Abstract

Porous pavement applications, which is environmentally friendly, especially for residential areas, allow rainwater to remain clean and to feed groundwater through infiltration. Porous asphalt pavements, in which are among the pavement types used in porous pavements systems, also reduce environmental noise pollution. On the other hand, there is a need to improve the performance of these asphalt pavement mixtures, which have a short service life due to their porous structure. It has been considered to improve the performance of the pavement mixtures by using basalt fiber without compromising the hydraulic permeability level. The waste slag material released during the ferrochrome production process was used as aggregate in the porous asphalt mixture design. Thus, it is aimed to benefit from the economic and environmental aspects with the recycling of ferrochrome slag in an area suitable for its properties. In the study, the design performances of porous asphalt mixtures were determined with tests such as volume analysis, permeability, Cantabro particle loss, indirect tensile strength, and moisture susceptibility. Basalt fiber was added at 0.2%, 0.4%, 0.6% and 0.8% of the mixture weight. It has been determined that the mixtures of basalt fibers at 0.2% significantly improve the mechanical performance.

玄武岩纤维改性多孔沥青混合料的性能评价

多孔路面应用，这是环保的，特别是对住宅区，使雨水保持清洁，并通过渗透补给地下水。多孔沥青路面是多孔路面系统中使用的路面类型之一，它也减少了环境噪声污染。另一方面，这些沥青路面混合料由于其多孔结构，使用寿命较短，需要提高其性能。利用玄武岩纤维可以在不影响透水性能的前提下改善路面混合料的性能。将铬铁生产过程中产生的废渣料作为集料进行多孔沥青混合料设计。因此，在适合其性质的地区回收铬铁渣，旨在从经济和环境方面受益。在研究中，通过体积分析、渗透性、Cantabro颗粒损失、间接抗拉强度和水敏感性等测试来确定多孔沥青混合料的设计性能。玄武岩纤维的添加量分别为混合物重量的0.2%、0.4%、0.6%和0.8%。经测定，0.2%的玄武岩纤维掺量显著改善了材料的力学性能。

期刊介绍： The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
