Roadway Base Rock Sizing
Roadway Base Rock Sizing
(OP)
Anyone have any thoughts on using 1 1/4"-0 base rock under ashphalt instead of 3/4"-0? Both compact very well. I have seen 1 1/4" used often but always with a 2" leveling course which I really dont think is needed.

Another is the shear strength of the mixture, affecting load transfer down to the subgrade. Of course we could go on as with soundness and frost heave effects, etc.
Be prepared for several different viewpoints.
