Abstract

Modification of the asphalt mixtures by using the waste materials is one approach that is taken to improve the flexible pavement performances. This study presents the feasibility and practicality of using recycled waste glass as fine aggregate in hot mix asphalt (HMA). It focused on deformation characteristics of waste glass reinforced Hot Mix Asphalt. Laboratory investigation had been conducted on the samples of Asphaltic Concrete Wearing Coarse (ACW 14). The testing undertaken in this study are Marshall Test, Resilient Modulus Test, Dynamic Creep Test and Wheel Tracking Test. The crushed waste glass used to replace fine aggregate were added in a variety of proportions such as 5% , 10%, 15% and 20% where all the percentages are calculated by weight of mixes. The HMA without glass are prepared as a control sample. Marshall Test had been carried out in this study to establish the optimum bitumen content (OBC) and to know the effects of waste glass on mix design parameters. Resilient Modulus Test is used to determine the loading effect in the mix, whereas Dynamic Creep Test and Wheel Tracking Test are carried out to identify the deformation performances of Asphaltic mixture. The modified mixtures with added waste glass were compared to conventional mixture, and finally the differences of deformation characteristic are stated. It was found that ideal glass percentage is 5%. Additional of glass with 5% gave better results in resisting the deformation against dynamic load and may be used in heavy traffic conditions.
