| Abstract: | In respect that flexible base (grading macada m) is applied to prevent semi-rigid asphalt pavement from reflecting cracking, the elastoplastic ity finite element method (FEM) was employed to analyze the maximum tensile stre ss change rules of surfacing course undersides and semi-rigid base undersides i n three kinds of test road pavements in Tonghua, Jilin, by considering the non- linear (elastoplastic) characteristics of the flexible base. Consequently, some reasonable suggestions for the design of semi-rigid asphalt pavement with granu lar base in Tonghua test road were brought forward, and the fatigue lives of sur facing courses of two semi-rigid asphalt pavements were forecasted as well. |
| Keywords: | grannular base flexible base elastoplasticity fati gue life |
