The Work covered by these Specifications consists of furnishing all labor, equipment, appliances, materials and performing all operations in connection with the inspection and testing, complete in accordance with the Plans, and subject to the terms and conditions of the Contract Documents The City of Round Rock in its sole discretion will select either the Base Bid or Alternate Bid shown in the Bid Form. Only one (1) of the methods of resurfacing discussed in the following two (2) items will apply to the Work and the method to be applied will be dependent on the City's selection of either the Base Bid or Alternate Bid: The Base Bid item "In-Place Pavement Recycling" shall consist of heating, scarifying and repaving of existing asphaltic concrete pavement to a minimum depth of one inch (1 ") (Item No. 350) after any applicable milling and crack sealing has been performed. A minimum one inch (1") Type D HMAC (Item No. 340) overlay shall also be placed on top of and rolled simultaneously with the heated/scarified/repaved surface. The Type D HMAC overlay shall be virgin material without any RAP/RAS. The machine that heats, scarifies, blends, mixes and distributes the repaving shall be the same or sufficiently integral with, as approved by the Engineer, the machine that spreads and finishes the overlay. New pavement must be laid within 30 seconds after scarification begins. It is the intent of this item to provide a uniform, recycled and overlain road cross-section that exhibits a smooth vehicular ride. All obvious irregularities, low spots, high spots, or areas that exhibit a rough vehicular ride shall be corrected as approved by the Engineer at the Contractor's sole expense. This item will be measured by the square yard of surface recycled and will be paid for at the unit price shown in the Bid Form for the item which shall include full compensation for: necessary sweeping of the roadway prior to pavement recycling; removal of traffic buttons, vegetation, or other items (if present); pavement recycling; clean-up; and all other labor, materials, equipment, and incidentals necessary to provide a properly completed recycled/overlaid pavement surface, save and except the minimum one inch (1 ") Type D HMAC overlay shall be measured and paid for by the ton under the Base Bid item for "Type D HMAC Surface Course" and any required binding (recycling) agents (Item No. 351) will be measured and paid for by the gallon under the Base Bid item for "Rejuvenator Agent". 2. The Alternate Bid item "Machine-Laid Type D HMAC Overlay" shall consist of placing a Type D HMAC (Item No. 340) final surface course upon a roadway after any applicable milling and crack sealing has been performed. The Type D HMAC shall be virgin material without any RAP/RAS. Unless otherwise determined or directed by the Engineer, the thickness of the overlay will nominally be 2". The Contractor is alerted to the fact that the actual thickness of HMAC placed may vary due to milling performed or surface deviations within existing roadways. It is the intent of this item to provide an overlay that is placed by a spreading and finishing machine in a single lift that, when complete, provides for a smooth vehicular ride. The Contractor shall utilize skis or other method acceptable to the Engineer with the spreading and finishing machine to ensure the overlay will remove minor surface deviations and provide a smooth and uniform surface. All obvious irregularities, low spots, high spots, or areas that exhibit a rough vehicular ride in the overlay shall be corrected as approved by the Engineer at the Contractor's sole expense. This item will be measured by the ton of HMAC placed and will be paid for at the unit price shown in the Bid Form for the item. The unit price shall include full compensation for: necessary sweeping of the roadway prior to overlay placement; removal of traffic buttons, vegetation, or other items (if present); placement of tack or prime coats; overlay placement; clean-up; and all other labor, materials, equipment, and incidentals necessary to provide a finished and proper HMAC overlay The following three (3) items are similar for both the Base Bid and the Alternate Bid; however, the depth of milling/pavement removal, and adjustment ring depths are anticipated to be dependent upon the City's selection of either the Base Bid or Alternate Bid: 3. The bid item "Surface Milling" shall be in accordance with the governing technical specifications (Item No. 315). The surface milling depth shall be one inch (1") (if the Base Bid is selected by the City) or two inches (2") (if the Alternate Bid is selected by the City) and shall match the depth called out in the plans. The Owner requires surface milling of all cul-de-sacs or other miscellaneous areas to the depth and limits determined by the Engineer. Surface milling may also be required at intersections as discussed in item 4 below. The Contractor shall consult with the Engineer prior to milling to verify the correct mill depths and to otherwise coordinate the milling to achieve a subsequent overlay that will be as best as practicable. Any residual loose milling material left on surfaces after milling shall be cleaned up by the Contractor as soon as practicable following milling. Surface milling shall be measured