AC paving on a steep driveway
AC paving on a steep driveway
(OP)
I am working on a small residential project that will require re-working a bit of the driveway. Existing driveway is ac paved with a slope of about 19% and I'm concerned about vehicle grip. What is the best way to ensure good roughness on new AC? Is there any data supporting roughness anything close to brushed concrete?
Thanks in advance.

One factor is moving that paver up the slope. They may have to use supplemental towing of the paver. Compaction is likely to be light, but that may not be too bad, since fines will erode in time and leave a coarser surface. Here these slopes are working better than tight surface areas for traction, yet are not deteriorating.
If you can get what we call a binder mix, that is coarser, in time it will be better for icy conditions, etc., since coarse particles will dominate the surface.
Don't make the mistake of using a paint-type sealer,making it more slick.
