Soybeans Turned into Bioasphalt to Aid Farmers and Pave Roads

Innovative Solution for Soybean Farmers

• 🇺🇸 The US-China trade war has led to a significant drop in soybean exports, leaving American farmers with unsold products.
• 💡 Researchers at Iowa State University are developing a novel solution by transforming soybeans into bioasphalt.

Accidental Discovery and Development

• 🧪 The breakthrough occurred accidentally when a freshman student added too much oxygen to a soybean oil mixture, creating a sticky substance similar to asphalt.
• 🤝 This innovation was patented and is being explored for strengthening American roads.

Bioasphalt Applications and Benefits

• 🛣️ The bioasphalt can be combined with recycled gravel to create an asphalt substitute, potentially adding 20 to 30 years of life to repaved roads.
• ✨ It can also be sprayed onto existing pavement to rejuvenate roads, extending their shelf life by five to seven more years.
• 💰 This approach promises significant savings in construction, labor, and other economic costs.

Scalability and Future Outlook

• 🏭 The accidental discovery is being scaled up at manufacturing facilities nationwide, with plans to purchase 84 million acres of soybeans for production.
• ✅ The National Center for Asphalt Technologies is working to get the bioasphalt approved by over a dozen Departments of Transportation across the country.
• 📈 This technology is seen as a way to support the struggling agriculture sector while also advancing infrastructure development.
