Overlay with Fabric: This construction method involves grinding the edges of the existing pavement, and placing a layer of pavement fabric prior to applying a new surface course of 1.5" or 1.75" thickness of asphalt concrete on top of the existing pavement. Overlay with Rubberized Chip Seal: This construction method involves grinding the edges of the existing pavement, placing a 3/8" layer of asphalt-rubber binder and aggregate pre-coated with paving asphalt (called rubberized chip seal), and then placing a new surface course of 1.5" to 1.75" thick of asphalt concrete. This method is known as Stress Absorbing Membrane Interlayer (SAMI). The rubberized chip seal interlayer provides increased flexibility of the surface and increased resistance to reflective cracking. The SAMI method will be utilized on streets that were originally scheduled to be reconstructed using the "rip-off' method, or "total recycle" method, without base stabilizer. The "rip-off' or "total recycle" method of pavement restoration would require the complete removal or grinding of the existing pavement surface. By using a stress absorbing membrane interlayer, the existing pavement surface is left in place where stable base materials occur. Staff believes that SAMI will not only minimize the construction impact on local residents, but will also minimize the potential of encountering unstable sub-grade materials during construction.
