets manufacturers hide: why polymer modifiers prevent cracking at 360°F, how mineral granules shield against UV radiation, and what happens inside massive mixers at 1,200°F when bitumen becomes the foundation for bridges, airstrips, and warehouse roofs.
