Article 1 — Description
Plane, or plane and texture, existing asphalt concrete pavement, asphalt -stabilized base, or concrete pavement.
Article 2 — Equipment
The Engineer may require demonstration of the equipment’s capabilities.
2.1 Planing Machine . Use planing machines that:
have a minimum 6- ft. cutting width except for work areas less than 6 ft. wide; are self -propelled with enough power, traction, and stability to maintain an accurate depth of cut and slope; can cut in one continuous operation: 4 in. of asphalt concrete pavement, 1 in. of concrete pavement, or a combination of 2 in. of asphalt concrete pavement and 1/2 in. of concrete pavement; use dual longitudinal controls capable of operating on both sides automatically from any longitudinal grade reference, which includes string line, ski, mobile string line, or matching shoe; use transverse controls with an automatic system to control cross slope at a given rate; use integral loading and reclaiming devices to allow cutting, removal, and discharge of the material into a truck in one operation; and include devices to control dust created by the cutting action.
2.2 Manual System . Use a manual system that can achieve a uniform depth of cut, flush to all inlets, valve
covers, manholes, and other appurtenances within the paved area. Use of a manual system is allowed for areas restricted to self -propelled access and for detail pavement removal.
2.3 Sweeper . Use a street sweeper to remove cuttings and debris from the planed or textured pavement unless
otherwise approved. Equip the sweeper with a water tank, a dust control spray assembly, both a pick -up and a gutter broom, and a debris hopper.
Article 3 — Construction
3.1 Grade Reference. Place grade reference points at maximum intervals of 50 ft. in accordance with Item 5,
“Control of the Work,” when required. Use the control points to set the grade reference. Support the grade reference so the maximum deflection does not exceed 1/16 in. between supports.
3.2 Planing and Texturing. Vary the speed of the machine to leave a grid or other pattern type with
discontinuous longitudinal reach. Remove the pavement surface for the length, depth, and width shown on the typical section and to the established line and grades. Remove pavement to vertical lines adjacent to curbs, gutters, inlets, manholes, or other obstructions. Do not damage appurtenances or underlying pavement. Provide a planed surface that has a uniform textured appearance and riding surface. Surface should be free of gouges, continuous longitudinal grooves, ridges, oil film, and other imperfections of workmanship. Leave a uniform surface of concrete pavement free of asphalt materials when removing an asphalt concrete pavement overlay. 438 Provide a minimum texture depth of not less than 0.05 in. when an overlay on the planed pavement is not required. Stop planing operations when surface texture depth is not sufficient. Never damage armor joints and other appurtenances. Provide a pavement surface that, after planing, has a smooth riding quality and is true to the established line, grade, and cross -section. Provide a pavement surface that does not vary more than 1/8 in. in 10 ft. Evaluate this criterion using a 10- ft. straightedge placed parallel to the centerline of the roadway. Deviations will be measured from the top of the texture. Correct any point in the surface not meeting this requirement. Sweep pavement and gutter. Leave pavement and curb clean.
3.3 Edge Treatments. Sl ope vertical or near vertical longitudinal faces in the pavement surface for areas under
traffic in conformance with the requirements on the plans at the end of the day. Taper transverse faces to provide an acceptable ride.
3.4 Salvaged Materials. The Contractor will retain ownership of planed materials unless otherwise shown on the
plans. Stockpile salvaged materials at locations shown on the plans. Prepare the stockpile site by removing vegetation and trash and providing proper drainage. Keep salvaged paving material free of contamination during its removal, transportation, and storage. Place different types or qualit ies of salvaged asphalt paving material into separate stockpiles. Dispose of unsalvageable material in conformance with applicable federal, state, and local regulations.
Article 4 — Measurement
This Item will be measured by the square yard of surface area for each pavement type, including asphalt concrete pavement and concrete pavement. Measurement will be based on the depth shown for each bid item, within the limits shown on the plans, regardless of the number of passes required. Only one bid item for each pavement type will apply to any one location.
Article 5 — Payment
The work performed and materials furnished in accordance with this Item and measured as provided under “Measurement” will be paid for at the unit price bid for “Planing and Texturing Asphalt Concrete Pavement,” “Planing and Texturing Concrete Pavement,” “ Planing Asphalt Concrete Pavement,” or “Planing Concrete Pavement” of the depths specified. The planing of concrete pavement to remove all asphalt concrete pavement in accordance with Article 354.3., “Construction,” will be subsidiary to the planing of asphalt concrete pavement of the depth shown on the plans. This price is full compensation for removing all material to the depth shown; texturing the pavement surface when texturing is shown in the bid item description; loading, hauling, and unloading; stockpiling or disposing of material; sweeping; tapering or sloping longitudinal or transverse joints in accordance with Section 354.3.3., “Edge Treatments”; and equipment, labor, tools, and incidentals. Demonstration work to receive approval for use of equipment will not be paid for unless work is performed in accordance with the Contract and is accepted.
