Item Article/Section
a.Self-Propelled Milling Machine ........................................................... 1101.16 CONSTRUCTION REQUIREMENTS Art. 440.03 Removal of Existing Pavement and Appurtenances
440.03 General. All existing pavement, including surface courses, base
courses, and stabilized subbases, and other appurtenances as listed above, which interfere with construction work shall be completely removed as shown on the plans or as directed by the Engineer. When portions of existing pavement and appurtenances are to remain in place, provisions shall be made for satisfactory transitions between replacements and the portions remaining in place. A full depth, perpendicular, straight joint shall be sawn at the ends and all edges of portions to be removed. Any damage done to the existing pavement or appurtenance to remain in place shall be repaired or removed and replaced as directed by the Engineer. The thickness of the existing pavement to be removed, including overlays and other appurtenances, will be shown on the plans. Gutter removal shall include the complete removal of all inlets, outlets and entrances that are contained within the limits of the designated removal. The removal of outlets shall include the entire discharge trough and end curtain wall for trough type outlets and the concrete box and outlet pipe for drop box type outlets. Paved ditch removal shall include the complete removal of all anchor walls and cut-off walls that are contained within the limits of the designated removal. Any excavation made by the Contractor for the removal shall be replaced. The excavated space shall be filled with material satisfactory to the Engineer and placed according to Section 205 at no additional cost to the Department.
440.04 HMA Surface Removal for Subsequent Resurfacing. The existing
HMA surface shall be removed to the depth specified on the plans with a self- propelled milling machine. The temperature at which the work is performed, the nature and condition of the equipment, and the manner of performing the work shall be such that the milled surface is not torn, gouged, shoved or otherwise damaged by the milling operation. Sufficient cutting passes shall be made so that all irregularities or high spots are eliminated to the satisfaction of the Engineer. When tested with a 16 ft (5 m) straightedge, the milled surface shall have no surface variations in excess of 3/16 in. (5 mm). Removing the existing HMA surface to the required depth adjacent to structures in the pavement surface such as drain castings and utility covers shall be accomplished in a manner satisfactory to the Engineer using either machine or hand methods. Castings for existing utility or drainage structures within the pavement which are exposed to traffic after the pavement has been milled shall be protected according to Article 603.07. Milled pavement shall be resurfaced within ten calendar days.
440.05 Median Removal Partial Depth. The portland cement concrete
median shall be removed to the depth specified with a self-propelled milling machine.
440.06 Disposal of Material. Materials resulting from the removal of existing
pavement and appurtenances as herein specified shall be disposed of according to
Article 202 — 03.
Removal of Existing Pavement and Appurtenances Art. 440.07
440.07 Method of Measurement. This work will be measured for payment as
follows.
a.Contract Quantities. The requirement for use of contract quantities shall be according to Article 202.07(a).
b.Measured Quantities. Pavement removal, driveway pavement removal, and paved shoulder removal will be measured for payment in place and the area computed in square yards (square meters). HMA surface removal for subsequent resurfacing will be measured for payment in place and the area computed in square yards (square meters) for each specified increment thickness of material removed. Curb removal, gutter removal, combination curb and gutter removal and paved ditch removal will be measured for payment in feet (meters). The measurement for curb removal and combination curb and gutter removal will be made along the face of the curb. The measurement for gutter removal and paved ditch removal will be made along the flow line. Sidewalk removal, median removal and median removal partial depth will be measured for payment in place and the area computed in square feet (square meters). Removal of any of the items listed above outside the designated limits as shown on the plans or as directed by the Engineer will not be measured for payment.
c.Adjustment of Quantities. The quantity of pavement removal and paved shoulder removal will be adjusted if their respective thickness varies more than 15 percent from that shown on the plans. The quantity will be either increased or decreased according to the following table. % change of thickness % change of quantity 0 to less than 15 15 to less than 20 20 to less than 30 30 to less than 50 If the thickness of the existing pavement varies by 50 percent or more from that shown on the plans, the character of the work will be considered significantly changed and an adjustment to the contract will be made according to Article 104.02. When an adjustment is made for variations in pavement or shoulder thickness, a resulting adjustment will also be made in the earthwork quantities when applicable. No adjustment will be made for variations in the amount of reinforcement. Art. 440.08 Hot-Mix Asphalt Pavement (Full-Depth) on Rubbilized PCC
