| 摘要： | The time taken for concrete in reinstatements to cure and reach a suitable strength to allow trafficking and/or overlaying could be reduced as a measure to reduce congestion. General practice for reinstatement works is for concrete to be left for at least 3 days before being overlaid and opened to traffic. The programme investigating 3 strengths of concrete overlaid with 100 mm of asphalt and trafficked, using the TRL pavement test facility, 1 day, 2 days and 3 days after construction of the concrete. Cubes were taken to monitor the progression of strength gain over the first 28 days. Cores were taken from trafficked and control areas of the pavement and tested for compressive strength and compared with cubes. |
