What are the curing requirements for concrete pavement in Colorado?
For Colorado concrete pavement, apply ASTM C309 Type 2 VOC-compliant curing compound within 10 mins of final finish, using 1 gal/180 sq ft (initial + repeat in 30 mins) or 1 gal/120 sq ft (single application). Cover 100% of surface with automated sprayers; protect film for 72 hrs (longer if open to traffic). Cold weather (<40°F) requires maintaining pavement ≥40°F until 2000 psi strength via maturity meters [1][4].
