Compaction. Compact sub-grade to a minimum 90% and a maximum 95%. Over-compaction can inhibit subgrade percolation. Compaction shall be in accordance with ASTM D1557.
Compaction. The Contractor may employ other compaction equipment and methods in addition to the vibratory roller to accomplish the final grading and to compact and finish the surface. Transverse joints shall be compacted by cross-rolling parallel to the joint. After the material has been compacted to load-bearing strength, the Contractor shall proof-roll the prepared base in the presence of the Inspector. The Public Works/Engineering Department may, as it deems necessary, direct the Contractor to correct areas of weakness and excess moisture in the base by scarifying, aerating, and reworking shore sessions to the full depth of the layer. If, after an area has been reworked and recompacted, it remains soft or does not attain the required density, the Public Works/Engineering Department may direct the Contractor to remove the material and replace it with Granular Base Material meeting the requirements of these specifications. This material shall be counted for payment under the pay item for Excavation and Granular Base Material. BASIS OF PAYMENT
Compaction. The County recognizes that there is compaction between base pay of Unit F classifications and the base pay of line positions in the same class series. The County and the Union agree that compaction is an outstanding matter. The parties have met and compiled data and identified classifications that must be prioritized. The parties agree to meet no later than September 1, 2016 to update and collaborate on compaction for F Unit supervisors to address egregious classifications where compaction is less than five percent (5%). The parties agree that no recommendation shall include a rate less than the current compensation philosophy which shall be reviewed by the County. Upon evaluation of the data, it is the intent of the parties that all bargaining unit positions who supervise staff receiving competency, certification, modality, float, longevity, differential and bilingual pay shall receive at least an amount equal to that being paid to the staff supervised unless another amount is designated, if applicable.
Compaction. Structural fill shall be compacted by dozer track in lifts not to exceed eight (8) inches in depth, or by compactor in lifts not to exceed twelve (12) inches in depth. Compaction shall be equal to or greater than the natural state of the soil or a minimum of seventy (70) percent relative degree of compaction. Woody material shall not be deposited in fills.
Compaction. Compaction shall be carried out using suitable equipment or hand rammers. Earth shall be slightly moist at the time of compaction and compacted in layers not exceeding 200 mm thick where machinery is used and 100 mm thick where hand-held equipment is used. Granular fill shall be compacted to ensure that it has reached minimum volume. Filling around structures shall be carried out carefully to avoid damage.
Compaction. A. Compact materials at moisture content within +2% of the optimum to permit specified compaction.
Compaction. When the methods listed below specify compaction, Traveled Way shall be compacted by an 8 to 10 ton pneumatic, steel-wheeled or equivalent vibrating roller making 2 passes over the full Traveled Way and Shoulder width, unless compaction is not required on the Dust Abatement Plan (C5.31#). T-806-1 3.3 Preparation to Dust Abatement Materials Other Than Water. The following applies to all methods of preparation: Bituminous residue shall be scarified and pulverized to produce loosened Material not exceeding 4 inches in greatest dimension. Traveled Way shall be bladed in accordance with T-803. Prior to applying DO-6BA, DO-6PA, or DO-8, the top 2 inches of Traveled Way shall contain not less than 80 percent nor more than 120 percent of optimum moisture as determined by AASHTO T-99, Method C. Prior to applying other bituminous Material, Traveled Way shall have a moisture content between 1 and 3 percent. If surface dusting prevents the bituminous Material from penetrating, a light application of water shall be applied just prior to applying the bituminous Material. Lignin Sulfonate and magnesium chloride shall be applied when the top 1 inch of Traveled Way contains not less than 3 percent moisture, nor more than 120 percent of optimum moisture as determined by AASHTO T-99, Method C. Moisture content will be determined in accordance with AASHTO T-217 OR T-239. One or more of the following methods shall be used, as specified in the Dust Abatement Plan (C5.31#). Method 1. Compact Traveled Way and apply the dust abatement Material.
