MILLING ASPHALT PAVEMENT DESCRIPTION Perform the work covered by this section including, but not limited to, milling and re-milling the pavement at locations, depths, widths and typical sections indicated in the contract; cleaning the milled surface; loading, hauling and stockpiling the milled material for use in recycled asphalt mixtures; and disposal of any excess milled material. Except where the milled material is used in the work or where otherwise directed, provide areas outside the right of way to dispose of milled material, which shall be property of the Contractor. EQUIPMENT Use a self-propelled unit capable of removing the existing asphalt pavement to the depths, widths and typical sections shown in the contract. Use milling machines designed and built exclusively for pavement milling operations and with sufficient power, traction and stability to accurately maintain depth of cut and slope. Use milling machines equipped with an electronic control system that will automatically control the longitudinal profile and cross slope of the milled pavement surface. Accomplish this through the use of a mobile grade reference, an erected string line, joint matching shoe, slope control systems or a combination of approved methods. Use an erected fixed stringline when required by the contract. Otherwise, use a mobile grade reference system capable of averaging the existing grade or pavement profile over at least 30 ft. Use either a non-contacting laser or sonar type ski systems with at least 4 referencing stations mounted on the milling machine at a length of at least 24 ft. Coordinate the position of the grade control system such that the grade sensor is at the approximate midpoint of the mobile reference system. Use a machine capable of leaving a uniform surface suitable for handling traffic without damage to the underlying pavement structure. Use a milling machine and other loading equipment capable of loading milled material to be used in other parts of the work without segregation. Provide additional equipment necessary to satisfactorily remove the pavement in the area of manholes, water valves, curb, gutter and other obstructions. Equip the milling equipment with a means of effectively limiting the amount of dust escaping from the removal operation in accordance with Federal, State and local air pollution control laws and regulations. CONSTRUCTION METHODS Mill the existing pavement to restore the pavement surface to a uniform longitudinal profile and cross section in accordance with typical sections shown in the plans. Where indicated in the contract, remove pavement to a specified depth and produce a specified cross slope. Mill intersections and other irregular areas unless otherwise directed by the Engineer. The Contractor may elect to make multiple cuts to achieve the required depth of cut or cross slope required by the plans. 105 DocuSign Envelope ID: 797C32F6-C1CE-44EB-BF17-813A5939396C