by the square yard of surface milled (regardless of depth) and shall be paid for at the unit price shown in the Bid Form for the item. 4. Unless otherwise approved or directed by the Engineer, where a street being recycled or overlaid longitudinally intersects another street or Portland cement concrete pavement or valley gutter, the pavement on the street being recycled or overlaid shall be removed and replaced from the intersection to a point fifteen feet (15') from the intersection. The depth of removal shall be two inches (2") at the intersection transitioning to the existing pavement surface fifteen feet (15') from the intersection. The Contractor shall provide any saw cutting of the pavement necessary to protect abutting pavement to remain at no additional cost to the Owner. The replacement pavement shall be measured and paid for under the item "Type D HMAC Surface Course" (if the Base Bid is selected by the City) or "Machine-Laid Type D HMAC Overlay" (if the Alternate Bid is selected by the City) regardless of the depth. Where two or more streets at a street intersection are being recycled or overlaid, the limits of pavement removal as discussed above shall be determined by the Engineer in consultation with the Contractor. The Owner may elect to replace the pavement on all "legs" of a street intersection even if one or more of the streets at the intersection is not scheduled for overlay in this project. Furthermore, the Owner may elect to replace the pavement on asphalt driveways that intersect a street being recycled or overlaid. When the Owner elects to remove and replace the pavement on an asphalt-surfaced driveway that intersects a street being recycled or overlaid and the driveway pavement directly abuts asphalt pavement of the street, the removal and replacement of the driveway pavement shall be in accordance with this section, except that the driveway pavement shall be removed and replaced from the intersection to a point ten feet (10') from the intersection at a depth of two inches (2") for the entire ten feet (10') unless otherwise directed or approved by the Engineer. The Contractor shall exercise care in removing and replacing pavement at intersections to ensure that the finished intersections will drain properly. 5. The bid items "Manhole Adjustment" and "Valve Can Adjustment" shall consist of installing a cast iron adjustment ring for existing manholes and valves within any paved area that will require a height adjustment to bring the manhole or valve to the appropriate finished grade prior to placement of final paving. The adjustment rings shall be as manufactured by East Jordan Iron Works or approved equal. The Contractor shall be responsible for determining the appropriate size adjustment ring, determining whether or not a sloping ring is required, and selecting a ring that is compatible with a given manhole or valve. Adjustment rings shall be installed in accordance with the manufacturer's recommendations and upon installation, adjustment rings shall fit snugly to the respective ring being adjusted and, upon placement of the cover, shall not loosen or cause improper rocking of the cover when subjected to vehicular traffic. This item will be measured by each manhole or valve adjustment ring installed and shall be paid for at the unit price shown in the Bid Form for the respective item. The unit price shall include full compensation for: cleaning the existing manhole or valve ring and cover as necessary to determine the appropriate ring required; providing and installing each ring; clean up; and all other labor, materials, equipment, and incidentals necessary to perform the work. If any wastewater cleanout castings require adjustment, such adjustment shall be similar to that for valve cans and shall be paid for per each under the bid item "Valve Can Adjustment". The following nine (9) items will apply the same to either the Base Bid or Alternate Bid: 6. The bid item "Pavement Repair" shall consist of saw cutting the existing pavement, excavating (Item No. 111) the existing pavement and subsurface material to a depth of twelve inches (12"), compacting the remaining base or subgrade (Item No. 201), installing multiple lifts of Type A or Type B HMAC (Item No. 340) base course. Prior to placement of the base course, the Contractor shall proof roll (Item No. 236S) the excavated area and the Contractor and the Engineer shall examine the excavated area for suitability/soundness. As determined by the Contractor and/or as directed by the Engineer, any soft/unstable areas shall be further excavated until development of a firm, stable subgrade and replaced by increasing the thickness of the base course. The finished surface of the repaired area and the repaired area/existing surface interface shall exhibit a smooth vehicular ride. This item shall be measured by the ton of HMAC placed and shall be paid for at the unit price shown in the Bid Form for the item. The unit price shall include full compensation for: all saw-cutting; excavation (regardless of depth or material encountered); removal and disposal of excavated materials; proof rolling; subgrade compaction; tack and/or prime coats; placement of HMAC; clean-up; and all other labor, materials, equipment, and incidentals necessary to perform the work.
