| 摘 要： | 根据实验资料,充分考虑级配碎石层的材料性质,建立了具有级配碎石基层的半刚性沥青路面结构的三维计算模型。分析表明:塑性突出的级配碎石层能优先于沥青面层和半刚性基层吸收路面结构在荷载作用下产生的应变能,从而提高了结构的抗裂及抗疲劳性能;级配碎石层能显著改善路面结构的力学性质,合理的设计能改善路面的使用性能,延长其使用寿命。

| Abstract: | Based on the experimental data,considering fully the material characteristic of grading macadam,the authors established a three-dimensional calculational model to semi-rigid asphalt pavement with grading macadam base.It is concluded that the grading macadam base with prominent plasticity takes precedence of semi-rigid subbase and asphalt course in absorbing the strain energy of the pavement under load,so can improve the performance of anti-cracking and anti-fatigue,and that the grading macadam base can prominently change the mechanical property of the pavement,and rational design can improve the pavement in performance and lifetime. |

| Keywords: | flexible base grading macadam reflecting crack elastoplasticity |
