1. Excavate to design depth.
2. Construct appropriate edge restraints.
3. Prepare and compact base course. Recommended material: 5-20 mm low fines crushed rock preferably basalt or equivalent. Compact in layers to design depth (normally 100-150 mm).
4. Cover base course with nonwoven geotextile (hydraulic conductivity min. 3600 mm/hr eg Geofirma 200B, Bidim A24 or equivalent).
5. Spread low fines bedding material (normally sand) to a uniform depth over unwoven geotextile, working no more than 1-2 metres ahead of laid paving units. See recommended particle size distribution of sand in Design section. Photos here show aggregate and sand being used as bedding materials. Recycled glass sand may be an option in certain applications. Allow 5-10 mm above finish level for settling after surface compaction.
6. Compact to depth of 30 mm: 3-5 passes at 30-40 metres per minute. With vehicle pavements, a plate compactor having the following capacity should be used: minimum plate area of 0.25 m2; minimum effective force per unit of plate of 75 kN/m2; frequency of 65-100 Hz; and minimum mass of 200kg.
7. Level and adjust depth of bedding layer.
8. Immediately after screeding, lay main body of area with HydroCERA permeable pavers. Use a mechanical device to cleanly cut pavers. Adjust surface levels of laid pavers with rubber hammer.
9. Adjust joints.
10. Brush in joint filler until all joints are completely filled. See recommended particle size distribution of joint filler (dry sand) in Design section.
11. Compact pavement with rubber plated compactor: 3-5 times at 30-40 metres per minute. Add joint filler as required to fully fill joints then compact again.
12. Brush off surplus joint filler.
13. Check paving unit levels and lines. Adjust surface levels with rubber hammer.
14. Remove all materials from site.
Note: as indicated in Step 2, pavements should have strong and appropriately designed edge restraints. Edge restraints were not constructed for the demonstration site photographed here.
