This is on private property, and the total length of the walkway will be about 20 feet. I don’t want a curb, and I want the concrete to be at the same level as the blacktop for ease of snow-plowing.
Trouble is, the edge of the blacktop is not square; it’s a soft curve that fades into the ground (see above). If I dig out the soil next to the blacktop, put down a bed of gravel and pour concrete right up to the blacktop, the concrete will have a feather edge onto the blacktop which will soon flake off, leaving an ugly furrow. How should I deal with this?
My first thought is to take my worm-drive circular saw with a 7-1/4” abrasive blade for masonry and cut a square edge on the blacktop as deep as the blade will go. (I don’t have a pavement cutter.) I’ll finish the joint between the blacktop and concrete with a concrete edging tool.
Is there a better / easier way to make the transition from the soft edge of the blacktop to the concrete without renting a pavement cutter?
