The Use of Waste Materials to Modify Binder in Asphalt Concrete

The behaviour of the asphalt concrete mix containing waste materials in binder was studied. Waste materials used in this research are fly ash and plastic milk cartoon. The waste materials were prepared with different content by weight of binder and modified binder properties have been evaluated in terms of penetration test at various temperatures (25oC, 30oC, 35oC and 40oC) and softening point test. The laboratory test revealed that the penetration values of modified bitumen were found lower than unmodified bitumen but the softening values showed higher than unmodified bitumen. Marshall tests were carried at optimum bitumen content to evaluate the effect fly ash and plastic milk cartoon on the properties of asphalt concrete in terms of rutting resistance (stability), unit weight, air void in mix, void in mineral aggregate and stripping resistance. Test results showed that the performance of bitumen mixes prepared using waste materials as modifier were better than origin bitumen mixes.
