Study on utilising waste toner in asphalt cement

Khedaywi, Taisir S.

Every year, large quantities of waste toner come from either the manufacturing processes or from copying machines and laser printers. This material causes environmental pollution as well as costly disposal problems. In this research, an attempt to partially overcome these problems was made through using this waste in asphalt concrete mixtures in flexible pavement of road surfaces. The main objective of this research was to study the effect of waste toner on the properties of the asphalt cement. An asphalt cement of a 60/70 penetration grade was used in this study. The waste toner was added to the asphalt cement at five contents (0%, 5%, 10%, 15% and 20% by volume of the asphalt cement). Tests including penetration, ductility, specific gravity, softening point, flash point, fire point and rotational viscosity were carried out on each of the prepared binders. The test results were analysed to determine the effect of the waste toner content on the measured properties of the asphalt cement. Tests results showed that with the increase in the waste toner content in the binder, penetration and ductility decreased while specific gravity, softening point, flash point, fire point and rotational viscosity increased.
