Study on thermal properties of steel Slag asphalt concrete for snow-melting pavement
Journal of Cleaner Production, 2020Co-Authors: Wenxiu Jiao, Aimin Sha, Zhuangzhuang Liu, Wei Jiang, Wen Qin, Hu YuanjiaoAbstract:Abstract The utilization of steel Slag in asphalt concrete can improve the thermal conductivity of steel Slag asphalt concrete. The thermal conductivity of asphalt concrete largely affects the surface temperature distribution of asphalt pavement, which in turn affects the mechanical characteristics of asphalt pavement and the temperature of the environment near the surface pavement. In this study, the thermal properties of asphalt concrete with different steel Slag Volume contents were investigated in a laboratory. The thermal conductivity was tested using a parallel hot-wire and transient plane source method, and the uniformity and surface temperature were studied through infrared thermal imaging. Next, a 3D infrared image was analyzed based on regional statistics, image binarization, and the coefficient of variation evaluation. The practical snow melting efficiency of thermally conductive asphalt concrete was evaluated using an electrical-thermal system. Experimental results indicate that the thermal conductivity, heating distribution uniformity, and surface temperature of asphalt concrete are first increased, before decreasing with an increase in the steel Slag replacement. Regardless, the thermal properties of steel Slag asphalt concrete were shown to be better than those of conventional asphalt concrete. The most effective steel Slag Volume in asphalt concrete was shown to be 60 vol. %. The snow melting efficiency of thermal conductivity asphalt concrete can be improved using an electrical-thermal system. The results of this study will help mitigate a shortage of natural resources and improve the temperature distribution of pavements.

Utilization of steel Slags to produce thermal conductive asphalt concretes for snow melting pavements
Journal of Cleaner Production, 2020Co-Authors: Jiao Wenxiu, Aimin Sha, Zhuangzhuang Liu, Wei JiangAbstract:Abstract This study focuses on the thermal conductivity of steel Slag asphalt mixtures. The initial aim of this study was to verify the feasibility of adding steel Slag to asphalt mixtures as a thermal aggregate to increase the thermal conductivity for electrical-thermal snow melting. The thermal conductivity of different rock aggregates and steel Slags were firstly tested, before the surface temperatures of different-sized particles of the target steel Slag was measured. In addition, the thermal conductivity and engineering performances of asphalt mixtures with different steel Slags contents were measured. Experiment results indicate that diabase and hot-stuffy steel Slag possesses higher thermal conductivity, and that particles of sizes 9.5–13.2, 1.18–2.36 and 0.3–0.6 mm are the most effective sizes. The thermal conductivities of the asphalt mixtures firstly increased, before decreasing with increasing steel Slag replacement, and the thermal conductivity reached a peak for a steel Slag Volume replacement of 6%. All of the steel Slag asphalt mixtures meet the required engineering performance, and the steel Slag asphalt mixtures played a positive role in the snow melting process on an electrical-thermal pavement system, compared with ordinary asphalt mixtures.

Utilization of steel Slag as aggregate in asphalt mixtures for microwave deicing
Journal of Cleaner Production, 2017Co-Authors: Jie Gao, Aimin Sha, Zhenjun Wang, Zheng Tong, Zhuangzhuang LiuAbstract:Abstract Under the dilemma of non-renewable natural resources shortage and environmental pollution issues, as a novel aggregate used in asphalt pavement, the application of steel Slag is propitious to the improvement of the environment and the enhancement of economics. Meanwhile, steel Slag has great potential for microwave heating as an excellent microwave absorbing material, which can contribute to remove the ice layer on the pavement. The primary objective of this work was to explore the feasibility of the usage of steel Slag as the aggregate of asphalt mixtures for microwave deicing, and ascertain the most effective Volume and particle sizes for partial replacement of conventional aggregate. The deicing mechanism of microwave heating pavement was firstly introduced. Then, the microwave heating capacity of steel Slag with different particle sizes was tested and the surface elements distribution of steel Slag was measured. In addition, the XRD test was conducted to analyze the material information of steel Slag for its microwave heating capacity. Finally, the surface temperature, thermal conductivity and heating uniformity of asphalt mixture containing different steel Slag content were tested. Results show that the particle sizes of 9.5 mm, 2.36 mm and 0.6 mm are considered as the most effective sizes. The thermal conductivity and microwave heating uniformity of asphalt mixtures basically decrease with the increase of steel Slag content; while the surface temperature presents a contrary trend. Consequently, the suggested steel Slag Volume content is 40% and 60%; and the particle sizes of steel Slag are selected as 9.5 mm, 2.36 mm and 0.6 mm. The comprehensive evaluation results on the supply sources, environmental hazard and cost of steel Slag show great feasibility of its utilization in asphalt mixtures for microwave deicing, which is helpful to alleviate the supply shortage of natural aggregates and improve the safety of road traffic in winter.
