| 摘 要： | 低温是造成沥青路面开裂的重要因素.通过不同材料破坏试验的应力-应变曲线求取应变能,并以弯曲应变能作为评价沥青低温性能的标准,同时以约束温度应力试验的结果验证评价结果的合理性.研究表明:采用弯曲应变能作为评价指标可以很好地表征材料的低温性能,并且与约束试件温度应力试验的结果基本吻合.

| Abstract: | Low temperature is an important factor causing the asphalt pavement crack,it is necessary to research on the asphalt mixture low-temperature performance.It calculated strain energy by the stress-strain curves of curvature rupture test,then used curvature strain energy as an evaluation of the low-temperature performance of asphalt standards,and at the same time evaluated the reasonableness of the evaluation results by the thermal stress restrained specimen test results.It is found that curvature strain energ... |
