摘要
为解决日益严重的车辙问题和城市热岛效应,使用废陶瓷代替部分集料形成陶瓷热阻磨耗层。首先介绍了废陶瓷的处理过程,通过马歇尔试验确定了在不同的陶瓷掺量下的最佳沥青用量,采用常功率平面热源法测试了不同陶瓷掺量的沥青混合料的导热系数,并通过室内模拟太阳辐射试验系统测试热阻材料的阻热效果。验证了陶瓷热阻磨耗层材料的水稳定性、高温和低温性能。试验结果表明,使用陶瓷代替部分骨料可以有效地降低材料的导热系数,选用合理的陶瓷掺配比例,可以得到满足路用性能要求的热阻磨耗层。
To solve the rutting and Urban Heat Island effect,ceramic thermal resistance wearing course is designed by using abandoned ceramic instead partial aggregate.Treatment process of waste ceramic is introduced.The optimum asphalt content for different ceramic dosage is determined by Marshall experiment.The thermal conductivity is tested by plane heat source method.The heat isolation effect is tested by indoor solar radiation simulation system.The road performance,water sensibility,high-temperature and low-temperature are tested.The results show that using ceramic instead of partial aggregate can decrease the thermal conductivity of mixture.By choosing the optimum dosage of ceramic,the thermal resistance wearing course can fit for requirement of road.
