不同掺和物对沥青混凝土路面融雪性能的影响

Effects of Different Additives on the Snowmelt Performance of Asphalt Concrete Pavement

针对当下冬季传统道路除雪除冰方式的不足,以烟威地区降雪量数据为例,讨论了新型沥青混凝土导电路面与传统路面除冰除雪方式的差异,并对石墨钢纤维复合沥青混凝土路面和碳纤维电热格栅沥青混凝土路面进行了除冰实验对比,进而在碳纤维电热格栅沥青混凝土路面的基础上进行了改良。证明无论是出于安全考虑还是出于经济考虑采用埋设碳纤维格栅的沥青混凝土路面进行路面自融雪都是一种行之有效的方式。

Because the existing methods of deicing and snow removal are inefficient for the ice-snow road in winter,conductive asphalt concrete pavement as a new deicing and snow removal method was proposed.The deicing and snow removal principle of conductive asphalt concrete pavement was discussed with comparison to the existing deicing and snow removal method based on the data of yantai and weihai snowfall.The deicing experiments were performed on the graphite/steel fiber asphalt concrete pavement and carbon fiber electric grid asphalt concrete pavement and an improvement was proposed on the carbon fiber electric grid asphalt concrete pavement.The experimental results show that embedding carbon fiber grating in the asphalt concrete pavement embedded is an effective method for cleaning up ice-snow road on the basis of the safety and economy.
