TIRED TYRES SUPPORT CAR PARK. WORN TYRES USED IN CONSTRUCTION OF A CRIB WALL

Details are given of a crib wall 40 M long and 3.7 M high constructed to form a flat car-parking area at West Yorkshire county council's workshops. The unusual construction detail of the wall concerns the use of some 4000 worn tyres, which were laid by five men and two machines at a rate of up to 360 tyres per 8 hr day. First, a layer of tyres was placed to give maximum interlock with the previous layer, using link bars where necessary. Then a crawler loader placed shale and siltstone fill over the tyres, and men shovelled the fill into the tyres. Finally a bomag vibrating roller compacted and levelled the fill. The sequence was repeated for each layer of tyres. The cost was approximately found21.60 per square metre of retained fill. Settlement was about 100 mm horizontally and vertically, and took place within ten weeks of completion. The crib wall depends for its strength on the tyres pressing and deforming around each other to hold the contained soil in an integral mass. Further developments lie in improved methods of filling the tyres, which at present is labour intensive, taking up over 80 per cent of the construction time. /TRRL/
