碱侵蚀对玄武岩纤维沥青性能影响改善研究
STUDY ON THE EFFECT OF ALKALI CORROSION ON THE PERFORMANCE OF BASALT FIBER ASPHALT
摘要
Abstract
In order to enhance the reinforcement and strengthening effect of basalt fiber (BF) in asphalt,surface treatment of BF by 1.0 moL/L and 2.5 mol/L NaOH solution was performed.The surface morphology of BF was observed by environmental scanning electron microscopy (ESEM) and infrared spectroscopy (IR) test.The results show that the surface of original BF was smooth,and BF showed a clear core structure by NaOH solution treated from the ESEM.With the increase of NaOH solution concentration and treatment time,the results show that the higher the-OH content of BF is from the IR test.The basalt fiber asphalt of high,low temperature performance and drawing fracture morphology were studied,by softening point,5 ℃ ductility,rutting factor and ESEM test.The results show that the higher the degree of erosion of BF by NaOH solution,the better the performance of basalt fiber asphalt.And,the best treatment time and concentration of NaOH solution for BF erosion were:45 min,2.5 mol/L.关键词
