10.         PAVEMENT

10.1.       GENERAL SPECIFICATIONS
Each different pavement type is to have a uniform finish and colour. The pavement is to be constructed true
to the documented line and levels without local irregularities. There is to be no more than 2mm difference in
height between adjoining pavement segments or other adjoining pavements or tops of kerbs or pit covers.

Drainage
Ensure positive drainage to the kerb and drainage inlet grates to prevent ponding. Grout for direct bond
granite to be water repelled. Ensure there is less than 5mm deep water ponding 15 minutes after rain has
stopped,

Falls are to be achieved in the base slab or topping slab not via variations in the depth of the mortar bed or
sand bed.

Ensure a 1:10 threshold ramp is maintained at every known door (refer to grading plans). At retail facades
the 20mm level difference is subject to interior fit out.

Ensure positive drainage to the kerb and drainage inlet grates to prevent ponding.

Slip resistance
Ensure pavement finishes including sealers, tactiles and directional pavers are compliant with the slip
resistance requirements of the National Construction Code (NCC) and Australian Standards AS/NZS 4586
2013, AS HB 198 2014.

Ramp surfaces must have a slip resistance classification of minimum R11 rating for the oil-wet ramp test as
per Table 5 of AS / NZS 4586-2013.

Provide complying slip resistance test results to the Project Manager.

Solar Reflectance Index (SRI)
Pavements must achieve an SRI of >39 to achieve Green Star Compliance for Heat Island Effect Reduction.
Provide data sheets detailing SRI rating for any colour or material substitutions.
