Concrete paving in near-zero weather
Laying 1 1/2 million sq yd of concrete runways for large airport; usual cold weather methods were supplemented by heated mixer drums, insulated truck tanks, calcium chloride in mix and sand or straw covering to prevent subgrade from freezing; 12-in. straw blanket under heavy paper protected paved surfaces until concrete was safe from freezing; concrete was placed safely at 7 F while nights were as cold as 9 F below zero.
