Special Contract Requirements Project: MT BOR NPS 2021(1), Yellowtail Dam Area Road Improvements

Repeat the control strip process until an acceptable control strip is produced. Cease production until the material and the control strip are evaluated and accepted. The CO will indicate which strip will serve as the accepted project control strip.

Accepted control strips may remain in place and will be accepted as a part of the completed project. Correct rejected control strips.

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

407.10 Aggregate Application. Delete this Subsection and substitute the following:

If emulsified asphalt is used, verify the aggregate stockpile moisture daily and use moist surfaced aggregate.

If asphalt binder is used, dry the aggregate. Precoat the aggregate uniformly with 2 to 3 percent of residual asphalt by mass of aggregate. Maintain the flow qualities of the precoated aggregate to allow uniform spreading with the aggregate spreader.

Calibrate aggregate spreaders before the start of project and if directed. Calibrate the longitudinal and transverse spread rates.

Apply aggregate uniformly at the optimum application rate determined from the accepted control strip. Apply the aggregate immediately after the asphalt material is applied. Operate the aggregate spreader so asphalt is covered with the aggregate before wheels pass over it. For part-width construction, leave an uncovered 6-inch wide asphalt strip to allow an overlap of asphalt material.

Cover excess asphalt with blotter.

Correct excesses and deficiencies by adding or removing aggregate to achieve a uniform texture before the asphalt cures.

Operate rollers at a maximum speed of 5 miles per hour. Do not allow the aggregate to be displaced by pickup or sticking of material to the tire surface. Roll the surface to bond the aggregate uniformly and thoroughly over the full width. Complete rolling within 1 hour after asphalt is applied to the surface. Perform three passes with the rollers. Do not allow traffic to travel over aggregate until rolling is completed and if used, the fog seal has cured.

Submit documentation for calibrations and application rates at the end of each day’s production.

Use a pilot car according to Section 635 to limit traffic speeds to 10 miles per hour for at least the first 45 minutes after rolling. Limit speeds to 20 miles per hour for the next 24 hours.

Vacuum sweep the surface to remove excess aggregate when the air temperature is below 90 °F.

Do not displace embedded material. Lightly vacuum sweep the roadway surface within 24 hours of aggregate application. Vacuum sweep the roadway surface within 48 hours after aggregate application to remove excess aggregate from the roadway surface unless otherwise approved. Hand broom in select locations to remove excess aggregate if directed. Dispose of material removed excess aggregate according to Subsection 203.06 203.05 (a) and (b).
