Nettet1. jul. 2011 · It is almost identical to the CBR, just with a slightly different scaling. The CBR is typically 80 percent of the LBR in value, so a material with a CBR of 80 would have an LBR of 100. We routinely see values (equivalent CBR) in the range of 130 to 200 for crushed limerock base and crushed concrete base.
