摘要:
为了研究混合料密实度对温度的敏感性,在室内进行了不同温度、击实次数下的马歇尔试件密实度试验,确定了压实温度对沥青混合料压实性能的影响;建立了基于热传导学原理的混合料摊铺温度散失有限元模型,对低温工况下混合料温度散失规律进行研究,并通过实测数据对计算模型进行验证分析.研究结果表明:温度低于100℃时,即使增加击实功也很难使混合料达到98％以上的压实度;低温环境下摊铺层厚度越小,沿深度方向混合料温度分布越离散,压实难度越大;摊铺厚度以2 cm梯度从10cm降低到4 cm时,有效碾压时间分别降低9.7％、25％和24％.
Abstract:
In order to study the influence of temperature on compaction degree,theory density change rule ofMarshall specimens was studied under different temperatures and compaction times.A mixture temperature lostmodel was established based on heat conduction theory to study asphalt mixture heat losing under low tempera-ture,this model was also verified by observation data. The results show that: asphalt mixture was difficult tobe compact to 98% degree under 100 ℃. As thin as the pavement was, the temperature distributed more scat-tered and the compaction become more hard. Thickness of pavement decreases from 10 cm to 4 cm by 2 cmgrads,the effective rolling time decreases by 9.7% ,25% ,24% .
