Table 3.6 Tolerances on Earthworks<br />
Item<br />
Tolerance<br />
Field Dry Density<br />
- 0% + 5% of specified compaction<br />
Depth of each fill layer<br />
Within ±25 mm of maximum layer thickness<br />
Finished level of pavement subgrade As detailed in the pavement design.<br />
Finished level of reserves<br />
Within ±75 mm of design level<br />
Finished level of batters<br />
Within ±75 mm of design level<br />
Shape of pavement subgrade Longitudinal ±20 mm below a 3.0 m straightedge<br />
Transverse ± 40mm below a 3.0 m straightedge<br />
The shape of the finished surface shall deviate below a 3.0 m straightedge, measured between any<br />
two points, by not more than the tolerances specified above.<br />
3.4.6 Acceptance Criteria<br />
Where test results show that the level of compaction of filling material that has been achieved is<br />
below the level specified, the areas or volumes represented by the tests (as determined by the<br />
Superintendent) may be rejected. The Contractor is to replace any defective material and re-work or<br />
