摘要
文中针对不同养护参数和酸酐组分对环氧沥青断裂自愈合性能的影响展开试验.结果表明,在酸酐组分增加的情况下,环氧沥青的自愈合能力不断下降,其拉伸应变能力不断变差,而其拉伸强度却逐渐变大;养护时间越长,环氧沥青的断裂自愈合拉伸强度和拉伸应变越大;环氧沥青的自愈合能力会随着养护温度的升高而提高,与拉伸强度相比,拉伸应变具有更强的温度敏感性.
Abstract
In order to make epoxy asphalt more widely used,the effects of different curing parameters and anhydride components on the fracture self-healing properties of epoxy asphalt were tested.The results show that with the increase of anhydride,the self-healing ability of epoxy as-phalt decreases,its tensile strain capacity decreases,and its tensile strength increases gradually.The longer the curing time,the stronger the tensile strength and tensile strain of epoxy asphalt.The self-healing ability of epoxy asphalt increases with the increase of curing temperature.Compared with the tensile strength,the tensile strain has stronger temperature sensitivity.
