cbr value for base course in roadworks soil testing

CBR value for base-course in roadworks - Soil testing ...

2006-11-16  I would suggest a value in excess of 100% would be easily achievable. As for it being unsoaked, there is little point soaking non-cohesive material anyway. RE: CBR value for base-course in roadworks. Ron (Structural) 11 Nov 06 16:54. Emilian...yes, a CBR can exceed 100, particularly in an unsoaked condition.
