摘要
对TLA改性沥青及基质沥青进行了油蚀试验,并对油蚀后的沥青试样进行了针入度、软化点、当量软化点和粘度等试验,结果表明,油蚀后沥青高温性能显著下降,但随着TLA掺量的增加,试样的高温性能和抗变形能力有所提高。
Oil corrosion experiments were operated on matrix asphalt and TLA modified asphalt.Subsequently,asphalt samples after oil corrosion were tested on the softening point,equivalent softening point,viscosity and so on.The results shows that the asphalt performance decreased significantly after oil corrosion,but with the increased mixing amount of TLA,the high temperature performance and anti-deformation capacity of asphalt samples were improved.
