Abstract

Increasing traffic volumes, heavier loads on Egyptian road network cause several pavement distresses. Several trials were done to eliminate pavement distresses by using some additives. One of the cheapest methods for mix enhancement is to use the solid waste material such as plastic and fly ash. This study aims to investigating the effect of using fly ash and waste plastic on the properties of asphalt concrete mixtures. To achieve the study objectives, Marshall Test was conducted on standard mix without additives as a reference and on two groups of asphalt concrete mixtures. In the first group different percentages of fly ash was used instead of fine aggregate. While in the second group, different percentages of waste plastic Resin instead of fine aggregate portion in hot mix asphalt with a combination of the best percentage of fly ash instead of fine aggregate in hot mix asphalt was used. Finally, some special tests were performed to measure the different mix characteristics. These tests included loss of stability test and wheel tracking test. Analyzing the study results it can be concluded that the use of waste plastic resin and fly ash greatly enhance the rutting depth and properties of asphalt mixtures compared with conventional asphalt mixtures. Finally the study recommended using two proposed mixes .the first mix consists of 2% fly ash instead of fine aggregate portion in hot mix asphalt (HMA). While the second mix consists of 9% waste plastic resin with a combination of a 2% fly ash instead of fine aggregate portion in hot mix asphalt.
