| 摘 要： | 本文采用弯曲试验和低温弯曲蠕变试验,针对3种典型级配的沥青稳定碎石基层混合料,进行了低温抗裂性能检验。分析表明:应变能密度临界值指标评价沥青混合料的低温抗裂性能更加科学;沥青稳定碎石矿质混合料级配对低温抗裂性影响较大,级配偏上限有较好的低温抗裂性能。

| Abstract: | To three representative gradation mixture of asphalt treated base course,this paper verified crack resistance in low temperature by means of bending test and creep test in low temperature.Analysis indicated critical value' index of strain energy density was much more scientific to appraise crack resistance in low temperature of bituminous mixture;mineral mixture' gradation of asphalt treated base course had relatively great influence for crack resistance in low temperature,and it was better when gradation l... |
