摘要
通过引入波形函数对行驶质量中级及以上的沥青路面进行模拟,分析连续式平整度仪的测量原理,借由数据统计方法得出由计算区间的值估算检测路段平整度值的方法;通过分析国际平整度指数与路面行驶质量指数和连续式平整度仪标准差的关系,得出行驶质量指数与连续式平整度仪标准差之间的标定关系,由此得出沥青路面需要养护、维修和改建的平整度临界值。
Through using the wave function, asphalt pavement with driving quality intermediate and above was simulated. The measuring principle of continuous - measuring ins - trument for roughness was analyzed. Then, a fast esti - mate method of detested section roughness by the value of calculated extent was obtained based on statistical methods. Furthermore, through the relationship between international roughness index and driving quality index, this paper found out a new demarcation approach for measuring driving quality index through using the standard deviation of roughness index. By following this approach, it finally achieves the roughness threshold of asphalt pavement for maintenance, repair and recons -truction.
