“…One case study published in the International Journal of Emerging Technologies and Innovative Research described the successful application of CMA for repairing potholes in rural roads in India. The study found that cold mix asphalt was a cost-effective and environmentally friendly solution that could be easily applied using manual labor and minimal equipment [40]. In another case study, cold mix asphalt was used to repair Alaska airport runways.…”

Even with the high advancement of the pavement industry, the use of traditional hot mix asphalt (HMA) for pavement construction and maintenance is associated with high energy consumption, greenhouse gas emissions, and production costs. As a result, researchers and industrial practitioners aspire to use cold mix asphalt (CMA) as an alternative that offers environmental and economic benefits. This paper provides an overview of the advancements and challenges in using CMA for sustainable and cost-effective pavement solutions. The paper reviews portrays, and discloses CMA’s recent benefits, such as reduced energy consumption, lower emissions, and enhanced durability. Additionally, the paper addresses the challenges associated with using CMA, including its limited application areas and potential performance issues. It discusses the strategies being developed to overcome these challenges. Furthermore, the paper concludes with recommendations for the future of research and industry development of CMA to further promotion. Meanwhile, it is finalizing the current sight for using CMA as a sustainable, cost-effective pavement solution.

“…This phenomenon encourages an approximately lower cost of fuel compared to HMA. The use of a recycled mix of CMA or cold in-place recycling (CIR) technology reduces the energy consumption by 57% to 63%, which resulted in cost savings of up to $10,000 to $12,000 (approximately) [14]. CIR techniques observed cost savings of $34,000-$39,000 approximately compared to HMA.…”

“…CIR techniques observed cost savings of $34,000-$39,000 approximately compared to HMA. The overall cost saving is 41% to 47% when considering energy, construction and environmental costs [14]. Table 1 illustrates the comparison between the energy consumption and cost for HMA and CIR mixtures containing bitumen emulsion and foam bitumen for 1.6 lane kilometer (LKM).…”

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.

“…The transportation industry and pavement construction are major contributors to resource depletion and environmental pollution (1). The use of recycled asphalt pavement (RAP) materials has, therefore, become increasingly common in pavement construction as a result of its cost and environmental benefits (2)(3)(4)(5)(6). RAP is defined as deteriorated asphalt pavement removed from a paved surface containing aged asphalt mixture (asphalt binder and aggregates) (7).…”

Rejuvenators are used in the asphalt industry to improve the performance and durability of aged binders and facilitate the use of recycled asphalt materials. The purpose of this study was to evaluate the impact of rejuvenator type and dose on the laboratory performance of asphalt binders. For this study, recycled asphalt pavement (RAP) and extracted RAP binder were obtained from an airfield reconstruction project located in Atlantic City, NJ. One petroleum-based (aromatic extract) and three organic-based (corn oil, tall oil, and modified vegetable oil) rejuvenators were evaluated in this study. Each rejuvenator was used at two different rejuvenator doses (6% and 12% by total RAP binder weight) and was aged at three different levels. Performance grade testing, frequency sweep tests, critical temperature differential (ΔTc ), and Fourier transform infrared spectroscopy (FTIR) tests were conducted. Results showed that the use of rejuvenators lowered the high and low performance grade of extracted RAP binders, in particular organic-based rejuvenators had a greater impact on the performance grade. ΔT c was also improved through the use of rejuvenators. In fact, the extracted RAP binder exceeded the high severity ΔTc threshold (−5°C), whereas the rejuvenated RAP binders improved ΔT c to values greater than the low severity threshold (−2.5°C). Similar findings were observed from the Glover-Rowe parameter as well, in which rejuvenated RAP binders improved the cracking resistance of the extracted RAP binder. When assessing the aging susceptibility, modified vegetable oil and corn oil rejuvenators showed the smallest change in performance between aging levels.
