IMPROVEMENT FOR ASPHALT MIXTURE PERFORMANCE USING PLASTIC BOTTLE WASTE

Lately, plastic waste has become a problem in our society, due to the negative impact that it has on our environment. To mitigate this, the reuse of plastic bottle wastes and other local materials should be encouraged. In this paper, the authors present an innovative application for polyethylene terephthalate (PET) that is obtained from plastic bottle wastes, as an additive to Asphalt Concrete-Wearing Course (AC-WC), a hot mix asphalt (HMA) type. The AC-WC sample that contained the PET was measured using the wet method to determine the Marshall parameters of the samples. The type of bitumen used as the specimen is asphalt, which has a penetration value of 60/70. The optimum asphalt content (OAC) obtained from the preliminary study was found to be 5.7% of the total asphalt weight. The results show that AC-WC mixture strength improves when plastic bottle waste is used, which can be correlated with an increase in stability. This finding shows that plastic bottle waste and other local materials have an alternate use as a road pavement material.
