摘要: In this study, four novel boron-containing additives were synthesised chemically in the laboratory. The modification was performed by adding additives, respectively, into asphalt at a certain amount weight same temperature and mixing conditions. mechanism microstructure of blends characterised Fourier transform infrared spectrometer scanning electron microscopy. variation modified samples comparison to base investigated performing penetration, softening point, dynamic shear rheometer, amplitude–frequency–temperature sweeps rotational viscosity tests. It observed that increased rutting resistance, elastic properties asphalt. additive with triazole borate ester octanol-sulphuric acid catalysts gave most enhancements, relative
