The design of the pavement structure can make use of moduli to predict its performance during a preset lifetime. It is essential to study static and dynamic moduli characteristics. The static modulus was derived from the compression rebound modulus of the hot-mixed asphalt. The dynamic modulus was checked against a simple performance tester. The modulus of a cold recycled emulsified asphalt mixture was tested in a series of experiments on cement contents, emulsified asphalt contents, loading frequency, and temperature. The results show that high cement and asphalt contents resulted in a lower compression rebound modulus. The dynamic modulus maximum is reached at a 2% cement content. The dynamic modulus also increases with the loading frequency. This increase is observed during the early period. When the frequency increased to 10 Hz, an increase in the dynamic modulus becomes linear, and its rate gradually decreases.

冷再生乳化沥青混合料的静态和动态模量

路面结构的设计可以利用模量来预测其在预设寿命期间的性能。研究静态和动态模量特性至关重要。静态模量来自热混合沥青的压缩回弹模量。用简单的性能测试仪检查动态模量。在一系列关于水泥含量,乳化沥青含量,加载频率和温度的实验中测试了冷再生乳化沥青混合物的模量。结果表明,高水泥和沥青含量导致较低的压缩回弹模量。在水泥含量为2%时达到最大动态模量。动态模量也随着加载频率而增加。在早期观察到这种增加。当频率增加到10 Hz时,
