摘要:

研究了纳米碳酸钙改性沥青的路用性能,应用差示扫描量热分析法(DSC)对纳米碳酸钙改性沥青进行了试验分析,从吸热量和比热容两个方面研究纳米碳酸改性沥青高温稳定性和温度敏感性,探讨温度稳定性改善机理.研究表明,纳米碳酸钙能够提高基质沥青高温稳定性;比热容物理意义明确,测量方便,可以评价沥青的高温稳定性质.

Abstract:

The road performance of nano-calcium carbonate-modified bitumen was studied, and the differential scanning calorimetric analysis (DSC) was used to test and analyze the nano-calcium carbonate-modified bitumen, and the high temperature stability and temperature sensitivity of nano-carbonate-modified bitumen were studied from the aspects of heat absorption and specific heat capacity, and the temperature stability improvement mechanism was discussed. Studies have shown that nano-calcium carbonate can improve the high temperature stability of matrix asphalt. The specific heat capacity has clear physical significance and convenient measurement, and the high temperature stability quality of bitumen can be evaluated.
