SECTION 935 — REMOVING ASPHALT PAVEMENT BY MICRO-MILLING — REMOVING ASPHALT PAVEMENT BY MICRO-MILLING
935.01 Description.
This work includes the removal of asphalt material using micro-milling to the specified depth. See SECTION 401 for additional, applicable information.
935.02 Materials.
Not applicable.
935.03 Construction Methods.
Equipment. Ensure that the milling equipment for removing the asphalt pavement is designed specifically for grinding asphalt surfaces to close tolerances and is operated at a rate that will avoid tearing and gouging of the pavement surface. Ensure that t he equipment can accurately establish profile grades and cross slopes and has a positive means for preventing any dust resulting from the operation from escaping into the air. Use a n averaging ski not less than 25 ft in length on each side of the pavement removal equipment on all limited- access highways and on other types of highways when indicated in the Contract Documents. Control Strip. On the first day of milling, grind a control strip at least 500 ft long with uniformly textured surface and cross section. Ensure that t he milled pavement surface has a transverse pattern 0.3 in. or less between the centers of each strike area and that the macrotexture is 1/16 in. or less as measured using ASTM E965. Pavement Grinding. Upon the approval of the control strip by the Engineer, grind all areas designated for micro-milling using the identical procedures, settings , and speed, and ensure that the work conform s to the requirements for the control strip. When micro-milling impacts areas that include bridge joint s that will remain in place , mill the pavement leading up to and away from the joints with the micro-milling machine. Mill any small areas that remain with a trimmer designed to come close to structures. Do not use a skid steer with attachment for this operation. Construct temporary ramps using Class 4.75 or Class 9.5 HMA and rosin paper or equivalent for debonding. Do not allow any asphalt cuttings to remain on the Project at the end of the workday.
935.04 Method of Measurement.
Removing Asphalt Pavement by Micro-Milling will be measured by the number of square yards of pavement removed.
