NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) January 1, 202 4 Volume 2 SECTION 490 - COLD MILLING
490-1 DESCRIPTION. This work shall consist of the milling, shaping and removal of portions of
existing surfaces by a cold milling process, and subsequent cleaning, utilizing equipment and procedures meeting the requirements in this specification. The work shall consist of Miscellaneous Cold Milling or Production Cold Milling of bituminous or portland cement concrete as indicated in the contract documents and as shown on the plans.
490-2 Materials
490-2.01 Equipment. Milling machines shall be power operated, self -propelled machines capable of
removing the desired thickness of existing surfaces. The machines shall have sufficient power, traction and stability to accurately maintain depth of cut and slope. They shall be capable of producing a finished profile and cross slope to within 1/4 inch of that required and shall produce a uniform surface texture free from gouges and ridges greater than 3/8 inch in depth. The machines shall be equipped with a means to control dust and other particulate matter created by the cutting action. The machines shall have an integral loading system or sufficient equipment shall be provided to accomplish complete removal of milled material at a rate equivalent to the milling rate. Vacuum trucks, street sweepers or power brooms shall be used to clean the milled surfaces. The Engineer may disallow the use of power brooms in urban, residential or other sensitive areas if the dust raised by the broom is deemed by the Engineer to be obj ectionable.
490-2.02 Disposal of Material. Material removed during the milling process, including foreign debris
within or on the pavement, shall become the property of the Contractor and shall be disposed of at a site obtained by the Contractor.
490-3 Construction Details
490-3.01 General. Milling shall be performed at the locations and in accordance with the details
indicated on the plans. When indicated on the plans, profile and cross slope shall be controlled by a taut reference string line. The reference elevation and string line shall be established by the Contractor and subject to the approval of the Engineer. Areas not accessible to the milling machine, such as around and/or adjacent to inlets, manholes, curbs and transverse joints on structures, may be removed by a small milling machine, handwork or other methods approved by the Engineer. All milled material, including that removed by other means, shall be immediately removed from the milled surfaces and adjacent surfaces. Surfaces shall be cleaned of all fines and dust prior to opening to traffic. The Contractor shall conduct operations i n such a manner that dust is controlled and is not objectionable. Milled and adjacent surfaces shall be cleaned again, as directed by the Engineer, prior to the placement of tack coats, or pavement courses if traffic has been allowed on the milled surface and/or if more than 48 hours have elapsed since the initial cleaning. The Contractor shall maintain drainage at catch basins, according to the details shown on the plans, or in a manner approved by the Engineer. When working adjacent to traffic, the Contractor shall immediately remove material that is spilled on the traveled way. Milled surfaces to be overlaid with asphalt concrete shall be covered with at least a single course of asphalt concrete before the end of the paving season. Portland cement concrete overlays shall be completed over milled surfaces before the end of the pa ving season. Damage to milled surfaces resulting
