3.02 MIXING <br /> A. Mix the aggregate by any one of the three following methods. i <br /> 1. Stationary Plant Method: Mix aggregate material and appropriate amount of water <br /> for compaction in an approved mixer. After mixing, transport aggregate to the job <br /> site while it contains the proper moisture content and place on the roadbed by , <br /> means of an approved aggregate spreader. Excess moisture in material at time of <br /> laydown shall be removed prior to compaction. <br /> B. Travel Plant Method: After the material for each layer has been placed through an aggregate ' <br /> spreader or windrow sizing device, it shall be uniformly mixed by a traveling mixing plant. <br /> C. Road Mix Method: After placing each layer, mix the materials while at optimum moisture <br /> content by means of motor graders or other approved equipment until the moisture is uniform <br /> throughout. ' <br /> 1. When materials are to be used that require the mixing of commercial binders or <br /> fillers with the aggregate, a central mixing plant of the two- pug mill type will be <br /> required. Other methods that assure a thorough and homogenous mixture may be <br /> used on written approval. <br /> 3.03 COMPACTION <br /> A. Continue compaction of each layer until a density of not less than 95 percent of the maximum , <br /> density as determined by ASTM D-1557-91 has been achieved. In-place field density <br /> determinations will be made by the Owner in accordance with ASTM D-1557-91 or other <br /> recognized method. Random tests 50 feet on center maximum along roadway for <br /> compacted depth will be made by the Soils Engineer during the progress of the work. <br /> 3.04 SURFACE FINISHING , <br /> A. Use a smooth steel wheel roller for the final rolling of top surface base course. Water <br /> surface and evenly spread loose stones prior to final rolling. Make minimum of two complete <br /> passes over area to embed stones. Correct soft spots developed during rolling. <br /> B. Compacted aggregate course surface shall be smooth and free from waves and other <br /> irregularities. Unsatisfactory portions of base course shall be torn up, reworked, relayed,and <br /> re-rolled, at no additional expense to the Owner. ' <br /> 3.05 ACCEPTANCE REQUIREMENTS <br /> A. Material shall be subject to acceptance as follows: ' <br /> Construction Method Time of Acceptance <br /> Stationary Plant Mixed Immediately following mixing ' <br /> Travel Plant Mixed After mixing and before laying <br /> Road Mixed After mixing; from combined ' <br /> window <br /> 3.06 TOLERANCES <br /> A. Untreated Base Course Surface: The Owner's Representative will test finished surface of the , <br /> base course with a 10-foot straightedge or other device prior to the application of primer or <br /> pavement. The variation between any two contacts with these tolerances shall be reworked <br /> to obtain conformity. Grading is set for very minimum grades. Contractor shall take extreme <br /> care to finalize all final grades to drain. <br /> B. Width: Plan dimension, plus or minus 2 inches. <br /> C. Thickness: Plan dimension, plus or minus 1/2 inch.
