“…Many researchers have also reported that the correlation between the rutting factor and pavement rutting depth is not strong enough, and the MSCR test is considered a substitute [ 42 ]. Typically, MSCR tests are carried out to obtain deformation parameters to evaluate the high-temperature rutting resistance of asphalt binders [ 43 , 44 , 45 , 46 ]. Fewer studies have focused on the deformation behavior of asphalt binders from an energy perspective.…”

The polyphosphoric acid (PPA) modified asphalt binder is a potential choice as one of the pavement materials for its excellent high-temperature performance and low cost. To further analyze the influences of temperature and load on the service life of pavement from the perspective of deformation behavior, six kinds of asphalt binders with different PPA dosages were prepared for Multiple Stress Creep and Recovery (MSCR) tests at five temperature levels. The deformation behavior is investigated by basic deformation parameters, rheological simulation, and energy parameter changes. The results show that the percent recovery (R) drops sharply while non-recoverable creep compliance (Jnr) goes up slightly with the increase in temperature. Three-element model, composed by E1, η1, and η2, can be used to describe the creep behavior. PPA-modified asphalt binder exhibits nonlinear creep behavior, and the logarithmic model can simulate recovery behavior better than the power–law model. Stored energy and dissipated energy can characterize the change of energy in the creep process under different conditions and show a significant correlation to deformation parameters. It is concluded that the elastic component of asphalt binders is increased by PPA, which is beneficial to the improvement of the deformation resistance and recovery capacity of asphalt binders. The recommended dosage of PPA is 1.5%. This investigation is conducive to a better understanding of the deformation behavior of PPA-modified asphalt binders and provides a reference for its engineering applications.

“…The vast majority of polymers correspond to long chains of molecules composed of many units (monomers) linked together by covalent bonds. These compounds have good properties for use in areas such as medicine and tissue engineering (1,2), engineering and energy (3,4), agriculture (5,6), mining (7), among others, however, being in the presence of high temperatures their structure becomes highly viscous due to the entanglement of the molecules (8,9). Due to the large number of existing polymers we can find different classifications:…”

Since 1950 plastics became the materials of greatest world production. Thus, in recent years the increase in the use of different types of plastics has been a matter of global concern due to the depletion of fossil fuels and the accumulation of waste in the different environmental matrices, affecting the ecosystem. By 2015, 4.9 million metric tons of plastic waste were recorded in landfills, because more than 40% of the plastics produced are designed for single use. The mass amount of plastic is estimated to exceed 450 million tonnes per year and will double by 2045.Due to the great problem of plastics and their threats to the ecosystem, the researchers worked on a large number of technologies to mitigate the effect of plastics on the different environmental matrices. Therefore, the main goal of this manuscript is summarizes on the plastics more used as well as the most common techniques to reduce their presence at the environment.
