Paving Roads and Highways

Elizabeth Krajnik

Roads and highways connect small towns, major cities, and even entire countries to each other. In early history, roads used to be paths made by animals and then were adapted to suit human needs. Today, our roads and highways are paved with asphalt and concrete, among other building materials such as gravel and sand. Creating roads and highways requires swaths of land to be cleared and leveled, and may even require sections of mountains to be taken out. This book explores how these human activities have impacted Earth’s landscape and what we might be able change to create less-invasive paving practices in the future.
