【摘要】 通过对弯沉指标分布规律的分析,确定了指标的概率模型和概率模型分析方法,并将其应用于国道312线凤翔路口—嵋岘段公路罗汉洞长坡段SBS改性沥青路面弯沉指标变异性分析中,得出半刚性基层改性沥青路面的动弯沉符合对数正态分布,而不符合正态分布概率函数的结论。更多还原

【Abstract】 Through the analysis of deflection index distribution law,it makes the probability model and probability model analysis method,and applies it into the variability analysis of SBS modified asphalt pavement deflection index of the section of the national way 312 from Fengxianglukou to Luohandong long slope road section of Meixian section,gets the conclusion that the dynamic deflection of semi-rigid base modified asphalt pavement complies with logarithmic normal distribution but does not comply with normal distribution probability functions.更多还原
