“…Cutback bitumen is made by dissolving bitumen with an appropriate proportion of solvents such as kerosene, furnace oil and diesel oil [33]. The solvent is mixed to reduce bitumen's viscosity and helps it to bind with aggregate after gradual evaporation.…”

The amendment of manufacturing cold mix asphalt (CMA) following proper mix design and strength enhancing techniques serves as an avenue to minimize the enormous volume of carbon footprint and energy consumption resulting from hot mix asphalt. In terms of methodological assumptions, the authors highlighted the mix design components and production procedure for CMA. Acceleration of strength in CMA is related chiefly to mixture curing over time, influenced by different curing regimes to simulated field curing conditions, as highlighted in this study. The additional factor that influences the mechanical strength of CMA is deeply reviewed, which helps the engineers and researchers to improve the existing CMA used in road sectors. The examples of the contents mapped in the review of strength enhancement of CMA are mixture and binder modifiers, fillers and fibers and some other recycling materials and rehabilitation techniques that may influence the sustainability of CMA. The reviewed publications expose scenarios under which different adopted materials and methods can reduce the major distress phenomenon such as fatigue and rutting of CMA. To promote the application of CMA, this manuscript reviewed a deep insight view about the technical aspects associated with CMA.

“…These techniques with lower conforming temperatures have been successfully carried out; however, in most cases they involve sacrificing mechanical properties. Therefore, the higher requirement for quality mixtures in most cases is incompatible with this technique [9].…”

Roads are currently essential links of communication and economic development. However, these roads are progressively requiring higher quality materials, implying a greater impact on the environment, in order to withstand the high levels of heavy vehicle traffic. Therefore, this research proposes the use of industrial by-products to create bituminous mixtures which are more resistant and durable than traditional ones. The industrial by-products used, are electric arc furnace slag, ladle furnace slag, and cellulose fibers from the papermaking industry. These by-products were physically and chemically characterized to be used to conform with bituminous mixtures. At the same time, bituminous mixtures were conformed with conventional materials, thus being able to compare the physical and mechanical properties of the conformed mixtures through different tests. The results showed how the use of cellulose fibers made it possible to absorb a greater percentage of bitumen, as well as the use of electric arc furnace slag and ladle furnace slag created mixtures, with greater Marshall stability. Therefore, sustainable, durable, resistant, and high waste mixtures were developed in this investigation.

“…Road and highway pavement infrastructure are crucial for national economies and societies as they ease transportation and the connections between communities. Road paving materials like asphalt and concrete are prone to deteriorations due to environmental and traffic factors [1]. The most common form of these deteriorations are potholes, which pose risks to vehicles and people [2].…”

“…Although HMA is of a high quality, it is energy-consuming and consequently expensive. On the contrary, CMA has a lower impact on energy consumption and environmental pollution but its mechanical performance is poorer [1,6]. Several properties are taken into consideration when repairing potholes in choosing the patching material, such as workability, cohesion, traffic loading, environmental durability, bonding, freeze-thaw and rutting potential [7].…”

The maintenance of potholes is a long-standing problem. Previous studies focused on pothole patching materials and methods but not on bonding at the interface joint. In this study, the influence of the patching shape and depth on the bonding at the interface joint using two patching materials: hot mix asphalt (HMA) and hot mix asphalt containing 5% (by volume) steel fiber (HMA+) was investigated. Slabs with circular and square potholes in the middle with different depths (35, 50 and 70 mm) were prepared. The two shapes of potholes were patched with two patching materials: HMA and HMA+, at different depths. The slabs were tested after patching using a rigid steel frame. The experimental results were compared with those obtained from finite element analysis using the ABAQUS software, applying the same model of slabs with the same dimensions and properties of the materials used. The results indicated that the bonding at joint interface for circular-patched potholes slightly improved using HMA+ and this was independent of patching depth. As for the square-patched potholes, the bonding at the interface joint was better than for the circular-patched ones; the bonding increased with increasing depth. Using HMA+ for patching the square-patched potholes, the bonding at the interface joint slightly increased, only for the 3.5 cm depth.
