气象条件对高速公路路面抗滑性能影响的试验

对高速公路路面抗滑性能与温度、路面状况及使用融雪剂等不同条件的关系进行测试和分析,测试在实验室条件下和实际路面上分别进行。测试及分析结果表明:路面抗滑性能因气温和路面状况不同而有很大差异,尤其是冬季的冰雪和低温天气,对路面抗滑性能的不利影响最为显著。此外,气象条件与路面实际抗滑性能的关系还与其标准抗滑性能有关。

Influence of Weather Conditions on Highway Antiskid Performance

The antiskid performance of highways was tested both in the laboratory and on the highway.The relationship between highway antiskid performance and temperature,as well as the state of the pavements,is studied.The results indicate that the antiskid performance of the pavements varies with the changing temperature or state of the pavements;there is a notable negative effect on antiskid performance at low temperature and in ice and snow weather in winter;the influence of meteorological conditions is related to the standard antiskid performance of highways.
