I can look into some of my notes from when dealing with the asphalt company but 5-10 % oil is a must and the finest grade sand as well. Those are the 2 biggest qualities that give you long lasting great traction, in the beginning tire wear is high but will get better. Your main concern is long term virtually maintenance free care by that I mean less cracks and asphalt maintenance as possible.
Tennis court grades are usually a bit more pricey but longer lasting.
