A paved area can be milled to remove a surface layer to reduce the level, then to reuse the material elsewhere in the project or recycle it. For this operation, you need to reduce the ground by a set amount rather than to a set level. Naturally, the ‘Reduce’ element is perfect for this, as it allows you to specify both the area and the depth you want to reduce it by.
