摘要
为研究保水路面、热阻路面和储热路面的调热特性,对三种调热路面的调热机理进行了分析;通过成型三种调热路面试件和普通沥青路面试件,并在试件底部设置温度传感器,采用温度采集仪对四种路面的温度变化数据进行了采集,研究结果表明,储热路面的温度变化相对于普通沥青路面存在一定的滞后性;三种调热路面均能降低路面温度,但降低幅度保水路面最大,热阻路面居中,储热路面最小。
For the study of the thermal characteristics of water-retention pavement,thermal resistance pavement,heat storage pavement,the heat transfer mechanism of three kinds of heat transfer asphalt pavement was analyzed;the three kinds of heat transfer asphalt pavement specimens and normal asphalt pavement specimens were formed,and the temperature sensors were set at the bottom of specimens,and the temperature data of four kinds of pavement were collected. The results show that the temperature change of heat storage pavement lags behind the normal asphalt pavement;all the three kinds of heat transfer pavements can effectively reduce the pavement temperature,but the water-retention’s cooling effect is the best,thermal resistance is center,thermal storage’s cooling effect is poorer.
