Thank you, Mr. Chairman. There is a high degree of variability. Asphalt should be expected to last at least ten years, perhaps longer. Chip-seal, on the other hand, will not last nearly so long as asphalt, but it depends on the base and whether there has been any embankment failures. It depends on erosion on the shoulders, it depends on many, many factors. So, really, what you have in the chip-seal replacement repair project is a result of the spring inspection of the system.
Our folks go out and have a look to see where the chip-seal is breaking up or where there are grade failures, where there are problems, and they allocate the money on that basis, but normally, we would hope that the chip-seal is going to last at least six years.
