Hello everyone,
I am currently renewing my driveway. So far, about 60 square meters (645 square feet) of old paving have been removed, and now new paving will be installed.
What I noticed is that there was sand beneath the old paving, and below that an extremely hard layer. I assume this is crushed stone (gravel) that was compacted very firmly about 40 years ago.
Unfortunately, this layer is uneven and not level in some places. Before spreading the 5 cm (2 inches) bedding layer of grit on top, I would like to have a smooth, level base layer. What do you recommend for this? I initially thought of adding more crushed stone, but I am concerned that I won’t be able to properly compact it into the existing base with a plate compactor. This layer is really hard, almost like concrete.
I was told that the bedding layer of grit should not be thicker than 5 cm (2 inches). But how can I best level out these uneven spots in the base layer to create a flat surface?
Thanks for your advice!

Do not remove any material (unless necessary due to elevation requirements).
