摘要
设计一种油性聚氨酯类超薄磨耗层,采用万能试验机分析其拉伸性能,并通过小型环岛加速加载仪器研究其抗滑性能,基于国际摩擦指数IFI综合评价超薄磨耗层的抗滑性能和耐久性。结果表明:纳米碳酸钙有增强树脂的物理性能以及减少其收缩率。确定了胶结料的最佳用量和最佳铺装工艺,并在此条件下得出了防滑粒料的最佳粒径。引入国际摩擦指数IFI综合评价3种不同防滑粒料的超薄磨耗层的抗滑性能以及适用的环境。
An oil-based polyurethane ultra-thin wearing course was designed.Its tensile properties were analyzed by universal testing machine,and its anti-sliding performance was studied by small-scale island acceleration loading instrument.The anti-sliding performance and durability of ultra-thin wearing course were evaluated based on international friction index IFI.The results showed that nano calcium carbonate can enhance the physical properties of the resin and reduce its shrinkage.The optimum amount of cementitious material and the optimum paving technology were determined,and the optimum particle size of antiskid granular material was obtained under this condition.The international friction index(IFI)was introduced to evaluate the anti-sliding performance and applicable environment of ultra-thin wearing course of three different antiskid granular materials.
