When was the last time Daytona International Speedway was repaved?

Question

Drivers are starting to complain about how rought the surface is becoming

Answer 1

it is paved once every 2 years, but is treated twice a year

Answer 2

In Sept '06, Ryan Newman said " Talladega needed repaving after 27 years, he wants Daytona to be left alone and continue the aging that started in 1979."  I find no info on repaving since then.  Drivers have been complaining for the last few years on how bumpy the track has become.
