Good Morning, I'm in the tail end of a walkway installation that runs perpendicular to an asphalt driveway. I cut into the asphalt slightly inward, i compacted the heck out of my base, and i have just enough fabric to lap up against the asphalt base. So now, i haven't polysanded in the pavers and, i have this void between where the final pavers lay and the asphalt. My measurements & cut, could have been (alot) better.. What would you guys use suggest i use to fill the gap, that at its start is about 1/2 inch and ends somewhere at about 1 1/2 inch? I've got a couple ideas, but i'm hoping someone with more experience has a better solution.
