This Section has potential for the incorporation of materials with recycled content. It includes reuse of site generated waste asphalt and recycled base material. There may be an opportunity for using asphalt with recycled content of clean asphalt waste or rubber tires.
Use for min. HMA paving. See WisDOT Specs for Highway & Structure Construction for more thorough specs. See Wisconsin Asphalt Pavement Association Design Guide for assistance in selecting thicknesses, pavement types, aggregate gradation, and binder grading.

SECTION 02513 — ASPHALT CONCRETE PAVING


PART 1 — GENERAL

1.01 DESCRIPTION

The extent and thickness of asphalt paving and base is shown on the Drawings. Preference will be given to materials with recycled content.

1.02 STANDARDS

Except as modified by the requirements of these Contract Documents comply with Section 401 of the current edition of the Wisconsin Department of Transportation Standard Specifications for Highway and Structure Construction.

In-place compacted HMA paving will not be acceptable if exceeding the following tolerances:
• thickness of base course, not more than 1/2" plus or minus.
• thickness of surface course, not more than 1/4", plus or minus.
• base course surface smoothness, not more than 1/4" when measured with a 10'
straightedge.
• wearing course surface smoothness, not more than 3/16" when measured with a 10' straightedge.

1.03 JOB CONDITIONS

Do not apply tack coats when temperature is below 50º F or when base is wet. Apply asphalt concrete paving only when temperature is above 40º F and when base is dry.

Delete below if not required for project.
1.04 QUALITY ASSURANCE

Provide and maintain a quality control program. Quality assurance testing may be requested by the Owner at the Owner’s expense.

1.05 SUBMITTALS

Provide the Architect with a documented mix design report. Include percentage and type of recycled content.


PART 2 — PRODUCTS

2.01 MATERIALS

Use locally available materials and aggregates for base course and HMA, including recycled aggregates, complying with WisDOT specifications.

Asphalt Binder Grading: Penetration grade 120-150 or Viscosity grade AC 5.

Select above for normal parking lot ,below for high speed roads or large parking lot, or revise to suit project. See WAPA Design Guide. Performance grading will be used in the future.
Asphalt Binder Grading: Penetration grade 85-100 or Viscosity grade AC 10.

2.02 DESIGN MIX

Provide HMA design mix meeting WisDOT standards.

Select WisDOT HMA pavement type; see WAPA Design Guide. Type LV would be used for most residential or light commercial jobs. Delete others.
Pavement Type LV.
Pavement Type MV.
Pavement Type HV.

Aggregate gradation No. 3 is the default grade in WisDOT. If an especially smooth finish is desired (+$), use Grade No. 4 for surface course.
Aggregate Gradation No. 3.
Aggregate Gradation No. 4.


PART 3 — EXECUTION

3.01 SURFACE PREPARATION

Remove loose material from compacted base. Do not begin paving work until satisfactory base conditions have been corrected.

3.02 PAVING

Provide adequate trucks and equipment to assure a continuous paving operation, avoiding frequent delays. Once paving has started complete the project as soon as possible.

For a smooth, well-draining lot application in two lifts is recommended (+$). One lift application will follow contours of gravel base. Otherwise modify.
Place mixture in two lifts of 2" minimum thickness each at not less than 225ºF (107ºC). Spread and strike off. Place each course to required grade, cross section, and compacted thickness.

Provide joints between old and new pavements, other surfaces which will contact paving, and between successive days work for continuous bond between adjoining work. Clean contact surfaces just ahead of paving and apply tack coat.

Protect excess material from contamination and return to production for reheating and/or reuse [on-site for walkways][ditch beds][speed bumps][curbs].

Construct curbs over compacted pavement surfaces to cross section shown or, if not shown, to local standard shapes.

3.03 ROLLING

Begin rolling when mixture will bear roller weight without excessive displacement. Repair surface defects with hot material as rolling progresses. Cut out and patch defective areas and roll to blend with adjacent satisfactory paving. Continue rolling until maximum density attained and roller marks eliminated.

Protect paving from damage and vehicular traffic until mixture has cooled and attained its maximum degree of hardness.

3.04 TRAFFIC AND LANE MARKINGS

Apply 2 coats of chlorinated rubber type traffic lane marking paint over cleaned paving surface. Layout area and review with Architect before paint application. Use white color, unless otherwise directed.

Delete above if no markings.
