The Table of Contents for this section is available.
The work covered by this section consists of milling asphalt pavement at locations, depths, widths, and typical sections indicated in the plans and special provisions or as directed by the Engineer.
The work also includes removing, transporting, and disposing of the milled material; and cleaning the milled pavement surface.
The milled material shall become the property of the Contractor. All milled material shall be disposed of by the Contractor in areas provided by him which are outside the right of way, except where the milled material is used in the work.
Equipment shall include a self propelled unit capable of removing the existing asphalt pavement to the depths, widths, and typical sections shown in the plans. The equipment shall have been designed and built exclusively for pavement milling operations and shall have sufficient power, traction, and stability to accurately maintain depth of cut and slope. The milling machine shall be equipped with a grade control system which will automatically control the longitudinal profile and cross slope of the milled surface by the use of one or more skid sensors moving along the pavement surface. The machine shall be capable of leaving a uniform surface suitable for handling traffic without excessive damage to the underlying pavement structure. The milling machine and other loading equipment shall be capable of loading milled material to be used in other parts of the work without excessive segregation.
Additional equipment necessary to satisfactorily remove the pavement in the area of manholes, water valves, curb and gutter, and other obstructions shall be provided.
The milling equipment shall be equipped with a means of effectively limiting the amount of dust escaping from the removal operation in accordance with local, State, and Federal air pollution control laws and regulations.
612-3 CONSTRUCTION REQUIREMENTS.
The existing pavement shall be milled in a manner which will restore the pavement surface to a uniform longitudinal profile and cross section at the locations and in accordance with typical sections shown in the plans. Where indicated in the plans or Project Special Provisions, removal shall be to a specified depth and shall produce a specified cross slope. The Contractor shall mill intersections and other irregular areas as indicated in the plans, Project Special Provisions, or as 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.
The longitudinal profile of the milled surface shall be established by a mobile string line on the side of the cut nearest the centerline of the road or as directed by the Engineer. The cross slope of the milled surface shall be established by an automatic cross slope control mechanism or by a second skid sensing device located on the opposite edge of the cut. The Engineer may waive the requirement for automatic grade and cross slope controls where conditions warrant.
The milling equipment shall be operated in such a manner as to prevent damage to the underlying pavement structure, utilities, drainage facilities, curb and gutter, paved surfaces outside the milled area, and any other appurtenances. The milled pavement surface shall be reasonably smooth and free of excessive scarification marks, gouges, ridges, continuous grooves, or other damage as determined by the Engineer. Any leveling or patching required as a result of negligence by the Contractor shall be repaired with hot asphalt plant mix at no cost to the Department and in a manner acceptable to the Engineer. The Contractor shall coordinate the adjustment of manholes, meter boxes, and valve boxes with the milling operation.
The Engineer may require remilling of any area exhibiting defects such as laminations or defects. If the defects are determined to be the result of the Contractor's negligence, then measurement for the remilling, as specified in Article 6125, will not be made. If however, the Engineer directs the remilling of an area which is not due to the Contractor's negligence, measurement of the remilled area will be made under provisions of Article 6125.
The milled pavement surface shall be thoroughly cleaned of all loose aggregate particles, dust, and other objectionable material by the use of power brooms, power blowers, power vacuums, or other means. Disposal or wasting of oversize pieces of pavement or loose aggregate material will not be permitted within the right of way.
The pavement removal operations shall be conducted to effectively minimize the amount of dust being emitted. The operation shall be planned and conducted so that it is safe for persons and property adjacent to the work including the traveling public.
Removal of the existing pavement shall be to the depth required by the plans or project special provisions. The Engineer may vary the depth of milling by not more than one inch. In the event the directed depth of milling per cut is altered by the Engineer more than one inch, either the Department or the Contractor may request an adjustment in unit price under the provisions of Article 1043. In administering the provisions of Article 1043 the Department will give no consideration to value given to reclaimed asphalt pavement unless that value has been included in the unit bid price for recycled plant mix.
The provisions of Article 1043 will not apply to the item of "Incidental Milling".
(A) General:
The quantity of milled asphalt pavement to be paid for will be the actual number of square yards of pavement surface which has been milled in accordance with the requirements of this section. In measuring this quantity, the length will be the actual length milled, measured along the pavement surface. The width will be the width required by the plans or directed by the Engineer, measured along the pavement surface.
(B) Milling Asphalt Pavement, ___________ Inch Depth:
For each and every square yard that the Engineer directs to be milled; including that requiring any additional equipment necessary to remove pavement in the area of manholes, water valves, curb and gutter, and other obstructions; measured as provided in Subarticle 6125(A); compensation will be made as provided in Articles 6124 and 6126. Where the Engineer directs multiple cuts to achieve the final depth, measurement will be made for each cut. Where the Contractor elects to make multiple cuts to achieve the final depth, no additional measurement will be made.
(C) Incidental Milling:
Where the Contractor is required by the plans to mill irregular areas and intersections or is directed to remill areas whose length is less than 100 feet, measurement will be made as provided in Subarticle 6125(A) for each cut he is directed to perform. Where the Contractor elects to make multiple cuts to achieve the final depth, no additional measurement will be made.
The quantity of milled asphalt pavement, measured as provided in Article 6125, will be paid for at the contract unit price per square yard for "Milling Asphalt Pavement, ________ Inch Depth" or "Incidental Milling", as the case may be.
Where the depth of milling varies from the required depth, no adjustment in the contract unit price for "Milling Asphalt Pavement, _________ Inch Depth" will be made except as provided in Article 6124.
The above prices and payments will be full compensation for all work covered by this section, including but not limited to milling and remilling the pavement, cleaning the milled surface, loading, hauling, stockpiling the milled material for use in recycled asphalt mixtures, and disposal of any excess milled material.
Payment will be made under:
Milling Asphalt Pavement, ________ Inch Depth Square Yard
Incidental Milling Square Yard
