通过研究脱硫胶粉与普通胶粉两种材料制备的橡胶沥青,进行橡胶沥青胶浆体系指标的系统研究。室内研究得出:当橡胶粉掺量为20%,橡胶沥青胶浆体系确定出的最佳粉胶比为1.0;采取感温指数VTS作为橡胶沥青胶浆体系温度敏感性能的评价指标;针对橡胶沥青胶浆体系,动态剪切流变仪由室内试验确定出适合的试样厚度即1.5mm,从复数黏度、复合弹性模量、车辙因子等手段评价橡胶沥青胶浆体系的流动特性、抗永久变形和抗车辙能力。 By studying the rubber asphalt prepared from two kinds of materials, desulfurized rubber powder and common rubber powder, the system research of rubber asphalt mortar system index was carried out. Indoor research shows that: when the content of rubber powder is 20%, the best ratio of rubber powder to rubber asphalt mortar system is 1.0; VTS is used as the evaluation index of temperature sensitivity of rubber asphalt mortar system; Asphalt mortar system and dynamic shear rheometer, the suitable sample thickness is 1.5mm determined by laboratory test, and the flow characteristics of rubber asphalt mortar system are evaluated from complex viscosity, composite elastic modulus and rutting factor, etc., anti-permanent Deformation and rutting ability.
