摘要

本研究采用高岭土和海泡石纳米粘土对SBS改性沥青进行加固。所使用的纳米粘土与文献中的材料不同，具有容易找到、经济且可从当地获得的特性。在生产前确定了混合参数。在基础沥青中分别以3%和5%的比例添加聚合物添加剂SBS，在聚合物改性沥青中分别以2%和4%的比例添加纳米粘土添加剂。荧光显微镜下观察其形态结构。比较了样品的物理和流变性能。通过贮存稳定性试验考察了相分离情况。此外，采用零剪切粘度(ZSV)和多应力蠕变恢复(MSCR)试验方法对样品的车辙性能进行了测试。

Preparation and Performance Testing of SBS Modified Bitumens Reinforced with Halloysite and Sepiolite Nanoclays

In this study, halloysite and sepiolite nanoclays were used to reinforce SBS modified bitumens. The nanoclays used are different from the materials in the literature and have properties such as easy to find, economical and available from local sources. The mixing parameters were determined before production process. The polymer additive SBS was added into base bitumen at 3% and 5%, the nanoclay additives were added into polymer modified bitumen at 2% and 4% ratios. The morphological structures were investigated under fluorescence microscope. Physical and rheological properties of the samples were compared. The phase separation cases were investigated by storage stability test. Furthermore, rutting performance of samples was measured with zero shear viscosity (ZSV) and multi stress creep recovery (MSCR) test methods.

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
