9.3.4 Unsealed Footpath Where the specified works interfere with existing unsealed footpath areas, or where footpaths are nominated on the drawings as unsealed, the reinstatement / construction shall consist of 100 mm compacted thickness of PM 2/20 quarry rubble. The rubble shall be placed and compacted to a density of not less than 95% of the maximum modified dry density as set out in AS 1289 5.2.1 using approved compaction equipment. The rubble shall be finished to conform to the adjacent existing paths in level and appearance and to give satisfactory drainage properties. The Contractor shall ensure that completed works are not hazardous or threaten in any way the safety of the general public. 9.3.5 Concrete Driveway Concrete footpaths shall be constructed to as detailed in the design drawings or to a minimum of 100 mm granular sub-base with 125 mm thickness concrete base, and reinforced with SL72 steel fabric. Reinforcement shall be free from loose mill scale, loose rust, oil, grease and other non-metallic coatings which would reduce the bond to the concrete. Bar chairs, spacers and ties made of concrete, steel or plastic shall be used to support all reinforcement in its position within the tolerance specified in AS 3600 until the concrete has hardened. Reinforcement shall be located in the upper half of the driveway slab with a minimum 40 mm top cover, and terminated 75 mm from 50 mm from joints. 9.3.5.1 Concrete Driveway Joints Expansion joints shall be 10 mm wide provided at minimum 12 m intervals. Expansion joints shall be provided with a full depth pre-moulded expansion joint filler, (bitumen impregnated fibre board or similar). In areas where new concrete is to be placed against and existing construction joint, the surface of the hardened concrete shall be thoroughly roughened and cleaned to remove any loose material, debris and laitance. 9.3.6 Grassing Following filling, spreading and levelling of topsoil, all exposed batter slopes, excavated and filled areas shall be reseeded. Fertiliser shall be applied to the areas to be grassed at the rate of 30 grams of 2:1 superphosphate and sulphate of ammonia or other approved fertiliser per square metre. The area shall then be raked, seed spread and lightly raked again. A seed mix containing couch and perennial rye grasses or an approved alternative mix, shall be spread at a rate of 30 grams per square metre and watered to ensure germination and growth during the establishment period. As an alternative method of application, hydromulching using a seed/fertiliser mix similar to that specified above may be used. 9.4 Quality Requirements – Verges, Footpaths and Verges 9.4.1 Tolerances The following tolerances shall apply to finished kerbing and footpaths: Table 9.1 Item Tolerances on Verges, Footpaths and Driveways Tolerance Ref No. 20120236SA1 Kingscote Streets Upgrades Technical Specification 43
Footpaths and driveways Absolute ±10mm Relative ±6 mm from a 1.0 m straight edge Alignment ±10 mm from design location Verges Level ±50mm 9.4.2 Acceptance Criteria Footpaths and driveways which are chipped, cracked, displaced or otherwise damaged during the construction of other works shall be removed and new sections shall be constructed to match existing work, to the satisfaction of the Superintendent.
