Abstract

In this study, the effects of mixing temperature on the performance of hot mix asphalt (HMA) were investigated. 5% Styrene-butadiene-styrene (SBS) and 18% America Gilsonite were used as binder modifiers. HMA samples were prepared at the mixing temperatures 10°C, 15°C, and 20°C lower temperatures than the mixing temperature. Marshall Stability and flow, resistance to moisture-induced damage and indirect tensile fatigue tests were conducted on the hot mix asphalt samples. As a result of the experimental study, it was determined that the use of additives increased the performance of the HMAs. In addition, it was determined that, in general, the stability, Marshall quotient, indirect tensile strength and fatigue life of the mixtures decreased and the flow values increased with decreased mixing temperature.

混合温度对热拌沥青力学性能的影响

研究了混合温度对热拌沥青性能的影响。使用5%的苯乙烯-丁二烯-苯乙烯（SBS）和18%的America Gilsonite作为粘合剂改性剂。HMA样品在比混合温度低10°C、15°C和20°C的混合温度下制备。对热拌沥青样品进行了马歇尔稳定性和流动性、抗湿损伤性以及间接拉伸疲劳试验。实验研究的结果表明，添加剂的使用提高了HMA的性能。此外，还确定，通常情况下，混合物的稳定性、马歇尔商、间接抗拉强度和疲劳寿命随着混合温度的降低而降低，流动值随着混合温度降低而增加。

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.
