Investigation of textile waste usage in stone mastic asphalt (SMA) mixtures

Abstract

Stone mastic asphalt pavements are preferred worldwide as they are more resistant to heavy traffic loads. The stone mastic asphalt pavement design involves the use of 70-80% of coarse aggregate, 8-12% of filler, 5-7% of binder, and approximately 0.3-0.5% of fibre. The gap-graded structure and high binder content of stone mastic asphalt cause bitumen to drain down from aggregates. Marshall test and Schellenberg bitumen drainage test are performed in this research on samples prepared with different quantities of textile waste and cellulose fibre. The results of the research show that textile waste can be used instead of traditional fibres.
