P26-05 SCOPE OF WORK

1.0 Overview- The contractor or contractors shall provide asphalt and or both concrete and asphalt services for our facilities as per the specifications herein. This RFP intends to establish a contract for a pool of asphalt and concrete contractors. Necessary work including paving, patching, milling, paving overlay, striping, handicapped parking dimensions layout and painting, fire lane painting and hydrant marking and striping, traffic Lanes, and seal coating at FCS Schools. This RFP will also cover the repair and construction of existing flat concrete work and repair. Requirements will be different at each location on an as‐needed basis. Services shall include all necessary labor, materials, tools, and equipment to complete the project.

2.1 Paving Specifications Asphalt Removal and Replacement

2.1.1 Prior to removing the asphalt, the full depth of the area(s) should be marked and saw cut, creating a straight, uniform, and smooth patch.

2.1.2 Asphalt spoils and debris must be removed entirely from the sub‐base (a minimum of 6”) and disposed of at an approved off‐site dumping facility.

2.1.3 Edges of the work must be clean, straight, and vertical. Any chipping, cracking, crushing, or damage to the adjacent pavement (surface) must be sawed, cut, removed, and replaced.

2.1.4 Drainage plans are required prior to starting subgrade preparation. Soil should be excavated and fine‐graded. All stormwaters should be pitched to stormwater management systems. There should be no standing ponds of water. The surface should be flat without crowning. The contractor is responsible for all efforts to ensure the proper surface slope and eliminate “water ponding.”

2.1.5 A stabilized subgrade is required. Repair and recompact subgrade as needed. Lime application or pavement reinforcing geo grids are acceptable.

2.1.6 The subbase should be minimum 4 inches. Acceptable subbases are asphalt binder, crushed limestone, or recycled concrete. Compact with roller and apply herbicide to prevent vegetation growth.

2.1.7 A two (2) inch top layer of hot mix asphalt concrete (HMAC) should be compacted at a temperature no less than 175 degrees F. This should also be referenced in section 2.4.

2.1.8 Mill/grind areas along edges, curbs, manholes, inlet grates, and other concrete areas so that new asphalt has proper elevation transitions and stormwater runoff. A tack coat emulsion must also be applied to the edges of the existing asphalt surrounding the repair/replacement areas.

2.1.9 Hot mix asphalt concrete (HMAC) shall be placed at no less than 250 degrees F and no higher than 300 degrees F.

2.1.10 Before placing HMAC material, the minimum outside temperature must be 40 degrees F and rising. A clean and dry substrate should accompany.

2.1.11 In all instances, work must comply with current industry standard.

2.2 Paving Overlay Asphalt and Concrete Services

2.2.1 Before starting subgrade preparation, drainage plans are required. Soil should be excavated and fine‐graded. All stormwaters should be pitched to stormwater management systems. There should be no standing ponds of water. The surface should be flat without crowning. All efforts to ensure the proper surface slope and eliminate “water ponding” are the contractor's responsibility.

2.2.2 Tack coat and apply 1 inch of perma‐flex and 1 inch of hot mix asphalt concrete (HMAC).

2.2.3 Mill/grind areas along edges, curbs, manholes, inlet grates, and other concrete areas so that new asphalt has proper elevation transitions and stormwater runoff. A tack coat emulsion must also be applied to the edges of the existing asphalt surrounding the repair/replacement areas.

2.2.4 Hot‐mix asphalt concrete (HMAC) shall be placed at a temperature of at least 250 degrees F and at a temperature of at least 300 degrees F.

2.2.5 A minimum outside temperature of 40 degrees F and rising must exist before the new hot mix material and a clean and dry substrate are placed.

2.3 Patching Pavement

2.3.1 Prior to removing the asphalt, the full extent of the area(s) should be marked and saw cut, creating a straight, uniform, and smooth patch.

2.3.2 Asphalt spoils and debris must be removed entirely from the sub‐base (a minimum of 6”) and disposed of at an approved off‐site dumping facility.

2.3.3 Drainage plans are required prior to starting subgrade preparation. Soil should be excavated and fine‐graded. All stormwaters should be pitched to stormwater management systems. There should be no standing ponds of water. The surface should be flat without crowning. The contractor is responsible for all efforts to ensure the proper surface slope and eliminate “water ponding.”

2.3.4 Saw cut, remove damaged asphalt, and replace with two (2) inches of asphalt binder and one (1) inch of hot mix asphalt concrete (HMAC).

2.3.5 Mill/grind areas along edges, curbs, manholes, inlet grates, and other concrete areas so that new asphalt has proper elevation transitions and stormwater runoff.

2.3.6 Completed patches must meet the existing grade of adjacent asphalt, concrete, etc.

2.3.7 Hot‐mix asphalt concrete (HMAC) shall be placed at a temperature of at least 250 degrees F and at a temperature of at least 300 degrees F.

2.3.8 A two (2) inch top layer of hot mix asphalt concrete (HMAC) should be compacted at a temperature no less than 175 degrees F.

2.3.9 A minimum outside temperature of 40 degrees F and rising must exist before the placement of new hot mix asphalt concrete (HMAC) material and a clean and dry substrate.

2.4 Full Depth Reclamation Asphalt and Concrete Services

2.4.1 Mechanical broom & force air clean the surface to receive the new pavement of all loose stones, dirt, and debris.

2.4.2 Mill the existing surface down 3” and haul off all debris to an approved dump facility. If there is not a 90-degree vertical edge where the milling begins and ends, then the area needs to be saw cut to create a proper 90-degree vertical edge to tie into.

2.4.3 Mill/grind areas along edges, curbs, manholes, inlet grates, and other concrete areas so that new asphalt has proper elevation transitions and stormwater runoff.

2.4.4 Any asphalt that is left over after milling along with a portion of the subgrade will be pulverized to a depth of 10” and stabilized using 60 lbs/SY of Portland cement. After Portland cement is mixed into the subgrade the area will then be graded and compacted. Water will be applied with ample water equipment to then activate cement. Prior to water application and during the grading process, if contractor finds that the fluff rate of the pulverization process has created excess subgrade, contractor is responsible to appropriately clip the subgrade to bring it to correct grade and haul off and dispose of excess materials. Such additional costs incurred should be considered in base price as a change order will not be permitted/accepted for such excess materials/time/equipment/hauling/etc.

2.4.5 Apply tack coat to promote adhesion between existing stabilized subgrade surface and the new pavement surface. Area will then be paved with 2 inches (compacted thickness) of Type-2 9.5mm Surface Asphalt and properly compacted.

Thoroughly clean the routed reservoir with compressed air or other satisfactory methods to remove dust or debris. Seal Cracks with approved Sealant per manufacturer’s application specifications. Fill cracking as close to flush as possible; a thin squeegeed band‐aid is acceptable.

2.5.3 Seal‐coat material to be high quality, polymer‐modified coal‐tar emulsion meeting federal specification R-P-355e. Apply two (2) layers of seal coating. Don't allow vehicular traffic on the pavement until the sealer has cured enough not to become marked.
