with regards to asphalt, it is all in the polymers and "the mix." I worked with an event in Miami where the best paving company was contracted to lay down asphalt in a temporary section of a race course. The asphalt was put down with months to cure. Sixty days from the event, the entire course was evaulated and the asphault was breaking apart. It could be pulled up with you bare hands. The event had to make a decision wether to pour concrete (at a huge expense) or hope a polymer would speed up the curing process and strenghten the surface. Due to the heat and poor surface prep by the contractor, the asphault never cured properly and with the clock ticking, we went with the polymer.
The combination of intense heat, high horsepower and high downforce race cars turned the treated asphalt section of the course into a slippery section that was reffered to as the "ice rink" throughout the weekend. Eventually the asphalt gave way. By the end of the day on Saturday, there was a six (6) inch gash in the braking and acceleration sections. We ended up having to pour quickcrete overnight to fill up the grooves.
In florida, asphalt is hit or miss. Bottom line; it comes down to budget. Is it worth spending the dough? I'll bet the airport job was BIG BUCKS!!!! They are investing in their future as a commercial enterprise by offering a primium service.
Moroso looks great. I saw it a few months ago at a drag event. there were a few karts running the circuit, but not open to the public.
I asked about the comfort level of moroso regarding a drift event being run on the karting circuit, because track operators get nervous when the word "drifting "is mentioned. The owner of the Primus track is notoriously anal about the track surface. He has kicked out veteran (over 20 yrs experience) kart racers for numerous absurdities. Quite frankly, I was surprised Primus allowed a drift event. Homestead was also extremely concerned about the impact of a drift event and issued a no standing burnout decree, but in the end they were pleased with the event.
Good luck with Moroso. Let me know if i can be of any assistance. I'm looking to host a drift event on the west coast of Florida. My partners and I have insurance and sponsors.
