棉秸秆纤维沥青混合料性能研究

Study on performance of cotton straw fiber asphalt mixture

以棉秸秆纤维作为沥青混合料的增强材料,研究棉秸秆纤维制备过程中的关键因素对其增强性能的影响。通过控制棉秸秆纤维制备时的浸泡程度、喂料前的含水量和粉碎室内的打散时间三个关键工艺参数,根据棉秸秆纤维的吸油性、耐热性、吸湿性、棉秸秆纤维掺入沥青胶浆的延伸度等评价,确定最佳的制备工艺流程。

The effect of the key factors in the process of preparing cotton stalk fiber on the reinforcing properties of cotton stalk fiber was studied.According to the oil absorption,heat resistance,hygroscopicity and the incorporation of cotton straw fiber into the cotton straw fiber by controlling the degree of soaking in the preparation of cotton fiber,the moisture content before feeding and the breaking time in the crushing chamber,Asphalt mortar elongation and other evaluation,to determine the best preparation process.
