摘要:
基于压剪破坏理论,建立了密级配沥青混合料高温蠕变失稳点预测模型,并研究了模型参数的影响因素.利用三轴压缩试验,获得沥青混合料不同围压下高温抗压强度和抗剪强度参数.在相同温度及对应围压下,实施不同载荷水平的三轴动态蠕变试验,得到混合料高温失稳点对应的流变次数FN,分析了不同围压下FN变化规律,建立了一个新的预测FN模型.此外,通过试验对掺加不同添加剂混合料的FN预测值进行了验证,进一步分析了级配及温度对模型参数的影响.结果表明,沥青混合料失稳点FN预测结果与试验结果有较好一致性,改变级配或试验温度均会对预测模型参数产生较大影响,而添加剂的影响则可忽略,当温度为60 ℃时AC20级配混合料参数a,b值比AC13级配参数分别减小约52.1%,18.3%,且同一级配材料随温度升高,参数a波动较大,b则增长明显.
Abstract:
The prediction models of the creep instability points of dense-graded asphalt mixtures were established at high temperatures, and the influence factors of model parameters were studied, based on the pressure-shear failure theory. First, the compressive strength values under different confining pressures and shear strength parameters were obtained through triaxial compression tests at high temperatures. Secondly, multiple repeated pressure values were applied to dynamic triaxial creep tests at the same temperature and corresponding confining pressure, and the rheological numbers(FN)corresponding to the creep instability points of the asphalt mixtures were obtained. Thirdly, the prediction models of the asphalt mixtures were established by analyzing the change law of FN under different confining pressures and cyclic loading pressures. Finally, the FN values of the different additive mixtures were predicted using the models. The reliability of the prediction results was verified by the test. Furthermore, the influence factors of model parameters were studied by changing the graduation and test temperatures. Results show that the predicted FN values of the asphalt mixtures are in agreement with the experimental results, and the model parameters are affected by the graduation and test temperatures. But the influence of additive can be ignored. The parameters a and b of AC20 gradation mixture are reduced by nearly 52.1% and 18.3%, respectively. The parameter a waves significantly, and the parameter b increases obviously with the increase of the temperature under the same gradation mixture.
