“…The test results indicates that the IRS increase with increasing LDPE ratio, and the rate of increase in the index of retained strength is improving significantly with 9% of recycled LDPE material. This behavior is also remarked by other researchers [16]. They attributed this behavior to the bonding ability of the polyethylene polymer with aggregates particles, acting as glue to bind the aggregate particles together and reduce waste ingress.…”

“…This enhancement may be attributed to the bonding ability of the recycled plastic polymer. Since recycled polyethylene works as a "glue" [16] to bond aggregate particles and strengthens the aggregate-binder matrix. Although, there is a reduction in pavement performance with a 9% of LDPE rate as compared to the previous rate.…”

“…However, Angelone et al [15] recommended using LDPE as flakes in the paving mixture. Singh et al [16] stated that the inclusion of shredder polyethylene to the asphalt mixture enhances the volumetric properties, Marshall stability, and flow for the mixture. Also, it improves the recovered asphalt binder in terms of complex modulus and phase angle.…”

With the industrial revolution, many inventions have been introduced with many solid waste materials in return. This study investigates the potential recycling of waste plastic sheets, made from low-density polyethylene, as asphalt modifier in the paving mixture. The shredded plastic sheet was used in the asphalt mixture via the wet process. The dosage rate was set up to 9 % by weight of asphalt binder (0,3,6, and 9)%. The experimental program was designed to assess the mechanical properties (Marshall stability and flow, and volumetric properties), durability, and short-term aging of asphalt mixtures, in addition to economical assessment. The test results revealed the applicability of using this solid waste material in paving construction as a surface layer, since its usage enhances the pavement performance by increasing stability, index of retained strength, and volumetric characteristics before and after aging as well as saving in cost. The best enhancement can be achieved with 6% of recycled low-density polyethylene.

“…They found that asphalt mixtures containing PE showed an improvement with respect to the Marshall strength, flow and volumetric properties. The frequency sweep tests indicated that PE improved the complex modulus while decreasing the phase angle of the recovered bitumen (Singh et al, 2017). However, the addition of PE failed to significantly improve the low-temperature flexibility of bitumen (Isacsson and Lu, 1995).…”

Rutting and fatigue of asphalt pavements, as two important distresses, are significantly influenced by the properties of binders. This study aims to improve the rutting resistance and fatigue behavior of asphalt mixtures by using two recycled waste polymer components of recycled crumb rubber (CR) and polyethylene (PE). Their contribution and mechanisms on enhancing the pavement performance were evaluated, in particular rutting and fatigue behavior of asphalt mixtures. The assessed pavement properties of the modified asphalt mixtures were evaluated by wheel tracking, uniaxial penetration and four-point bending (4PB) tests. The experimental results showed that the integrated modification technique by functionally incorporating PE and CR can improve the rutting resistance of asphalt mixtures, and the PE dosage was a key variable. The integrated modification method can enhance the shear strength of asphalt mixtures at a high inservice temperature, indicating the potential to reduce the flow rutting of asphalt pavements. Meanwhile, both the CR and PE can increase the cohesive behavior of asphalt mixtures, while the friction angle value was mainly determined by PE. The addition of PE reduced the fatigue life of asphalt mixtures, while CR was able to improve the fatigue properties of the PE modified asphalt mixture. The findings of this study are beneficial to develop sustainable and durable asphalt pavements, to tailor the reuse of different types of polymer wastes in asphalt pavements as well as to minimize the waste disposal at landfills.
