I 1 (******) I2 The Contractor shall call for locates before planing any HMA pavement. Any 3 induction loop vehicle detectors which are within the planing area shall be 4 discussed with the inspector prior to planing to see if the planing limits can be I 5 modified to save the loops. Any loops which are damaged in the planing process 6 shall be replaced prior to the final overlay. The electrical subcontractor shall be on- 7 call and the loops shall be replaced within 5 working days of the planing operation I 8 and paved within 3 working days of the loop installation. See Section 8-20 of the 9 Specifications for details on loop installation and payment. 10 11 Planing shall be performed in such a manner that the underlying pavement is not 12 torn, broken, or otherwise damaged by the planing operation. The surface of the 13 underlying pavement shall be slightly grooved or roughened sufficiently to ensure a I 14 bond when overlaid. All areas to be ground shall be completed with a grinder. The 15 use of other methods must be approved by the Engineer. 16 I 17 18 If, after planing a thin veneer layer remains, the contractor shall replane the roadway as directed by the Engineer, paid under "Additional Planing Bituminous 19 Pavement". The Contractor shall adjust their schedule at no additional cost to the 20 owner. I21 22 The planings shall become the property of the Contractor and shall be removed 23 from the right-of-way. The planings may be utilized as RAP, within the I 24 requirements of Section 5-04.2 or 9-03.21. The Contractor shall immediately 25 dispose of all other debris resulting from the planing operation in a Contractor- 26 provided site off the right-of-way. I 27 28 Immediately after grinding, the Contractor shall construct an asphalt transition 29 (temporary paper joints or ramps), on all traveled ways, wheel chair ramps, and 30 exposed manholes, inlets, catch basins, monuments, valve boxes, and other 31 structures on the street, regardless of depth in grinding. Asphalt transition must be 32 removed prior to overlay. Cast iron structures left higher than 2" must be removed I 33 and steel plates installed to protect the opening and provide a suitable driving 34 surface. 35 36 Sweeping of roadway surface shall immediately follow all grinding. Sweeping of I 37 roadway surface is required prior to tack placement and paving. 38 39 The road shall be overlayed within 3 working days after planing operation for I 40 streets without loops. On streets where loops will be replaced, the overlay shall be 41 completed within 8 working days after planing operation. 42 I 43 44 Sweepers following the grinding work will not be paid separately, and is included in the bid item "Planing Bituminous Pavement (2" Deep)", per square yard. 45 I 46 47 For mainline planing operations, the equipment shall have automatic controls, with sensors for either or both sides of the equipment. The controls shall be capable of 48 sensing the proper grade from an outside reference line, or a mat-referencing I 49 device. The automatic controls shall also be capable of maintaining the desired 50 transverse slope. The transverse slope controller shall be capable of maintaining 51 the mandrel at the desired slope (expressed as a percentage) within plus or minus 52 0.1 percent.
