摘　　要：针对新型道路热蓄能融雪化冰技术的道路太阳能集热过程中路面吸热性的温变作用开展实验研究,探索道路表面作用的太阳辐射吸热特性,并重点研究了沥青、特制涂黑、光滑和粗糙处理表面的道路的实验路板吸收太阳能辐射的温变特性。实验分析可知,表面温度波动较为剧烈4,种路面表现出明显的太阳能辐射吸收能力差别,特制涂黑表面路板具有最强的吸热能力,比其他3种材料分别高2.96%、18.42%和23.93%。研究表明。The effect of surface absorbability on temperature variation in the slab with solar radiation, which is one of the essential compositions of a new road hydronie ice-snow melting technology using the seasonal solar energy storage, was explored experimentally in this paper. The solar radiation absorbability of slab surface was researched and the characteristics of temperature variation in four structures, such as asphalt, special coating black, smooth and rough were mainly studied. The experimental results show that the temperature fluctuation of upper surface was more intense, and there was a big difference of absorbing solar radiation energy among the four kinds of surfaces. The surface with a special coating black got the largest heat absorption capacity, which was higher than others （ asphalt, smooth and rough） by 2.96%, 18.42% and 23.93%, and the surface structure produced an effect on the heat penetration capability in the road slab.
