Evaluation of mechanical properties for stone mastic asphalt containing textile waste

Abstract

Bitumen draining in stone mastic asphalt mixtures has become a potential problem. Due to the storage and laying temperatures as well as difficulties in providing the necessary compaction, the temperatures of the asphalt mix cannot be lowered to prevent or reduce drainage. In stone mastic asphalts, generally cellulose or mineralbased fibers are preferred to reduce draining down of bitumen. Conventional fibers commonly used in stone mastic asphalt increase pavement costs because they are expensive.The aim of this research is investigation of textile waste used to prevent bitumen drainage problem in stone mastic asphalt pavements instead of traditional fibers. Following the determination of the bitumen content, Marshall Stability tests, Schellenberg bitumen drainage test and Indirect Tensile Strength tests were conducted to evaluate the mechanical properties of the stone mastic asphalt mixtures in comparison to mixes containing textile waste. The results indicated that it is possible to produce stone mastic asphalt mixes with textile waste that exhibits similar mechanical properties mixes including cellulose fiber. Moreover, it was found that samples prepared with textile waste exhibits advantage in terms of cost compared to samples prepared with cellulose fiber.

Estabilización De Mezclas Asfálticas Stone Mastic Asphalt (Sma) Mediante Inhibidores De Drenaje Como Fibras De Basalto

“…Para Oner (2023), además de prevenir obstrucciones, algunos inhibidores de drenaje también actúan como agentes repelentes, reduciendo la adhesión de sustancias oleosas en las superficies de drenaje. Esta propiedad no solo contri-buye a mantener la permeabilidad de los sistemas, sino que también ayuda a prevenir la contaminación del agua al disminuir la cantidad de contaminantes transportados por el escurrimiento superficial.…”

Quality properties of recycled yarns obtained by recycling fabrics produced from virgin yarns

“…Recycling is defined as the conversion of the components in the waste into other products or energy by physical, chemical or biochemical methods by taking advantage of the properties of the wastes [2]. With another definition; recycling is the integration of recyclable waste materials, which are not used in any way, to the production processes as raw materials by various recycling methods [3,4]. These materials are textiles, paper, glass, plastic, motor oil, batteries, concrete, aluminum, organic wastes, electronic materials and such wastes [5].…”
