I think I've found another surface.. it's acoustic underlayment for tile... one is cork, which is very grippy but not overly so... and the other is rubberized an looks and behaves just like asphalt...

the cork one (VC300) comes on 39-inch x 62-foot rolls... and the rubber one (Cerazorb Green) comes in 48-inch x 30-foot rolls and you could easily make an 8-foot x 15-foot racing surface that's just like asphalt by cutting the roll in half and laying the halves next to each other... and maybe the halves can be connected or bonded to each other to create a rollable surface...
