Abstract:
An analytical study was undertaken to account for the performance of a thin concrete overlay on an asphalt concrete (AC) pavement built in Louisville, Kentucky, in September 1991. Initial investigations and theoretical studies based on conventional concrete theory indicated that the pavement should have failed after its first few loadings. However, this did not happen. After 11 months of use, with very heavy traffic (400 to 600 garbage trucks per day, 5 1/2 days a week), the pavement has provided much better service than was anticipated, suggesting that a bond developed between the concrete overlay and underlying AC that greatly improved the pavement's performance. Some direction for future research is provided.
