Abstract : Field investigations were made at five airfields, with varying subsurface conditions, located in the northern part of the United States and laboratory studies were conducted at the Frost Effects Laboratory. The purpose of the investigations was to augment the tests made and data obtained from the frost investigations conducted during the years 1944 to 1946 inclusive. The report with the appendices presents the data obtained during the fiscal year 1946-1947 with the conclusions based on these studies. On the basis of these studies, a change in the design curves for rigid pavements is recommended which would decrease the required thickness of concrete for the 60,000 and 150,000 pound wheel load designs by one inch in most cases.
