Recycling urban building -site clay into sports hills, Port Adelaide BMX Track, South Australia
Values for this imported clay soil:
– Clay moulds well when wet so can build the hills and hollows
– Clay is tough, good surface for BMX as it holds its shape, when dry.
Challenges of this clay – and how it is managed
– Slippery when wet, – 1. the ‘easier’ track has a covering of dolomite to set it like concrete for use even when wet and 2. using more difficult tracks is banned when wet
– Use may break up the surface a little into dust – water is used to settle the dust
– Remote controlled vehicles using the track have skinny wheels which break up the track – so they are banned
– Rainwater runs off the track and may erode some of the steep slopes
– designed to flow the water down into drains as much as possible and clay is repaired as needed.
