Coordinate location of the control strip with the CO. Construct the control strip using material, lay-down, and rolling procedures intended for the entire project.

Cease production after construction of the control strip until the material and the control strip are evaluated and accepted by the CO. Repeat the control strip process until an acceptable control strip is produced.

Acceptable control strips may remain in place and will be accepted as a part of the completed surface treatment. Correct unacceptable control strips.

Use these start-up procedures when changing construction procedures, when resuming production after a termination of production due to unsatisfactory quality according to Subsection 106.04, or the beginning of a new construction season.

409.10 Application. Substitute the following in place of the ninth paragraph:

Roll the parking areas and turnouts within 2 hours from the curing of the surface. Roll the parking areas and turnouts with at least two full-coverage passes with the roller.

Aggregate Type(1)

Application Rate (lb/yd2)

Type II 17 - 22 Type III 25 - 30

(1) See Table 703-8 for aggregate gradations.

F-3c DIVISION 400

Project: WA NPS PP MORA 2019(1), Pavement Preservation Mt Rainier

Application rates are based upon the weight of dry aggregate in the mixture. Application rates are affected by the unit weight and gradation of the aggregate and the demand of the surface to which the micro surfacing is being applied.

Fog the surface with water in front of the spreader.

Provide the CO with a split certified shipping ticket for each separate emulsified asphalt shipment load prior to mixing and application.

Prior to starting application of micro surfacing, calibrate each mixing unit to be used on the project in accordance with ISSA A143 and in the presence of the CO or designated representative. Clean the spreader box prior to start of each work shift.

Blend the additives with the aggregate. Pre-wet the aggregate in the pugmill before mixing with the polymer-modified emulsified asphalt.

Mix the surfacing material a maximum of 4 minutes. Ensure the mix is of uniform consistency as it leaves the mixer and conforms to the approved JMF. Adjust mineral filler and polymer-modified emulsified asphalt content during construction when approved by the CO to adjust for variations in field conditions.

Carry sufficient mix in the spreader to completely cover the surface. Spread the mix with a spreader box. In areas not accessible to the spreader use hand squeegees to work the mix.

Maintain quality control documentation and make available to the CO upon request and at completion of daily work. At a minimum of 4 times daily calculate the percent emulsion content, aggregate spread rate, and yield of the mixture from the equipment computer display readings and report to the CO. Maintain a daily report and log sheet containing the following information:

(a) Micro surfacing emulsion used, tons;

(b) Aggregate used, tons;

(c) Water used in the mixture, gallons;

(d) Mineral filler used, lbs;

(e) Set control agent used, gallons;

(f) Other additives used, lbs;

(g) Surface area application rate (dry lbs per square yard); and

(h) Percent of emulsion (by dry aggregate weight).

Provide copies of the daily log to the CO before the start of the next day’s production, or as directed by the CO.

Provide straight lines along curbs and shoulders and do not allow runoff onto these areas. Provide straight and neat starting and ending joints by masking surfaces at the start, end, and other locations as directed by the CO.

F-3d DIVISION 400

Project: WA NPS PP MORA 2019(1), Pavement Preservation Mt Rainier

For transverse joints, use a butt joint. Use building paper placed over previously placed micro surfacing or other suitable method to avoid double placement of micro surfacing. Remove ridges or bumps in the finished surface.

For longitudinal joints, place joints on lane lines. Use half passes and odd-width passes only in turnouts and parking areas. Do not use half passes for the last pass in paved areas. Overlap longitudinal joints no more than 3 inches (75 millimeters). Limit the elevation difference at joints to less than ¼ inch (6 millimeters).

Begin rolling after the mixture has cured to the point where it will not pick up on the roller tires.

Unless otherwise stated, do not open an area to traffic until rolling in that area is completed. Roll all areas with at least two full-coverage passes with the roller unless otherwise approved by the

CO.

Allow treated areas to cure completely before opening to traffic. Cure is complete when clear water can be pressed out of the placed mix with a piece of paper without discoloring the paper.

Remove streaks and transverse ripples as defined by ISSA A143 from the finished surface. Ensure the finished micro surfacing has a uniform texture free of scratches, tear, and other surface irregularities. Repair areas with surface irregularities or where the micro surfacing does not conform to the job-mix-formula at the direction of the CO.

Remove and dispose of material spills and associated debris at the end of each shift according to Subsections 203.05(a) and (d).

Perform an initial vacuum sweep of the micro surfacing one to two days after the micro surfacing application. Remove loose or shedding material from the treated surface areas. Salvage aggregate material from vacuum sweeping according to Subsection 203.03 and stockpile at the Park maintenance yard as directed by the CO.

Two weeks to one month after completion of micro surfacing application, before second application of paint, sweep the entire treated surface. Salvage aggregate material from vacuum sweeping according to Subsection 203.03 and stockpile at the Park maintenance yard as directed by the CO.

409.11 Acceptance. See Table 409-2 for sampling, testing, and acceptance requirements.

Polymer-modified emulsified asphalt will be evaluated under Subsections 106.03 and 106.04.

Furnish a production certification with each load of polymer-modified emulsified asphalt.

Micro surfacing aggregate will be evaluated under Subsections 106.02 and 106.04.

Mineral filler will be evaluated under Subsections 106.02 and 106.03.

Construction of the micro surfacing will be evaluated under Subsections 106.02 and 106.04.
