| 摘 要： | 文章采用美国KENPAVE软件对比分析了2种典型级配碎石基层路面结构在不同厚度条件下的路表弯沉、沥青层底拉应变、土基顶面压应变等力学指标,并采用灰关联法分析了各力学指标对结构影响的显著程度。研究表明:倒装路面结构形式优于柔性基层路面结构形式,且碎石夹层厚度为15cm左右时,结构形式最优。

| Abstract: | In this paper, mechanical indexes of two typical kinds of graded crushed stone base asphalt pavement structures are compared and analyzed under different thickness using an American software KENPAVE, such as surface deflection, tensile strain at the bottom of asphalt layer, compressive strain on the top of subgrade etc.. The impacting degree of all the indexes on pavement structure is analyzed using the grey relational analysis method. The results indicate that inverted pavement struc- ture is superior to flexible base pavement structure, and the structure is optimum when the thickness of granular interlayer is about 15 cm. |
