Looks ok mate, though , and I know I will catch hell for this,,,, you might want to find an old sprayer and a couple of gallons of diesel and spray the asphalt then run over it a few time and spray again and run over,again and again,,, the diesel will make the asphalt soft and gooey and as the diesel evaporates the stuff will set up hard again,,, at least that's how I have seen it done round this part of the coal country
