Seasonal and Spatial Variation of Subgrade Response
, 2000 Temperature, subgrade moisture content, and Falling Weight Defleetometer (FWD)-deflection data were collected monthly on four asphalt pavement test sections in Kansas for a year. The subgrade moduli were baekealeulated using the elastic layer theory.

On the Moisture Condition of Highway Subgrade [PDF]
, 1960 We cannot design a reliable highway pavement without knowledge of the moisture condition of the paved subgrade because the bearing capacity of subgrade changes much with the moisture condition.

Study on Capillarity Water Rise in Subgrade Soil
, 2011 Many highways in China cross irrigation area of farm land. The water in rivers and ponds by two sides of roads can flush back into subgrade, and results in more water in subgrade soil, subgrade deformation and lowered capacity.
