What are the rules for placing concrete in cold weather on Arkansas DOT projects?
Concrete placement in cold weather on Arkansas DOT projects requires: (1) No placement if air temp < 36°F (2°C) unless heating ingredients and enclosing concrete is approved [4,6]. (2) Minimum concrete placement temp: 50°F (10°C) [2,6]. (3) Protection methods: insulated forms, blankets, or heating to maintain adjacent concrete temp ≥50°F (10°C) for 7 days (or prevent freezing for non-bridge work) [2,6]. (4) Class B concrete: forms must stay 4+ days if temps ≤40°F (4°C), with insulated blankets on exposed surfaces [2]. (5) Frozen aggregates prohibited [2]. (6) Heating methods: dry heat/steam only (no direct flame); water ≤180°F (82°C) [2]. (7) Frozen/damaged concrete must be removed/replaced [2].
