I am testing a well graded sand. Normally it's CBR value varies from 15% - 40% when tested. However the contractor with who I work always achieves above 30%. Including values of near the 70%. It's rare that sand achieves such high CBR values.
But lately the contractor only sends CBR values at 0.1". Gauge readings stops at 3.81mm or 4.45mm penetration.
Can anyone tell me what this means or can be the cause of this?
