| 摘 要： | 结合天定高速沥青路面工程,量测了施工中热拌沥青混合料和温拌沥青混合料内部及表面的温度,探讨了两种沥青混合料施工中不同时刻的温度变化差异,并根据灰色理论建立了热拌和温拌沥青混合料施工中温度变化的GM(1,1)模型。结果表明:热拌沥青混合料与温拌沥青混合料表面温度变化差异不大;初压过后的温拌沥青混合料内部温度明显大于热拌沥青混合料各个时刻的内部温度;建立的施工中热拌与温拌混合料内部及表面温度变化预测模型精度较高,可以预测温拌沥青混合料的温度变化,对温拌沥青混合料有效施工时间的确定具有重要的参考作用。

| Abstract: | Relying on the asphalt pavement construction engineering from Tianshui to Dingxi,internal and surface temperature of hot asphalt mixture and warm-mix asphalt was measured and the difference between them at different time was discussed.The GM(1,1) model on the temperature variation during hot mix asphalt and warm-mix asphalt paving was established based on the Grey theory.The results show that the surface temperature variation is not obvious for hot asphalt mixture and warm-mix asphalt.After the initial comp... |
