• Mill-and-overlay vs. other pavement preservation methods

    While a regular mill-and-fill program will extend pavement life just as well as a preventive maintenance program the life-cycle cost between the two approaches is dramatically different. Using recent local pricing and discounting future activity costs to present value with a 4 discount rate the difference is 400 000 to 500 000 per mile of

    Milling also produces a rough grooved surface which will increase the existing pavement surface area when compared to an ungrooved surface. The surface area increase is dependent on the type number condition and spacing of cutting drum teeth but is typically in the range of 20 to 30 percent which requires a corresponding increase in tack coat (20 to 30 percent more) when compared to an
