4.1 Gravel Pavements

4.1.1 Materials

Pavement materials shall be of uniform approved quality and may be rejected if they contain quantities of
earth, clay or vegetable matter that, in the opinion of the Superintendent, render them unsuitable.

The quality and thickness shown or ordered for each course shall be the minimum allowable thickness
for that particular course.

Pavement materials shall conform to the Local Council specification requirements as follows:

Base Queensland Department of Main Roads Type 2.1
Sub base Queensland Department of Main Roads Type 2.3

The Contractor shall submit test certificates for the paving materials he proposes to use and the
materials shall be approved by the Superintendent before paving is commenced.

4.1.2 Compaction of Pavements

Paving materials shall be compacted at a suitable moisture content to a density that shall be not less
than 100% relative dry density (standard compaction).

Rolling shall start at the edges and finish at the centre of the pavement and successive passes shall
overlap. Rolling of each layer shall continue until the specified compaction is obtained.

Paving shall be compacted in layers of not less than 75mm and not more than 200mm compacted
thickness.

After compaction of the pavement the whole of the surface shall be watered then rolled with a steel
wheel roller to give a hard, dense, tightly locked, stone mosaic surface that is free of lenses, compaction
planes and caking.

For pavement, the following geometric tolerances will apply:
