中国与美国路面不平整状况的对比分析

Comparison of road roughness between China and the United States

对中国和美国200多条道路路面(其中中国72条,美国135条)的国际平整度指数IRI(InternationalRoughnessIndex)进行了计算对比分析,从分析的结果可知,中国路面不平整的状况要远远差于美国的状况.

In this paper, the calculation was made to compare the difference of international roughness index (IRI) for pavement between China and the United States. The pavements include Chinese 72 and American 135. The contrast analytic results show that road roughness condition in China is far worse than that in the United States.
