摘要
利用红外摄像仪记录摊铺路面的温度分布情况,然后对碾压完成的路面钻取芯样并测试芯样密度,在排除级配离析对芯样密度的影响后,分析温度与密度之间相关性。研究结果表明,沥青混合料温度与密度之间存在良好的线性相关性,从而根据现有的密度差离析评价标准定量的得到了温度离析评价标准。
The infrared thermal camera1 was used to record temperature distribution of asphalt pavement,then core samples were drilled through the completed pavement and the density of core samples was tested, the correlation between temperature and density was analyzed excluding the effect of gradation segregation on density. The research results showed that a well linear correlation was found between temperature and density of asphalt mixture, and based on the existing segregation evaluation standard of density difference, the evaluation standard of temperature segregation was got.
