摘要

为制备分散性良好的碳纤维导电沥青混合料,通过单因素实验考察了碳纤维含量、搅拌时间、分散剂质量浓度对沥青混合料中碳纤维分布系数的影响,并通过高温车辙试验、低温弯曲试验、水稳定性试验以及微观形貌和结构分析研究了碳纤维导电沥青混合料的综合路用性能。结果表明:碳纤维质量分数为0.3%、搅拌时间为6.0min、分散剂质量浓度为4.0g/L时,沥青混合料中碳纤维分散效果最佳;分散后的碳纤维导电沥青混合料的动稳定度与抗弯拉强度分别为3792次/mm和14.9MPa,比不含碳纤维的沥青混合料分别提升7.3%和8.9%,制备的沥青混合料具有更好的高温稳定性和低温抗裂性,水稳定性有所下降,但满足规范要求。

Abstract

In order to prepare the carbon fiber conductive asphalt mixture with good dispersibility,the effects of carbon fiber content,stirring time and dispersant mass concentration on the carbon fiber distribution coefficient in the asphalt mixture were investigated by single factor experiments,and the comprehensive road properties of the carbon fiber conductive asphalt mixture were studied by high temperature rutting test,low temperature bending test,water stability test as well as microscopic morphology and structure analysis.The results showed that when the mass fraction of carbon fiber was 0.3%,the stirring time was 6.0min,and the mass concentration of dispersant was 4.0g/L,the carbon fiber dispersion effect in asphalt mixture was the best.The dynamic stability and tensile strength of the dispersed carbon fiber conductive asphalt mixture were 3792 times/mm and 14.9MPa,respectively,which were 7.3% and 8.9% higher than that of the asphalt mixture without carbon fiber,respectively.The prepared asphalt mixture exhibited improved high-temperature stability and low-temperature crack resistance.Although the water stability slightly decreased,it still met regulatory requirements.
