Read on www.eurodragster.com that Santa Pod Raceway in England is finally going to an all concrete track surface. They have the records for best runs on an all asphalt track. Article said the asphalt is on top of a 1943 WWII runway and that all of that will be taken out before the concrete is laid. Trying to think of tracks still in existence that were runways. Bakersfield comes to mind. Probably others still out there.
