中文摘要:
      为进行热态沥青混合料铺筑热扩散影响因素的分析,将铺筑热扩散影响因素划分为环境条件、铺层条件和下承层条件三类。首先基于可信性得到验证的仿真模型进行了三类因素的仿真试验,其次应用正交试验法和方差分析对不同类中的各因素进行了敏感性分析。结果表明:环境条件中气温和风速有显著影响,太阳辐射和有效辐射的敏感性较弱;铺层条件中厚度、混合料类型和摊铺温度影响敏感,混合料的集料类型敏感性弱;下承层条件中的材料类型有显著影响,厚度对铺筑热扩散不敏感;基于本文所提出的上述规律量化,可预测不同工程条件下的回避条件,或在不利环境下采取针对性技术方案,进而保证铺筑压实质量。
英文摘要:
      In order to analyze the factors of thermal diffusion of asphalt mixture paving, these factors were divided into environmental conditions, spreading layer conditions and underlying layer conditions. Firstly, simulation experiments of three kinds of factors were carried out based on the simulation model which was verified by credibility. Secondly, the sensitivity of factors in different classes were analyzed by orthogonal tests and variance analysis. Results show that air temperature and wind speed have a significant impact on the environmental conditions, and the sensitivity of solar radiation and effective radiation is weak. Thickness, mixture type and spreading temperature are sensitive in spreading layer conditions, and the sensitivity of aggregate type in spreading mixture is weak. Material type in underlying layer conditions has significant influence, but the thickness of underlying layer is not sensitive to the thermal diffusion of paving. Based on quantitative measurement above the research, avoidance conditions under different engineering conditions could be predicted, or specific technical schemes could be adopted in unfavorable environment to ensure the compaction quality of pavement.
