| 摘要： | Pavement seal behaviors were investigated using the finite element method to obtain a better understanding of their failure mechanisms. This knowledge is needed to explain failures that actually occur in the field and may help to reduce joint seal costs, which are estimated to be $12M annually. The effects of width, depth, and size were evaluated and compared with parabolic predictions. The finite element results indicated that the assumption of a parabolic free surface upon expansion was not applicable in all cases and the strains were not uniform. The finite element results consistently showed high strains at the vertical pavement- joint seal interface, suggesting that failures should occur there first in properly designed joints. |
