Abstract:

In order to investigate the rheological properties of the modified asphalt compounded with reactive elastomer terpolymer （RET）， polyphosphoric acid （PPA） and SiO2 aerogel （SG）. Firstly， the three modifier doping amounts were determined by using the three index tests； the high and low temperature properties and permanent deformation resistance of the modified asphalt were analyzed by DSR， BBR and MSCR tests. Fourier transform infrared spectroscopy， fluorescence microscopy and scanning electron microscopy were used to study the modification mechanism and microscopic properties of asphalt. The results showed that the incorporation of RET， PPA and SG improved the high and low temperature performance of the asphalt. Compared with the as-built asphalt， the complex shear modulus of the composite modified asphalt increased by 170%； creep stiffness decreased by 35 MPa at -12 °C and creep rate increased by 21.3%. The aerogel and the two polymers were mainly physically blended， and the modification process generated new absorption peaks. The aerogel improved the compatibility of the asphalt interface， and the modifier particles were uniformly dispersed， which improved the asphalt road performance.

Key words: road engineering, modified asphalt, rheological properties, modification mechanism, reactive elastomer terpolymer, polyphosphoric acid, SiO2 aerogel
