一种通过应力响应分析评价沥青温度敏感性的方法
摘要：
本发明涉及一种通过应力响应分析评价沥青温度敏感性的方法，即通过测定宽温度域内沥青动态应力响应曲线，确定沥青黏弹态温度区间，从而确定应力响应在黏弹态温度区间的变化速率，以此来实现沥青温度敏感性的评价。通过试验表明，应力响应变化率能够很好地区分不同品质沥青的温度敏感性，对于道路建设中沥青材料的选择提供了有效的试验方法。
摘要（英）：

The invention relates to a method for analyzing and evaluating temperature sensibility of asphalt through stress responses. According to the method, by determining a dynamic stress response curve of the asphalt within a wide temperature domain, a viscoelasticity state temperature range of the asphalt is determined, thus the change rate of the stress response at the viscoelasticity state temperature range is determined, and then the temperature sensibility of the asphalt is evaluated. As is shown through tests, the temperature sensibility of the asphalt with different qualities can be well distinguished according to the change rate of the stress responses, and an effective test method is provided for selecting asphalt materials in road construction.
