当前中国使用沥青路面的频率越越高,如何降低道路交通安全事故率成为一门学问,而路面抗滑性能是影响行车安全的主要因素。针对目前沥青路面抗滑性能检测评价中的不足,本文引入了数学中的分形理论对沥青路面的构造深度进行研究。通过分析比较,这种方法可以更真实地反映出路面的实际情况,丰富了路面抗滑性能的检测评价方法,有利于道路管理者更准确地作出养护决策保证路面的安全性能。
At present, the frequency of using asphalt pavement in China is higher and higher, and how to reduce the rate of road traffic accidents becomes a knowledge, and the anti-skid performance of pavement is the main factor that affects traffic safety. Aiming at the shortcomings of current asphalt pavement skid resistance testing and evaluation, this paper introduces the fractal theory in mathematics to study the structure depth of asphalt pavement. Through analysis and comparison, this method can more truly reflect the actual situation of the pavement and enrich the testing and evaluation methods of the pavement slip resistance, which is beneficial to the road managers to make more accurate maintenance decision to ensure the pavement safety performance.
