<br />,., <br /> <br />. <br /> <br />.., <br /> <br />r-, <br />. <br /> <br />200-6.2 Moisture Content: When the material does not have the proper moisture <br />content to ensure the required density, wet or dry it as required. When adding water, <br />uniformly mix it in to the full depth of the course that is being compacted. During wetting <br />or drying operations, manipulate, as a unit, the entire width and depth of the course that is <br />being compacted. <br />200-6.3 Thickness Requirements: Within the entire limits of the length and width of <br />the finished base, meet the specified plan thickness in accordance with the requirements of <br />200-7.3.1.2. <br />200-6.4 Correction of Defects: <br />200-6.4.1 Contamination of Base Material: If, at any time, the subgrade <br />material becomes mixed with the base course material, dig out and remove the mixture, <br />and reshape and compact the subgrade. Then replace the materials removed with clean <br />base material, and shape and compact as specified above. Perform this work at no expense <br />to the Department. <br />200-6.4.2 Cracks and Checks: If cracks or checks appear in the base, either <br />before or after priming, which, in the opinion of the Engineer, would impair the structural <br />efficiency of the base, remove the cracks or checks by rescarifying, reshaping, adding base <br />material where necessary, and recompacting. <br />200-6.5 Compaction of Widening Strips: Where base construction consists of <br />widening strips and the trench width is not sufficient to permit use of standard base <br />compaction equipment, compact the base using vibratory compactors, trench rollers or <br />other special equipment which will achieve the density requirements specified herein. <br />When multiple course base construction is required, compact each course <br />prior to spreading material for the overlaying course. <br /> <br />. <br /> <br />., <br />. <br /> <br />., <br />. <br /> <br />I <br />I <br /> <br />f'l <br />. <br /> <br />I <br />I <br /> <br />ARTICLE 200-7 (Pages 195-198) is deleted and the following substituted: <br /> <br />..., <br />. <br /> <br />" <br /> <br />200-7 Acceptance Program. <br />200-7.1 General Requirements: Meet the requirements of 120-10.1, except use <br />200-7.2 instead of 120-10.2. <br />200-7.2 Acceptance Criteria: <br />200-7.2.1 Density: Within the entire limits of the width and depth of the <br />base, obtain a minimum density in any LOT of 98% of modified Proctor maximum density <br />as determined by AASHTO FM 1-T 180, Method D. Compact the base of any LOT of <br />shoulder pavement to not less than 95 % of the modified Proctor maximum density as <br />determined by FM 1-T 180, Method D. <br />200-7.2.2 Frequency: Conduct QC sampling and testing at a minimum <br />frequency listed in the table below. The Engineer will perform Verification sampling and <br />tests at a minimum frequency listed in the table below. <br /> <br />. <br /> <br />...., <br />. <br /> <br />r"1 <br />. <br /> <br />.., <br />. <br /> <br />., <br />. <br /> <br />r, <br /> <br />. <br /> <br />,.., <br /> <br />. <br /> <br />,.., <br /> <br />09/09 <br /> <br />01000-41 <br /> <br />03-4122.F <br /> <br />. <br />
