摘 要: | 冬季冰雪天气严重影响着城市交通和道路交通,为了尽快的使道路上的积雪融化,研究一种既方便又快捷的材料---碳纤维-玻璃纤维格栅,将这种材料作为导电发热体铺设在路表面下,在冰雪天气对导电发热体进行通电、产生热量,通过热传递的方式使路表面温度升高.文中对铺设了碳纤维-玻璃纤维格栅的沥青混凝土路面进行升温和融雪模拟试验,研究了2种不同铺设方案下,在温度为-6.5℃、发热通电功率控制在300 W/m2时路面结构模型的升温情况,表明将格栅铺设在路面表层5 cm以下较为合理.通过现场的融雪试验表明,这种路面能实现融化积雪的功能.

Abstract: | Snow accumulation and ice in winter produce serious obstacles for traffic all over the world . In order to remove snow and ice as quickly as possible ,one type of convenient and efficient conductive grating material-carbon fiber-glass fiber grating is laid into the pavement as electric heating element , which can be powered on and produces quantity of heat ,and then the temperature of the road rises and snow is melted .Two different pavement models are tested in a testing chamber with the air tempera-ture of-6 .5℃ and the electricity power of about 300W/m2 .It is found that the reasonable arrange-ment of carbon fiber-glass fiber grating inside the pavement is 5cm below the surface of pavement . Field tests have also been performed to melt snow .Results show this method can be worked . |
