- 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.
