Plastics have prominent utilization worldwide. Polyethylene Terephthalate (PET) is one of the major types of plastics that can be found in Municipal Solid Waste (MSW). MSW contains a high proportion of thermoplastic polymers which have been increasing in value. PET is a semi-crystalline thermoplastic polymer and is considered a polyester material. A large amount of waste PET is being produced in the form of different products, for instance, bottles, fibers, molding, and sheets are the products mostly manufactured in Europe by application of PET. The utilization of PET is well-known in the food industry because of the superlative characteristics offered by PET as a packaging material, mainly as bottles.
On the other hand, during the last decades, the number of vehicles on roads, especially heavy vehicles such as vans and trucks, has increased. To overcome these problems and make a better mixture providing longer service life, modifying asphalt mixture by utilizing additives such as fibers and polymers comes into popularity among road engineers and designers. Hence, this presentation aims to assess the effects of adding waste PET as an additive on permanent deformation characteristics and fatigue life of asphalt mixture.
Dr. Soltani and his colleagues attempted to characterize the rutting behaviour of waste PET-modified asphalt mixture under static and dynamic loadings. They found the relationships between the deformation and other mixture properties. Based on their results in the case of the dynamic test, the PET waste-modified asphalt mixtures were associated with lower cumulative permanent strain values.
In addition, mixtures containing waste plastic bottles had more stability values and fatigue life compared to the conventional mixture. This innovative idea certainly proved that adding waste plastics could even enhance the quality of the asphalt mixture and turn the asphalt mixture into a more durable and sustainable material that could be resulted in the longer service life of the highway with lower maintenances costs.
