“…For instance, it can be washed, dried, and extruded [21,29,30], which is particularly important if it comes from consumption. If the waste is almost clean it can also be directly trimmed or grinded [5]. The size of the particles added to the binder can vary between 0.3 and 0.5 mm [5,11,31].…”

“…In this respect, the mixing temperature varies between 150 and 180 • C, the digestion time between 3 min to 4 h, and the speed of the mixer employed ranges between 120 and 7200 rpm ( represent the changes in penetration and softening point achieved through the addition of the different polymers ( Figure 4 and 5), were made so as to summarize the data of the several references included in each section for the different reclaimed polymers reviewed in this paper. In relation to the characteristics of the RPMB manufactured with polyethylene (PE), in general terms, as the amount of PE added to the binder increases, the softening point increases whilst penetration decreases [5,18,29]. This indicates a more rigid behavior of the mixture and, consequently, a higher resistance to permanent deformations, particularly at high temperatures.…”

Polymers commonly used in binder modification can be divided into three main categories: thermoplastic elastomers, plastomers, and reactive polymers [5]. In spite of the fact that these modifiers can improve the thermal susceptibility of asphalt binders, each category has a specific effect on their properties: Thermoplastic elastomers mainly enhance the elastic properties of the binder (increasing fatigue resistance), while plastomers or reactive polymers primarily act by increasing the stiffness and the resistance against deformation in response to loading [6].…”

The use of polymer-modified binders in asphalt mixtures has become more widespread due to their reduced thermal susceptibility and improved rutting and fatigue resistance. Nevertheless, their high cost limits their application, thus making the use of reclaimed polymers (RP) an interesting alternative for both reducing price and extending the service life of pavements. This paper; therefore, presents a comparative review of the recycled polymers most commonly studied as bitumen modifiers: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ethyl vinyl acetate (EVA), and ground tire rubber (GTR), in order to facilitate their selection and extend the use of the bitumen. The differences in terms of melting point, mixing conditions, and maximum quantity of added polymer are analyzed. Moreover, their effect on the mechanical behavior of the asphalt binders and their stability with and without the use of additives is presented. According to the literature revision, the performance of the new binder is more influenced by the kind of polymer that was incorporated and the mixing conditions than by the base bitumen that was chosen, although rheological evaluation is needed to fully understand the modification mechanisms of the modified binder. In general terms, plastomers have a stronger effect in terms of increasing the stiffness of the bitumen in comparison with crumb rubber (elastomers), thus providing an improved rutting resistance. The joint use of polyethylene (plastomer) and crumb rubber (elastomer) can be an interesting option for its recycling potential and mechanical performance, although further study is needed to achieve stable bitumen across the entire range of temperatures; additives, such as maleic anhydride (MA), are commonly employed to improve the stability of the binder and enhance its characteristics, but their use could limit the economic benefits of using recycled materials.

 Abstract: Porous asphalt is designed to have a relatively higher porosity than other pavement types, this porous property is obtained because the proportion of fine aggregate is less than other types of mixtures. In an effort to increase the strength of porous asphalt pavement structures, it is required to use other added materials both as additives, stabilizers and substitution materials. In this study, the added material used was low density polyethylene (LDPE) plastic waste as a substitute for asphalt and coconut-shell ash (CA) as filler substitution material. Stone ash, cement and fly ash are commonly used as fillers in asphalt mixture, CA is expected to be one of the alternatives. This study aims to determine the characteristics of using LDPE into asphalt pen. 60/70 and the use of 50% CA filler on the characteristics of porous asphalt mixture and to find out indications of deficiencies and strengths in the asphalt mixture. On the initial bitumen content without using substitutes, the optimum bitumen content (OAC) was 5.76% with the variation used of LDPE 3%, 5% and 7% and 50% CA as filler. At OAC value 5.76% with 3% LDPE substitution meet all required parameter. With the value of Marshall Stability, VIM, Flow, AFD, and CL are 560.50kg, 18.61%, 4.3mm, 0.22% and 19.69% respectively.
