Field study on thermal behavior of lightweight cellular concrete as pavement subgrade protection in cold regions

Extremely low temperatures and freeze-thaw cycles cause premature cracking and low pavement bearing capacity. However, insulation layers could influence the extent of the temperature on pavements. This study focused on understanding the thermal behavior of lightweight cellular concrete (LCC) as an insulating subbase layer to protect the subgrade in pavements. The thermal performance was compared to a Control with Canada's conventional unbound …
