Multiple-response optimization of open graded friction course reinforced with fibers through CRITIC-WASPAS based on Taguchi methodology


Abstract: Multiple benefits in terms of safety, water quality runoff and noise mitigation have been reported from using Open graded Friction Courses (OGFCs) as wearing course. However, their use is quite limited due to raveling phenomenon. The main objective of this study is to evaluate the functional and mechanical performance of OGFCs reinforced with nylon and polypropylene fibers. To this purpose, a Design of Experiments (DOE) was conducted considering three control factors named as fiber type, binder content and fiber content. Different responses such as total air voids, interconnected air voids, particle loss in dry conditions and particle loss in wet conditions were recorded. In addition, a multi-objective optimization was carried out through the CRITIC-WASPAS methodology. The results showed the effect of adding nylon fibers on the increase of the abrasion resistance in dry and wet conditions. According to the multi-criteria decision-making analysis, the design involving nylon fibers, 4.80% binder content and 0.06% fiber content turned out to be the experimental design better ranked.
