基于沥青混合料的粘弹性理论,研究了不同降温速度、不同降温起始温度、不同温缩系数对剩余应力和应力松弛量的影响,结果表明:随着降温速度的增加,温度应力累积速度也变快,降温速度越快,温度应力会越大;降温起始温度对应力松弛量的影响微小;温缩系数越大,剩余应力和应力松弛量都明显增大;随着温度的不断变低,剩余应力和应力松弛量均有一定的增长,剩余应力累积的速度较松弛量快。在设计时,应对路表温度应力或温度应变进行考虑。 Based on the viscoelasticity theory of asphalt mixture, the effects of different cooling rates, different initial temperature and different temperature shrinkage coefficients on residual stress and stress relaxation are studied. The results show that with the increase of cooling rate, The faster the temperature is, the faster the temperature is and the greater the temperature stress is. The lower the initial temperature of cooling is, the smaller the influence of the stress relaxation is. The larger the temperature-shrinkage coefficient is, the larger the residual stress and stress relaxation are. , The residual stress and the amount of stress relaxation have a certain increase, the rate of residual stress accumulation faster than the slack. At design time, temperature stress or temperature strain should be considered.
