| Abstract: | In order to study the influence of subgrade thawing settlement deformation on the mechanical properties of flexible pavement in permafrost region,two thawing settlement deformation simulation methods of frozen soil subgrade,i.e.loose paving soil and burying industrial ice block,were adopted.Laboratory large-scale experiment tank of flexible pavement structure was built and transducers were buried layer by layer.The stress and strain detection of flexible pavement surface course and base course were carried ... |
