Abstract

To deeply show the internal reasons for the effects of epoxy resin and curing agent on the high-temperature performance of asphalt, nine kinds of asphalt with different content of epoxy resin and curing agent were prepared. On the premise of ensuring that the softening point, penetration and ductility of epoxy asphalt no attenuation, the dynamic shear rheology test and Saybolt viscosity test were used to examine the rutting factor (G*/sin δ), complex shear modulus (G*), phase angle (δ), and viscosity of asphalt with different epoxy resin and curing agent contents. With the help of fluorescence microscopy, microscopic morphology was analyzed, and the micro-image was further analyzed quantitatively by using 3Dsurface and particle statistics. The results show that adding epoxy resin and curing agent into asphalt can significantly improve the rutting factor and complex shear modulus of asphalt and reduce the phase angle and the viscosity growth rate of asphalt changed from fast to slow. Fluorescence and 3Dsurface imaging results indicate when the epoxy resin and the curing agent are uniformly distributed and forms microflocculent structures, the epoxy resin can fully swell in asphalt, and the fluorescence intensity is uniform. The statistical analysis of particles shows that the improvement in high-temperature performance of asphalt by epoxy resin and curing agent results from the distribution of particle area above 26.7346 μm². The high-temperature performance of epoxy asphalt is optimal when the content of epoxy resin and curing agent is 6 %.

Dalam usaha secara mendalam untuk menunjukkan sebab dalaman kesan resin epoksi dan agen pengawetan pada prestasi suhu tinggi Asfalt, sembilan jenis daripada asfalt dengan kandungan resin epoksi dan agen pengawetan telah disediakan. Dalam usaha untuk memastikan takat pelembutan, penembusan dan kemuluran epoksi asfalt tiada pengecilan, ujian reologi ricih dinamik dan ujian kelikatan Saybolt digunakan untuk memeriksa faktor rut (G*/sinδ), modulus ricih kompleks (G*), sudut fasa (δ) dan kelikatan asfalt resin epoksi berbeza serta kandungan agen pengawetan. Dengan bantuan mikroskopi pendarfluor, morfologi mikroskopi telah dianalisis dan imej mikro dianalisis lebih lanjut secara kuantitif menggunakan statistik 3Dsurface dan statistik zarah. Keputusan menunjukkan bahawa penambahan resin epoksi dan agen pengawetan ke dalam asfalt boleh menambah baik secara signifikan faktor rut dan modulus ricih kompleks asfalt serta mengurangkan sudut fasa dan kadar pertumbuhan kelikatan asfalt berubah daripada laju kepada perlahan. Pendarfluor dan keputusan pengimejan 3Dsurface menunjukkan apabila resin epoksi dan agen pengawetan diagihkan secara seragam dan membentuk struktur mikroberflokulasi, resin epoksi boleh membengkak sepenuhnya dalam asfalt dan keamatan kependarfluoran adalah seragam. Analisis statistik zarah menunjukkan pembaikan dalam prestasi suhu tinggi asfalt oleh resin epoksi dan agen pengawetan hasil daripada taburan kawasan zarah di atas 26.7346 μm². Prestasi suhu tinggi asfalt epoksi adalah optimum apabila kandungan resin epoksi dan agen pengawetan adalah 6%.
