“…Because SBS has the superior properties of plastic and rubber simultaneously and SBS modified asphalt has good high and low-temperature performance. It is the main modifier for asphalt used in many hightemperature and high-cold areas at home and abroad [16]. However, the cost of SBS is higher, and WR the cost price only accounts for one-third of SBS.…”

In this study, it is shown how recycled rubber and waste plastics can modify the softening point and penetration of asphalt traditionally used for highways. It is shown that the modified asphalt can meet the performance index requirements when the components are present with a certain proportion or relative ratio (1:3.5). The dispersion process of the masterbatch in base asphalt can effectively be implemented, with good results and a smaller mixing time. The proposed approach may be regarded as a good strategy to achieve energy savings and protection of the environment.

“…Its additional components include hydroxyl aldehydes, hydroxyl ketones, sugars, carboxylic acids and phenols (Chen et al, 2019). Fini et al (2017), were successful in converting pig compost into oil at a pressure of 40 MPa and temperature of 380 C. According to Nie et al (2020), bio-oil exhibit comparable constituents just like asphalt binder obtained from crude oil which could be categorized as asphaltenes, polars, aromatics and saturates. However, due to the high content of oxygen presence in bio-oil, its primary elements also vary notably from well-known asphalt (Lozano et al, 2020).…”

The rate at which the construction industry explores and consumes non-renewable natural aggregates and other industrial products such as bitumen, lime, and cement during construction and rehabilitation of road pavements has over time proven to be environmentally degrading and non-sustainable. This, alongside the issues of high solid waste generation and inadequate disposal, has led to series of studies by various researchers to find methods to integrate these solid wastes as alternative materials in road construction and maintenance. This paper provides a simple yet detailed review of recent relevant studies conducted to understand the alarming rate of generation and the effects of reusing these waste materials in both flexible and rigid pavements. The review further outlines the advantages and disadvantages of the selected waste materials and compare the results with that of conventional materials in accordance with relevant standards while highlighting the performance, and life cycle environmental and economic sustainability implications. The study shows that the adoption of these materials offers efficiency in waste disposal while reducing the demand for natural aggregates and consequently, significantly reducing life cycle impacts and costs. The challenges limiting the effective practical implementation of these waste recycling techniques in the construction industry were discussed and possible solutions were suggested to encourage and ensure its utilization in road construction.

“…However, the main goal in these studies was not to increase the workability of bitumen. Generally, waste oils were used as rejuvenators [23][24][25] or compatibilizers [26] of SBSMB. In addition, there are studies aiming to examine the effects of waste oils on fatigue life [27], aging resistance [28], and chemical and rheological properties [29][30][31][32] of SBSMB.…”

Nowadays, the use of waste materials in various industries is becoming widespread in order to promote waste recycling. Thus, scientists are researching the use of waste materials in bitumen modification. In this study, it was aimed to investigate the effect of waste cooking oil (WCO) on the physical and rheological properties of unaged Styrene-Butadiene-Styrene modified bitumen (SBSMB) by adding WCO at different ratios (1, 3, 5, 7, and 9%) to SBS modified bitumen. Accordingly, rotational viscosity (RV) tests and rheological tests with dynamic shear rheometer (DSR) based on the determination of complex shear modulus (|G*|) and phase angle (δ) were conducted along with the traditional bitumen tests. As a result of the experimental study, it was observed that adding WCO increased the workability and fatigue resistance of SBSMB, however, decreased its rutting resistance. Therefore, the mixing and compaction temperatures of SBSMB can be decreased by adding low amounts of WCO without excessive performance loss. Thus, during the construction of asphalt pavements, environmental damage can be reduced by utilizing waste materials and reducing CO2 emissions.
