California bearing ratio Wikipedia
A CBR of 3 equates to tilled farmland, a CBR of equates to turf or moist clay, while moist sand may have a CBR of 10. High quality crushed rock has a CBR over 80. The standard material for this test is crushed California limestone which has a value of 100, meaning that it is not unusual to see CBR values of over 100 in wellcompacted areas.
