摘要
通过对5种不同玄武岩纤维掺量的混合料进行室内试验,以研究玄武岩纤维掺量对改性沥青混合料路用性能的影响。由试验可知,随着纤维掺量的增加,混合料的高温稳定性不断提高,在纤维掺量为0.3%后增幅不断减小;玄武岩纤维的掺入可以提高混合料的低温稳定性,掺量为0.2%时效果最佳;混合料的抗水损能力随玄武岩纤维掺量增加而提高,在掺量为0.5%时达到最大。
The indoor experiment of basalt fiber mixture with five different dosage was carried out to study the influence of basalt fiber content on the properties of modified asphalt road.According to the test,the high temperature stability of the mixture can continuously increase with the increase of the fiber quantity,and the increase in the quantity of fiber is decreased when the contentis more than0.3%;the mixing of basalt fiber can improve the cold stability of the mixture,which is the best when it is 0.2%;thewater damage resistance of the mixture increases and reaches the maximum when the dosage is 0.5%.
