In the current study, the synthesis of a novel additive containing boron and its inclusion in asphalt binder was completely achieved under chem. laboratory conditions. Following this objective, the structural analyses of the additive containing boron, namely Cyclic Borate Ester (CBE), and the modified asphalt binders were examined The asphalt binders were blended with CBE additive in 1%, 2%, 4%, and 6% (weight/weight) ratios at each stage of the experiment The elemental analyses of CBE were performed using the Fourier transform IR (FTIR) spectroscopy test, the thermogravimetry (TG), and the proton NMR (1H NMR) spectroscopy test. The mechanisms of the modification in the modified asphalt binders were researched using FTIR while their microstructures and thermal degradation behaviors were analyzed via SEM (SEM) and TG tests. In the analyses the rheol. behaviors of the blends were investigated by the temperature-frequency-amplitude sweeps in dynamic shear rheometer (DSR) test. According to the exptl. results, it was seen that there was no phase separation between CBE and the asphalt matrix. There was an electrostatic interaction between asphalt and CBE ′s hydrocarbon chain. Accordingly, it was observed that the rutting resistance and elastic characteristics of the base asphalt binder investigated in the study were increased by including CBE. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Related Products of 57-55-6).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Related Products of 57-55-6
