Aggregate Road
Aggregate Road
(OP)
Hi, for analysis of pavements, if I have the same subgrade and traffic parameters, can it be possible that an aggregate road (CBR=80)has a total lesser thickness than a flexible pavement (AC layer + base CBR 80 + subbase CBR 20)? I was expecting the opposite but my calculations indicate that the aggregate road is thinner than the flexible AC pavement. Any input will be appreciated. Thanks !

Per the FDOT pavement design manual:
Superpave layer coeff = 0.44
Limerock layer coeff = 0.18
