The overlay shall be <br /> in accordance with State Standard Specifications, Section 39. Aggregate <br /> gradation shall be consistent with the existing surfacing material. (See <br /> EXHIBIT 1: LONGITUDINAL CUTTING OF COUNTY ROADWAYS.) <br /> 3. Cross-Cutting: <br /> Cross-cutting is allowed at a minimum interval of one hundred fifty (150) <br /> feet. At each cross-cut location a minimum of ten (10) feet each side of <br /> trench shall be planed and resurfaced with one (1) inch asphalt concrete. <br /> If cross cuts are within the 150 feet minimum interval, the entire section <br /> between the first and last cross cut shall be planed and resurfaced with <br /> one (1) inch asphalt concrete.
