【摘要】：該文通過對EWMA-1溫拌劑、水性溫拌劑(天津市政工程研究院研發(fā))、EC120、Aspha-min共4種國內(nèi)外溫拌劑進行試驗,研究其對膠粉改性瀝青的降黏效果及常規(guī)性能的影響。對70#鎮(zhèn)�；|(zhì)瀝青和膠粉改性瀝青(19%膠粉)進行針入度、軟化點、延度、黏度和老化試驗,對4種溫拌劑的黏度-溫度曲線進行研究。試驗結(jié)果表明:4種溫拌劑在一定程度上均能提高膠粉改性瀝青的軟化點,降低黏度與針入度,雖然5℃延度有所下降,但仍滿足規(guī)范要求;水性溫拌劑與Aspha-min溫拌劑可以提高膠粉改性瀝青的抗老化能力;分析黏度-溫度曲線可知:EC120溫拌劑與Aspha-min溫拌劑對膠粉改性瀝青的降黏程度大于其他兩種溫拌劑,且降黏幅度在50%以上。
[Abstract]:In this paper, four domestic and international warm mix agents, EWMA-1 warm mix agent and waterborne warm mix agent (R & D of EC120 Aspha-min), were studied to study the effects on viscosity reduction and conventional properties of asphalt modified by rubber powder. The penetration, softening point, ductility, viscosity and aging test of 70# Zhenhai base asphalt and rubber powder modified asphalt (19% rubber powder) were studied. The viscosis-temperature curves of four kinds of warm mix agents were studied. The test results show that the softened point of asphalt modified by rubber powder can be improved and the viscosity and penetration of asphalt can be reduced by the four kinds of warm mixing agents. Although the ductility of 5 鈩，
