00620.41 685 Section 00620 - Cold Plane Pavement Removal Description
00620.00 Scope - This Work consists of removing existing Pavement to prepare a foundation for
placing new Surfacing. Equipment
00620.20 Equipment - Provide self -propelled planing machines or grinders:
• Capable of loosening Pavement material. • Capable of accurately establishing profile grades within a tolerance of 0.02 foot by referenc e from either the existing Pavement or from independent grade control. • With a positive means for controlling cross -slope elevations. • With a totally enclosed cutting drum with replaceable cutting teeth. • With an effective means of removing loosened material from the surface and preventing dust from escaping into the air. • Capable of providing a true cross -slope grade that will allow placement of overlay Pavement to a uniform thickness. Construction
00620.40 Pavement Removal :
a.General - Remove the existing Pavement to the depth, width, grade and Cross Section shown or as directed. The use of a heating device to soften the Pavement is not allowed.
b.Depth 1 inch to 2 inches - If the depth of the existing Pavement to be removed is 2 inches or less, but more than 1 inch and the section will be under traffic, schedule the Work so the full width and length of travel lanes Pavement can be removed during the same shift. Remove the Shoulder area within 24 hours.
c.Depth over 2 inches - If the depth of the existing Pavement to be removed is over 2 inches and the section will be under traffic, schedule the Work so the full width and length of the travel lanes and Shoulder s can be removed, leaving no longitudinal or transverse drop -offs, during the same shift.
d.Pavement Removal Alternative - If unable to complete the Pavement removal according to 00620.40(b) and (c), then within the same Day construct a wedge of asphalt concrete, at a Slope of 1V:10H or flatter along each exposed longitudinal drop-off, and 1V:50H or flatter along each exposed transverse drop- off. Place wedges completely across the milled area at intersections, points of beginning and ending of the milling operation, and around manholes, valve boxes and other Structure s. Longitudinal drop-offs of 1 inch or less do not require a wedge. Maintain wedges as long as the area remains under traffic or until Pavement is replaced. Remove and dispose of wedges before placing new Pavement .
e.Warning Signs - Provi de warning signs as required where abrupt or sloped drop-offs occur at the edge of the existing or new surface according to Sections 00221 and 00222 .
00620.41 Surface Tolerance - Test with a 12-foo t straightedge furnished and operated by the
Contractor, as directed. The variation of the top of the ridges from the testing edge of the straightedge, between any two ridge contact points, shall not exceed 1/4 inch. 00620.42
00620.42 Disposal of Materials - Dispose of all materials according to 00290.20.
00620.43 Maintenance Under Traffic - If the cold planed Pavement surface will be exposed to
traffic, sweep and clean prior to allowing traffic to use the Roadway . Measurement
00620.80 Measurement - The quantities of c old plane Pavement removal will be measured on the
area basis, in place. When the depth of Pavement to be removed is variable, the depth as shown is an estimate and is approximate only. No guarantee is made that the actual depth will be the same as the estimated depth. Payment
00620.90 Payment - The accepted quantities of Work performed under this Section will be paid for
at the Contract unit price, per square yard, for the item "Cold Plane Pavement Removal, ____ Deep". The depth will be inserted in the blank. If the depth is variable, the depth range will be inserted in the blank. Payment will be payment in full for furnishing all Equipment , labor, and Incidental s necessary to complete the Work as specified. No separate or additional payment will be made for temporary wedges constructed, maintained, and removed under 00620.40(d), or for replacem ent of cutting teeth.
