摘要:
由废弃碎玻璃(WGC)所制备的玻璃沥青混合料容易发生水损破坏。采用预制1 mol/L的NaOH溶液对WGC进行浸润表面化学处理,并利用预先配制好的氨丙基三乙氧基硅烷(AMEO)偶联剂水解溶液对其进行化学修饰,通过扫描电子显微镜法、X射线荧光光谱术、傅里叶变换红外光谱术和粒度分析,评价化学修饰对WGC微观结构、化学成分、分子结构与粒径分布的影响,同时通过冻融劈裂与浸水马歇尔试验检测,研究化学修饰后的玻璃骨料对沥青混合料水稳定性的影响。结果表明:NaOH溶液对WGC亲水性与表面粗糙度的提升具有显著效果,同时能促进AMEO对WGC的有机化修饰效果。相较于WGC,NaOH/WGC会使沥青混合料出现浸水松散与间接拉伸强度比低的现象,导致无法检测浸水残留稳定度且间接拉伸强度比仅为30.3%,而AMEO对NaOH/WGC进行化学修饰后,浸水残留稳定度恢复至96.7%,间接拉伸强度比达76.7%,表明WGC的表面修饰作用具有显著提高玻璃沥青混合料抗水损害的能力。
Abstract:
The glassphalt mixtures prepared by waste glass cullet (WGC) is prone to damage. In this study, we used a prefabricated 1 mol/L NaOH solution to chemically treat the WGC by immersion, and chemically modified it by using a pre-formulated aminopropyl triethoxysilane(AMEO) coupling agent hydrolysis solution. Using scanning electron microscopy,X-ray fluorescence spectroscopy,Fourier transform infrared spectroscopy, and particle size analyzer,the effects of chemical modification on the microstructure,chemical composition,molecular structure and particle size distribution of WGC were evaluated. Moreover,the freeze-thaw splitting and Marshall water-immersion tests were carried out to determine whether the chemical modification promotes the enhancement of glass asphalt’s resistance to water. The results show that NaOH solution enhances the hydrophilicity and surface roughness of WGC,as well as promotes the organic modification of WGC with AMEO. Compared with WGC,NaOH/WGC makes the asphalt mixture loose in association after immersion with a low indirect tensile strength ratio, causing the immersed residual stability can not be tested and indirect tensile strength ratio only reaches 30.3%,while the immersed residual stability is recovered to 96.7% and the indirect tensile strength ratio is 76.7% after further chemical modification of NaOH/WGC with AMEO,demonstrating that the modification of WGC has significant capacity of improving glassphalt’s resistance to the moisture-induced damage.
