“…In a recent study by Bridgelall et al [56], IRI was determined by using a connected vehicle method, which accounts for all vibration wavelengths experienced by the vehicle. An online recommendation tool for airport pavement maintenance was developed by the Texas Transportation Institute (TTI) to identify optimal cost-effective preservation treatments for flexible pavements [57]. Swei et al [58] studied the importance of changes in the cost of future maintenance, rehabilitation, and reconstruction events and suggested the use of a probabilistic approach.…”

Pavement management is a set of tools used to evaluate and maintain pavements so that the pavements can be used safely and effectively over a certain period. Many traditional methods were and are still being used by entities related to pavement management to increase the efficiency of management in decision-making and in coordinating the different activities that have a direct impact on pavement systems. Most of the pavement management entities are driven by optimization models that allow the optimization of a single objective. There is no specific method that focuses on analyzing and prioritizing multiple pavement perspectives in view of financial goals. This paper aims to provide the pavement management sector with a new methodology that prioritizes various pavement perspectives in view of financial perspectives. This prioritization would lead to a better assessment of multiple pavement management goals. The quality function deployment (QFD) and balanced scorecard (BSC) were adopted and modified to achieve the study objectives. Consequently, the outcome of QFD-BSC analysis is studied in the Fishbone Diagram and Cause-Effect Analysis to graphically present how significant factors in four perspectives will lead to better financial goals in the pavement management industry. Prioritization of pavement goals would help better to allocate optimal resources by pavement management professionals. INDEX TERMS Pavement management, pavement perspectives, pavement condition, pavement management model, balanced score card, quality function deployment.

“…The evaluated of the pavements is done by using the Pavement Condition Index PCI, and the procedure of evaluating is documented in the ASTM D5340 and ASTM D6433 ( Arabali & Borowiec, 2017). There is a scale for PCI that is valued from zero to one hundred (0 to 100).…”

The research aims to discuss and investigate the process of airport pavement management system (APMS). The methodology of the research is based on previous studies that describe the major elements of the APMS to gain more solutions from the previous different case studies. The investigate includes various subjects such as components and cost approach of the APMS. The methodology used in the research is a descriptive method based on previous studies and from different books by using pavement management system (PMS). The study describes the typical distress types of the asphalt-surfaced pavements and the Portland cement concrete pavements of airports. Additionally, the research clarifies the test methods of the airport pavement, such as the ASTM D5340 and ASTM D6433. Research investigates that the software used in the APMS like PAVER and Road-SIT, Airport PMS that are used by the airport agencies to collect information about the situation of the runway pavement. The APMS still needs more research and new studies due to a lack of information and studies in different airports around the world. The airports shall use the service life estimation (SLT) for the pavement in the runways and parking. In recent studies, the method is not used, whereas including a quantitative methodology which demonstrates results to facilitate the clarity of the results to illustrate the advantage of the SLT.

“…Another contributing factor to the stiffness of the binder is the interaction of long hydrocarbon chains of the waxes with the N-Alkane-rich crystallizing material in asphalt mix [ 23 , 24 , 25 ]. The small crystalline structure of the Fischer-Tropsch wax molecules reduces brittleness of the paved asphalt road at low temperatures due to the formation of a lattice structure of microscopic particles in the modified binder.…”

The Role of Additives in Warm Mix Asphalt Technology: An Insight into Their Mechanisms of Improving an Emerging Technology

et al. 2020

The asphalt industry’s incentive to reduce greenhouse gas emissions has increased since the 1990s due to growing concerns on environmental issues such as global warming and carbon footprint. This has stimulated the introduction of Warm Mix Asphalt (WMA) and its technologies which serve the purpose of reducing greenhouse gas emissions by reducing the mixing and compaction temperatures of asphalt mix. WMA gained popularity due to the environmental benefit it offers without compromising the properties, performance and quality of the asphalt mix. WMA is produced at significantly lower temperatures (slightly above 100 °C) and thus results in less energy consumption, fewer emissions, reduced ageing, lower mixing and compaction temperatures, cool weather paving and better workability of the mix. The latter of these benefits is attributed to the incorporation of additives into WMA. These additives can also confer even better performance of WMA in comparison to conventional Hot Mix Asphalt (HMA) methods. Even though there are recommended dosages of several WMA additives, there is no general standardized mixture design procedure and this makes it challenging to characterize the mechanism(s) of action of these additives in the warm mix. The effects of the addition of additives into WMA are known to a reasonable extent but not so much is known about the underlying interactions and phenomena which bring about the mechanism(s) by which these additives confer beneficial features into the warm mix. Additives in a certain way are being used to bridge the gap and minimize or even nullify the effect of the mixing temperature deficit involved in WMA processes while improving the general properties of the mix. This review presents WMA technologies such as wax, chemical additives and foaming processes and the mechanisms by which they function to confer desired characteristics and improve the durability of the mix. Hybrid techniques are also briefly mentioned in this paper in addition to a detailed description of the specific modes of action of popular WMA technologies such as Sasobit, Evotherm and Advera. This paper highlights the environmental and technical advantages of WMA over the conventional HMA methods and also comprehensively analyzes the mechanism(s) of action of additives in conferring desirable characteristics on WMA, which ultimately improves its durability.
