S.S. Inozemtcev, H.T. Le, E.V. Korolev · Stroymaterialy · 2026
This study demonstrates the effectiveness of AR-polymer capsules in enhancing the self-healing properties of asphalt concrete.
Plain English summary
Why this matters
Key findings
- Self-healing asphalt concrete can be produced without changing the production process.
- Capsule distribution is uniform, with 22%-28% of capsules in each core sample.
- Capsules increase self-healing compressive strength to 38.8% of residual strength.
- Self-healing rate improved by 2.5 times to 11.5% of compressive strength per day.
- Voids larger than capsule diameter ensure 96% preservation of capsules.
What's new
The study demonstrates the practical application of AR-polymer capsules in asphalt concrete for self-healing, confirming their effectiveness in an industrial setting.
Limitations
The abstract does not provide details on the long-term performance or economic analysis of the modified asphalt concrete.
Commercial context
