为研究导电沥青混凝土发热的影响因素及发热效果,优化沥青混合料配合比,制作导电试块,分析电压和纤维质量分数对试块发热升温的影响,并进行真雪的融化试验.结果表明:电压越高发热升温越高,安全电压12,24和36V均能满足要求;碳纤维质量分数越大升温越高,达到0.23%后温度升高趋于稳定,0.28%时发热升温性能最好;通电24V具有良好的融雪效果,随着通电时间的延长导电沥青混凝土的融雪效率成倍增加,通电20,40和60min时,融雪效率分别提高了50.00%,66.67%和91.67%.
In order to study the influencing factors and heat-generating effects of conductive asphalt concrete heating, the proportion of asphalt mixture was optimized to make conductive test blocks, the influence of voltage and fiber mass fraction on the heat-up of test blocks was analyzed, and the real snow melting test was carried out. The higher the voltage is, the higher the heating temperature is and the higher the safety voltage is. The higher the carbon fiber mass fraction is, the higher the temperature is. When the temperature rises to 0.23%, the temperature rises to stabilize. The heating temperature rises best at 0.28% 24V has a good snowmelt effect. As the energization time prolongs, the snowmelt efficiency of conductive asphalt concrete multiplies, and the snowmelt efficiency increases by 50.00%, 66.67% and 91.67% at 20, 40 and 60min respectively.
