I'm wondering if you compact the material after putting it down. I seems like it would make a really soft shoulder and would wash out easily if you don't pack it down pretty well.
Idea: how about a hydraulic widening arm for doing partial depth repairs to match the width of the area ground out for replacement? I worked in the asphalt field for many years. This would be a great time saver in lew of doing multiple passes. Thanks guys.
Alright I know nobody gonna believe me but my cousin who is 66yrs old actually invented the first shoulder machine it was in Kentucky and he never put a patten on it so a guy that was working with him he from Ohio started to take photos of it and went back to Ohio made one and pattened it and now he is a millionaire and it makes my cousin sick to his stomach every day but there's nothing he could do
