“…Afterwards, the travel time was noted. Then, with the help of the following equation listed in ASTM C-597 (1) and (2), the velocity (V) and dynamic modulus of elasticity (E d ) were determined and the Poisson's ratio for lightweight concretes was taken (0.28) [17,75].…”

The sustainable development of materials is one of the key targets in the modern era of engineering. These materials are developed by different waste products, following the concept of the circular economy. This study focuses on investigating the properties of concrete using carbon black as a partial replacement of natural fine aggregate at different percentages. Experiments were designed according to the British Standard (BS1881-Part-119) and American Standard (ASTM C-78) by including carbon black in concrete beams to perform as filler material to develop sustainable concrete. In this study, mechanical properties of concrete were targeted by developing beams using different percentages (0%, 25%, 50%, 75%, and 100%) as a replacement of fine aggregates. These beams were tested for flexural strength and, later on, the same beams were cut in the form of cubes, following the equivalent cube test mechanism for the compressive strength test. The waste carbon black lightweight concrete developed in this study was utilized for both structural and non-structural purposes. At 25% and 50% replacement, the strength of lightweight concrete varied from 20–18 MPa, and according to American Concrete Institute (ACI) standards, lightweight concrete at 28 days strength with ≥17 MPa can be used as structural concrete, and the remaining 75% and 100% replacement concrete can be used for non-structural purposes. This study will help in the development of economical eco-friendly sustainable concrete materials.

“…Similarly, expandable polystyrene (EPS) is steam-heated styrene in raw beads, allowing it to expand [22]. It is widely used in many concrete applications, especially in the making of concrete blocks, as well as in geotechnical engineering, because it is light and cool [14,23]. It is a new type of additive that can be used in road construction because of its potential beneficial properties, i.e., adhesive properties and large surface area.…”

The increasing costs of virgin content, decreasing resources, and growing plastic waste have shifted the research momentum towards green and sustainable road pavements. Hence, in recent years, various researchers have worked on the utilization of different types of plastic wastes in asphalt concrete by replacing it with binder content. Under this premise, this study examines the effect of expanded polystyrene beads (EPS) as a replacement to the binder at seven different dosages ranging from 5% to 50%. The bitumen of 60/70 grade was utilized in this study. The fresh properties of polymer-modified bitumen were checked and compared to that of conventional specimens. The mechanical properties of all specimens were investigated in terms of Marshall Stability properties. The results indicated that the adding of PEB improves the stability of modified asphalt concrete. Furthermore, the addition of EPS by substituting bitumen content could be a promising way to reduce the environmental impact of bitumen, and will also help in economic infrastructure development.

“…The ultrasonic pulse technique has become popular all over the world due to its simplicity [15]. A series of researches have been published on this subject [40,41]. The basic principle of ultrasonic pulse velocity is to measure the time necessary for the wave to propagate through the medium, which will depend on several factors such as the nature of the material and the presence of water in the pores, among others.…”

During the development of symmetric asphalt concrete material samples, aggregates play a vital role in the performance of its production. Shape characteristics and aggregates geology are two major factors influencing strength parameters of the asphalt concrete mix. In this study, two different geological sources of aggregates with different shape characterizations have been utilized for the development of the asphalt concrete mix. In addition to that, the stability analysis has been performed under different temperature conditions ranging between 25 and 60 • C. By the application of the destructive technique (DT) and non-destructive technique (NDT), the performance of the asphalt concrete mix has been analyzed and compared based on the geology of aggregates under various temperatures. Furthermore, a statistical model has been developed to analyze the stability and performance of the developed asphalt concrete mix with reference to regional climatic conditions. This study will help in the development of symmetric formation of sustainable asphalt materials.Symmetry 2020, 12, 433 2 of 12 bound and unbound condition come from part of or the whole engineering or building structure [4]. The mechanical performance of an aggregate in asphalt pavement has been studied in previous research and presented an approach to find out its response of an unbound coarse aggregate [5]. Damages to highways mostly takes place on surface roads, one of the main reasons is the weakness of a bond between the bitumen binding and the aggregates. Thus, a bond should be enhanced and to improve the antistripping properties of asphaltic concrete. Stripping is the phenomenon of surface tension between the aggregates and binder. The failure of the asphalt pavement due to several distress such as rutting on the variation of rut depth due to traffic load have been studied using statistical analysis [6]. The several types of distress including creep, rutting, shoving, cracking, and low stability are resulting in stripping due to the ingredient's compatibility. When the ingredients are used in correct proportions, they provide the best-expected service quality [7,8]. The performance of asphalt concrete by using the design method and rehabilitation timing and the result revealed that the road surface was greatly influenced due to traffic load and environmental conditions [9]. The temperature effect is also a key factor that has a direct influence on the viscosity of bitumen, which affects its ability to bond and provide adequate bonding for aggregates in Hot Mix Asphalt (HMA) paving mixes. Therefore, the performance of the asphalt mixture under the effect of increasing and decreasing temperatures is needed to be studied. Low stability in the asphalt mixture leads to various types of distress [10,11]. The maximum load resisting by the specimen before failure is the stability strength of that specimen. An arrangement of the Marshall test [12] is like an indirect tensile strength test [13], but the sample placed in the Marshall test head is within a certa...
