摘要
通过对铺装了导电体的自发热机场沥青混凝土道面进行化冰试验与融雪试验(初始温度为-10℃、导体控制温度为50℃、设置和不设置隔热层),得出了融雪化冰所需时间和设置隔热层能够提高能量利用率的结论。运用有限元软件融雪化冰分析,与试验结果对比,验证了试验结果的正确性。并对下一步研究工作提出了建议。
Through ice melting test and snow melting test on self-heating airport asphalt concrete pavement with conductor（initial temperature-10℃,conductor control temperature 50℃,with or without thermal-protective coating）,the necessary time for snow-ice melting is obtained and it is summarized that energy utilization ratio can be improved by setting thermal-protective coating.This paper analyzes snow-ice melting using finite element software.Compared with the test result,the correctness of the test result is verified.It also puts forward suggestions for further research.
