Abstract

In the past decade, the road network in Jordan has been exposed to a large volume of traffic, leading to distress in the pavements and consequently the need for continuous maintenance and rehabilitation of the network. The main objective of this study was to evaluate the effect of replacing limestone dust in the asphalt mixtures by different filler materials (waste toner, waste glass, waste rubber and electric arc furnace dust) on Marshall properties and on reducing the permanent deformation. Superpave specimens were prepared to determine the permanent deformation under dry and wet conditions with a wheel tracking device. The device applies moving loads on the samples and the consequential rutting can then be determined. The results of Marshall tests showed that the use of waste toner, waste rubber and electric arc furnace dust can enhance the Marshall properties, whereas waste glass filler did not. The results also showed that the permanent deformation of specimens modified by waste toner, waste rubber and electric arc furnace dust was less than for the reference mixtures by (82.2%, 43.6%, 28.7%) and (58%, 32.5% and 14.2%) at dry and wet conditions, respectively. In contrast, specimens with waste glass filler had increased permanent deformation compared with the reference mixtures by 64% and 23% at dry and wet conditions, respectively.
