“…While HPMs are mostly preferred for concentrated and large areas, CPMs are mostly preferred for dispersed and small areas. Especially in winter and wet days, CPMs have greater advantages compared to HPMs; some of their advantages are easier material storage and transportation, better adaptability to environment and easier application procedures (Biswas et al, 2016;Biswas et al, 2018;Wang et al, 2022). Conventional CPMs are produced mostly using cutbacks or emulsions as asphalt binders along with aggregates, as well as preferably other materials such as anti-stripping agents to improve their performance (Dah et al, 2022;Jain and Singh, 2021;Yu et al, 2017).…”

“…The CPMs with open aggregate gradation and higher air contents have been reported to have lower stability and durability but higher workability (Liu et al, 2013). CPMs are expected to have some of the performance requirements such as workability, initial stability/strength, moisture susceptibility, in-service durability, interfacial bonding (Wang et al, 2022). Although, some or all of these performance requirements are used to evaluate CPMs, there are no universal test and evaluation methods reported to be used for the performance evaluation of CPMs.…”

“…However, there are very few numbers of studies investigating the use of RAP as part of CPMs (Kwon et al 2017). This might be because that the aged binder in RAP could not be easily activated and blended with unaged binder at low temperatures (Wang et al, 2022).…”

In this study, the usability of 100% RAP as a cold patching material (CPM) was experimentally investigated. As part of this study, first, the RAP material has been characterized to determine its binder content and particle size distribution of the extracted aggregate. Then, three sets of RAP specimens (each set has three specimens) were prepared. These specimens were conditioned at 22°C, 40°C and 45°C for three hours. Then, the specimens were compacted with 75 Marshall hammer blows. The compacted specimens were then tested for their Marshall stability, and flow at 22°C. Air contents of the test specimens were also determined . It was observed that as conditioning temperatures of the compacted test specimens increased, their Marshall stability test results increased but their flow and air content test results mostly decreased. Marshall stability test results of all three sets of specimens were well above the specification limits. Moreover, all test specimens except for only one specimen conditioned at 22°C met the flow and air content criteria. It could be concluded that 100% RAP could be used as a CPM especially above 22°C. If it is needed to be used at around 22°C, it must be ensured that it is well compacted so that its air content is below 8% for a durable and comparably long-lasting cold patching application.

“…Conducting small-sized repairs on aged asphalt concrete on airfields in remote locations can be technically and logistically challenging, particularly if hot-mix asphalt (HMA) is utilized since it requires specialized equipment to produce. Cold patch products used on roadways are typically unable to support the high pass levels of aircraft with high wheel loads and tire pressures, particularly after only a few hours of curing [1,2]. Novel methods for producing small amounts of HMA quickly have been studied [3], including inductive HMA, which still requires specialized equipment, as well as a polymer-modified emulsion mixed with RAP that enables the repair product to be spray injected [4,5].…”

“…These conditions significantly reduce the road surface's adhesion coefficient and skid resistance, leading to decreased vehicle speed, extended travel times, increased fuel consumption, and even traffic accidents [1]. Furthermore, traffic issues caused by icy road conditions are a global concern [2]. Consequently, snow and ice melting have become integral components of winter road maintenance, carrying substantial economic and societal benefits [3].…”

This study addresses the critical issue of traffic safety in winter, particularly focusing on the challenges posed by ice and snow on roads. Traditional methods of snow and ice removal are often labor-intensive, inefficient, and environmentally harmful. The objective is to develop a more effective solution for asphalt pavement deicing. Inspired by the anti-icing coating technology used in high-voltage conductors, this research develops an ice-suppressing material designed to reduce the adhesion between snow, ice, and pavement surfaces. The material’s performance is evaluated in terms of deicing efficiency, durability, adhesive properties, and its impact on pavement performance. Test results demonstrate that the developed ice-suppressing material significantly reduces the adhesion between the ice layer and the pavement, facilitating easier removal. This study concludes that the developed ice-suppressing material significantly enhances deicing efficiency on asphalt pavements. It exhibits strong hydrophobic properties, as evidenced by increased water droplet contact angles on coated surfaces (99.5° to 83.3°) compared to clean glass slides (39.2° to 29°). This hydrophobicity effectively reduces ice adhesion, decreasing tensile and shear strength of the ice layer by 38.2% and 63.6%, respectively. Additionally, the material demonstrates superior ice-melting capabilities in sub-zero temperatures, with coated ice cubes showing a higher mass reduction rate than uncoated ones. Importantly, its slow-release nature ensures sustained deicing performance over multiple cycles, maintaining effectiveness after seven test cycles. This study introduces an innovative ice-suppressing material that not only improves the efficiency and environmental impact of deicing methods but also contributes to enhancing road safety in winter conditions. The material’s novel composition and sustained effectiveness present a significant advancement in the field of winter road maintenance.
