Abstract

Economic growth and the increase in the population trigger consumption and increase the amount of waste produced. One of the resulting wastes is glass and using of these large amount of glass waste materials by environmental methods is seen as an important issue. On the other hand, there are difficulties due to the decrease of natural resources in the supply of aggregates used in asphalt pavements. In this study, the use of waste glass instead of natural aggregates in asphalt pavements was investigated in terms of water damage. In addition to base bitumen, hydrated lime modified and SBS modified bitumen were used in experimental studies. The waste glass was added in two different sizes (as filler materials and 2 mm sized fine aggregate) and three addition ratios (20%, 30% and 40%) instead of basalt aggregates. The asphalt mix samples produced in optimum bitumen contents were evaluated for water damage by AASHTO T 283 method. Asphalt mixture with 20% glass filler showed the highest water damage resistance. Among the options where the glass aggregate size was chosen as 2 mm, the highest water damage resistance was realized at addition rate of 30%. Both hydrated lime and SBS polymer were effective in improving water damage resistance. However, the highest tensile strength ratio was obtained with hydrated lime. The optimum bitumen contents of the mixtures with glass aggregates produced with both base and modified bitumen were decreased compared to that produced entirely with basalt aggregate. According to the test results, it is understood that the filler materials produced from waste glasses can be used instead of natural aggregate filler.

玻璃颗粒尺寸对沥青混合料水损伤性能影响的评价

经济增长和人口增长引发了消费，并增加了产生的废物量。由此产生的废物之一是玻璃，通过环保方法利用这些大量的玻璃废料被视为一个重要问题。另一方面，由于自然资源的减少，沥青路面用骨料的供应也存在困难。本研究以废玻璃代替天然集料用于沥青路面的水损伤研究。除基础沥青外，还采用水合石灰改性沥青和SBS改性沥青进行了实验研究。用两种不同粒径(填料和2mm细骨料)和三种添加比例(20%、30%和40%)的废玻璃代替玄武岩骨料。采用AASHTO t283方法对最佳沥青掺量下的沥青混合料样品进行水损害评价。掺加20%玻璃的沥青混合料抗水破坏性能最高。当玻璃骨料粒径为2 mm时，掺量为30%时，抗水损伤性能最高。水合石灰和SBS聚合物均能有效提高材料的抗水损伤能力。然而，水合石灰的拉伸强度比最高。与完全用玄武岩骨料生产的混合料相比，用基础沥青和改性沥青生产的玻璃骨料混合料的最佳沥青含量降低。根据试验结果了解，用废玻璃生产的填料可以代替天然骨料填料。

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.
