Physical and microstructural properties of new boron resin compound synthesized asphalt

摘要: Over the last 20 years, many polymer-based additives have been used in asphalt modification. The extensive utilization of these additives and their inability to biodegrade create environmental concern for humans. Therefore, discovering affordable and naturally occurring asphalt polymers has become prominent. In this study, a new asphalt modifier was produced under laboratory conditions by synthesizing boron oxide with rosin (colophony resin), which is naturally produced from pine trees. Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC)/thermogravimetric (TG), and X-ray powder diffraction (XRD) analyses were used to determine the microstructural characteristics of the produced modifier. The SEM analysis showed that the new modifier was distributed homogeneously the asphalt matrix, the FTIR and XRD analyses showed that a …
