Is it a case of brilliant design and cheap construction, or is the terrain 'incompetent' as soil engineers say?
The track surface was ground recently, ahead of the MotoGP event, after complaints from MotoGP last year. I would think a lot of the debris that's being complained about was caused by the grinding.
In some quarters the problem is blamed on F1. The suggestion is that the high down force of F1 cars creates ripples in the tarmac.
Texas soils have high clay and sulfate mineral (typically, gypsum)
content, are expansive and make very poor foundation material.
Typically, ionic stabilizers such as lime are worked into them in order
to reduce the swell potential of active swelling clay soils. Left
untreated, active swelling clays cause heaving, distress and cracking in
foundations, concrete floor slabs, roads, highways, railways, etc..
They're just grinding the tops off the heaving. COTA will keep on
heaving until the track foundation is properly treated and repaved.
