3.09 Compaction Requirements <br />I' . <br />1 <br />A. All embankment fill material (Type 1 and Type 2) shall be compacted to at <br />least 95% of Standard Proctor Density (AASHTO T-99), ASTM D-&98) at a • <br />moisture content 2% below to 2% above optimum moisture. Material <br />adjacent to natural material shall be compacted to 100% of the Standard <br />Proctor Density. <br />B. All structural bedding material shall be compacted to 100% of Standard <br />Proctor Density. <br />II <br />(- <br />1r <br />I <br />i <br />~._ <br />C. All general backfill materiel shall be compacted to 90% of Standard Proctor <br />Density. <br />3.10 Tolerances <br />Grading of cut and fill areas of channels, embankments, foundations, etc., shall <br />conform to the following tolerances: <br />A. A vertical tolerance of zero above and 0.1 feet below the specified grade <br />will be allowed on the pipe bottom; however, the invert must be graded to be <br />flowing at all locations and no standing water will be allowed. <br />B. Structural excavation shall be true to grade. <br />C. Roadways shall have a vertical tolerance of 0.1 feet above or below the <br />specified grade. <br />D. Foundation excavation shall have a vertical tolerance of zero above and 0.3 <br />feet below the specified elevation <br />E. Embankment fill areas shall have a vertical tolerance of zero below and 0.2 <br />feet above the specified elevation for the post construction condition. <br />F. Horizontal tolerance for all earthwork shall be less than 0.5 feet from the <br />design line as shown on the Drawings. <br />G. Horizontal alignment for all pipes, structures and drains shall be the design <br />line. <br />.._ <br />i <br />I <br />I <br />L <br />H. Regardless of the construction tolerances specified, the excavation and <br />grading shall be performed in such a manner that the finished surfaces are in <br />uniform planes with no abrupt breaks in the surface and the adjacent ground <br />is free draining. <br />The construction tolerances specified herein for grading are solely for <br />purposes of field control <br />02200-11 <br />• <br /> <br />
