| Abstract: | In order to investigate the impact of ice-split on the propagation of the asphalt pavement surface cracking in the alternate freezing and thawing seasons,the pavement structure model was built by utilizing ABAQUS based on fracture mechanics.The variations of stress intensity factor under ice-split effect,thermal shrinkage effect and combination of both effects on pavement surface cracking were calculated.Besides,the effects of ponding depth in crack gap,crack width and crack length were evaluated.The Pearso... |
