10. MIXING

1. Mix the aggregate by any one of the three following methods.

0. Stationary Plant Method: Mix aggregate base course and appropriate amount of water for compaction in an approved mixer. After mixing, transport aggregate to the job site while it contains the proper moisture content and place on the roadbed with an approved aggregate spreader. Before compaction, remove excess moisture.

0. Travel Plant Method: After the material for each layer has been placed through an aggregate spreader or windrow sizing device, it shall be uniformly mixed by a traveling mixing plant.

0. Road Mix Method: After placing each layer, mix materials at optimum moisture content using motor graders or other approved equipment until the moisture is uniform throughout.

1. When commercial binders or fillers are used with aggregate, mix with a central mixing plant of the twinpugmill type. Other methods that ensure a thorough and homogenous mixture may be used on written approval.

10. COMPACTION

2. Compact each layer to a density of not less than 95 percent of the maximum density, as determined by AASHTO T18074, Method D. Contracting Officer will test density inplace, in accordance with AASHTO T19161, T20564, or other recognized method. Random tests for compacted depth will be made during the progress of the work.

10. SURFACE FINISHING

3. Use a smooth steel wheel roller for the final rolling of top surface base course. Water surface and evenly spread loose stones before final rolling. Make minimum of two complete passes over area to embed stones. Correct soft spots developed during rolling.

3. Compacted base course surface shall be smooth and free from waves and other irregularities. Unsatisfactory portions of base course shall be torn up, reworked, relaid, and rerolled, at no additional expense to the Government.

10. MATERIAL ACCEPTANCE REQUIREMENTS

4. Acceptance will be based on periodic samples and tests taken following mixing and before laying.

10. TOLERANCES

5. Surface: The Contracting Officer will test finished surface of the base course with a 10foot straightedge or other device. The variation between any two contacts with the surface shall not exceed 1/2 inch. Any areas not complying with these tolerances shall be reworked to obtain conformity.

5. Width: Plan dimension, plus or minus 2 inches.

5. Thickness: Plan dimension, plus or minus 1/2 inch.

10. MAINTENANCE

6. Maintain base course in a satisfactory condition until surfaced or until final acceptance.
