摘要
为了定量评价沥青路面抗滑表层抗滑效果及其抗滑性能衰减情况,结合室内试验已有研究成果,以集料体积(质量)分维数为自变量,路面抗滑性能长期评定指标(摆值、构造深度)为因变量,建立两者的关系模型,并结合分形理论进行分析,从而对沥青路面抗滑性能进行分形评价。研究结果表明:沥青路面抗滑性能分形评价方法的结果与室内试验结果一致。
In order to quantitatively evaluate the anti - skid effect and the attenuation of anti - skidperformance of anti-skid surface on asphalt pavement, the fractal dimension of aggregate （mass） was usedas the independent variable and long term evaluation indices （set value ＆ structural depth） for anti-skidperformance of pavement used as the dependent variable as combined with the research results of indoorexperiments to establish the model of relationship between the two variables. Then analysis was made incombination with fractal theory, so as to carry out fractal evaluation over the anti -skid performance ofasphalt pavement. The results show that the fractal evaluation for asphalt pavement anti-skid effect deliversthe same resultsas the indoor test.
