What air content is required for concrete on Idaho DOT projects?

"Air content, percent of plastic mix 0 - 6.5" [2] "Test for slump, unit weight, air content, and compressive strength for acceptance." [3] "Table 509.01- 3 – Pay Factor Adjustment for Air Content Above or Below Specified Air Content Pay Factor Less than 0.25% 0.99 0.50 to 0.25% to 0.50% 0.90 Above 0.50% Subject to rejection" [3] "If allowed to remain in place, as determined by the Engineer, the pay factor will be 0.50." [3] "Air Content Percent 65 and greater, Self consolidated concrete (d)(e)(f)(g) 660 NA 0.42 0- 6.0 45 to less than 65 (d)(e)(f)(g) 560 710 0.44 0- 6.0 35 to less than 45 (d)(e)(f)(g) 470 615 0.44 0- 6.0 30 470 570 0.50 6.5±1.5 Seal Concrete 660 N/A 0.60 0 - 6.0 Mass Concrete (d)(e)(g)(h) 560 N/A 0.44 0- 6.0" [5] "Concrete designated as Class A will have an air content of 6.5 plus or minus 1.5 percent." [5] "Concrete designated as Class C will have a maximum water cement ratio of 0.40, water reducer required, and air content of 6.5 plus or minus 1.5 percent." [5]
