改性沥青的储存稳定性是指在一定的时期内处于高温条件下储存、运输及使用时,改性沥青维持原有性状的能力。无机改性剂能改善沥青的路用性能,但改性剂与沥青的相容性较差易于发生离析,从而造成改性沥青性能的稳定性差。本文研究了温轮胶对无机改性剂改性沥青储存稳定性的影响。研究表明:温轮胶的掺入可以使|ΔT|呈现减小的趋势,并使|ΔG*|和|Δδ|均明显减小,说明温轮胶的掺入可以提高无机改性剂改性沥青的储存稳定性。
Modified asphalt storage stability refers to the ability of the modified asphalt to maintain its original character when stored, transported and used under high temperature for a certain period of time. Inorganic modifier can improve the road performance of asphalt, but the compatibility of modifier and asphalt is easy to segregation, resulting in poor stability of modified asphalt. In this paper, we studied the effect of warm rubber on the storage stability of inorganic modified asphalt. The results show that: the incorporation of warm rubber can make | ΔT | reduce the trend, and | ΔG * | and | Δδ | were significantly reduced, indicating that the incorporation of warm rubber can improve the modification of inorganic modifier Asphalt storage stability.
