501.42 COMPACTION Each Pavement Layer shall be compacted to the Characteristic Dry Density General Ratio shown in Annexure 501A or greater. The Characteristic Dry Density shall be determined in accordance with Characteristic Dry Specification 201 QUALITY SYSTEMS ANNEXURE 201A 1.2.1. Density the pavement material contains more than 20% by mass of material Oversize Material retained on a 37.5mm sieve, the Maximum Dry Density shall be determined on that portion of the material that passes a 37.5mm sieve. 501.43 DRYBACK Each Pavement and the layer 150mm below the Subgrade shall be General dried back such that the Dryback Characteristic Moisture Content (DMc) is equal to or less than the proportion of the Optimum Moisture Content as shown in Annexure 501A as determined by Test Method WA 133.1 or WA 133.2 as appropriate. The Dryback Characteristic Moisture Content be determined in Dryback accordance with Specification 201 QUALITY SYSTEMS ANNEXURE 201A Characteristic 1.3. Moisture Content Where the pavement material or the material in the layer 150mm below the Oversize Material Subgrade contains more than 20% by mass of material retained on a 37.5mm sieve, the Optimum Moisture Content and the Maximum Dry Density shall be determined on that portion of the material that passes a 37.5mm sieve. 501.44 LAYER WIDTH The outer top edge of any layer of the pavement shall be no closer to the road centreline and no more than 100mm further away from the road centreline than the positions shown in the drawings. 501.45 SURFACE SHAPE 501.45.01 SUB-BASE The shape of the Sub-Base in granular Pavement shall be judged to be Max Deviation acceptable when the maximum deviation from a 3 metre straight edge 10mm placed in any position on the surface does not exceed 10mm. The shape of the Sub-Base under Full Depth Asphalt shall be judged to be Max Deviation acceptable when the maximum deviation from a 3 metre straight edge 15mm placed in any position on the surface does not exceed 15mm. Additionally, for pavement widening work, the crossfall at any position on Widening the new surface measured at right angles to the centreline shall be within 0.5% of the existing crossfall on the outer 2 metres of the adjacent traffic lane at that location. 501.45.02 BASECOURSE
