cement treated permeable base as a wearing course?

I have a project where they want to construct a fire access road around the complex using pavers over permeable base. During construction they want to use the road for construction vehicles (without the pavers). I suggested using cement treated permeable base (it's 3 sack with all coarse aggregate 1" minus very little fines compacted with a smooth drum roller, no vibration) with 5 mph speed limits. I've done the pavers over CTPB before and it works great. Does anyone have any experience with haul roads using CTPB or CTB?

thanks
