Using technology

摘要

Using technology to avoid potholes is clever, but it doesn't obviate the need to fix or prevent them. Here are a few notable efforts to achieve that: 1. Fuel spills can dissolve the 'glue' (often asphalt) that binds pieces of paving materials, like stone or gravel, together. This leaves stones exposed and wheels begin to break apart the surface, causing potholes. At the DuPont Global Paving Center in Prague, scientists receive samples of asphalt from around the world and blend in polymers to help roads resist degradation by fuel.
