Study on pore characteristics of cold-mixed multi-component reactive asphalt mixture based on mercury intrusion test
Long term service of cement concrete pavement panels in civil airports often leads in surface degradation and other diseases caused by freeze-thaw cycles. However, conventional overlay repair materials typically exhibit insufficient low-temperature toughness. To address this issue, this study propos...

| description | Long term service of cement concrete pavement panels in civil airports often leads in surface degradation and other diseases caused by freeze-thaw cycles. However, conventional overlay repair materials typically exhibit insufficient low-temperature toughness. To address this issue, this study proposes a cold-mixed multi-component reactive asphalt material. Mercury intrusion porosimetry (MIP) was employed to characterize the pore structure of two cold-mixed multi-component reactive asphalt mixtures with varying polyester fiber contents. The results reveal a significant increase in pores ranging from 5000 to 30,000 nm after freeze-thaw cycling. The incorporation of polyester fibers enhances the water stability of the mixture. Furthermore, macroscopic freeze-thaw splitting tests confirm the superior freeze-thaw resistance of polyester fiber-modified cold-mixed multi-component reactive asphalt mixtures. |
