“…Laser surface texturing using nanosecond, picosecond, and femtosecond laser techniques has been previously shown to be effective for the creation of superhydrophobic (SH) surfaces in various kinds of materials [48]. Superhydrophobic surfaces have outstanding water resistance characteristics and are non-wetting, anti-icing, dust/mud self-cleaning, and corrosion resistant [140] due to a contact angle greater than 150 • . The nanosecond laser is the most commonly used technique to create superhydrophobic surfaces because of its efficient and less expensive procedure that can process data significantly faster, turning the surface from hydrophobic to superhydrophobic when exposed to ambient circumstances [141][142][143].…”

Surface texture is regarded as a promising solution for enhancing the tribological features of industrial materials due to its outstanding benefits, such as minimization of the contact area, enhancement of the load bearing capacity, storage of the lubricant, and management of the transition between lubrication regimes. Surface texture can be processed under either liquid or gas conditions. As compared to laser ablation in air, employing liquids or other gases as ablation media provides high accuracy and uniformity by limiting the heat-affected zone (HAZ) and other undesired defects to a large extent, as well as high crater structural features. In addition, the synergistic use of different liquid, solid, and additive lubricants with surface roughness recently demonstrated excellent performance. Therefore, surface texture helps to improve the tribological characteristics of a material. This paper reviews the design methodologies and applications of surface texture, emphasizing the proper selection of the appropriate laser parameters and ambient conditions for the best texture quality and functionality. Recent texture geometric design features to improve the film thickness and the self-lubricating system are presented. The ablation environment is explored using various media. The interaction between the lubricants’ types and surface textures is explored based on the operating conditions. Furthermore, surface texture applications using superhydrophobic surfaces, anti-drag, and vibration and noise friction are discussed. We hope that this review plays an enlightening role in follow-up research on laser surface texture.

“…Consequently, the design of superhydrophobic materials is achieved by creating a rough surface [55]. The benefits brought to the materials by the endowment of this capability are diverse, such as promoting antibacterial, anti-corrosive, anti-freeze, contaminant-free, self-cleaning, and water-resistant functions [46,[56][57][58][59][60].…”

Road pavements are designed to withstand road traffic and weathering actions while ensuring comfortable and safe riding conditions as well as low costs and damage to the environment. When a road pavement has additional abilities or reacts to an external stimulus, it is considered to be smart and multifunctional. Examples of such abilities that have been investigated in asphalt mixtures are photocatalytic, superhydrophobic, self-cleaning, deicing/anti-icing, self-healing, thermochromic, and latent heat thermal energy storage abilities. These abilities are developed using different materials such as nano/microparticles (including semiconductor materials and microcapsules), fibers, phase change materials (PCMs), and dyes, often using dissimilar techniques such as spray coating, volume incorporation, spreading, and asphalt binder modification. Owing to their large surface areas, road pavements are true recipients for large amounts of nano/micromaterials, and consequently, act as important "tools" to stimulate an emerging sector related to the scale of production of materials in the form of nanoparticles. Moreover, smart and multifunctional road pavements can be included in the domain of clean technology (e.g., photocatalytic pavements that promote the environmental depollution of NO x -type gases emitted as vehicle exhaust gases). In this context, they can contribute to materializing the transition to a novel socioeconomic model known as "Green Recovery" that is environmentally friendly, sustainable, and inclusive. This model is a very important path toward economic and employment recovery, a vision to which many countries are strongly committed. Therefore, this work reviews new capabilities imparted to asphalt mixtures and provides recommendations.

“…To keep pavement friction on safe levels is one of the transportation engineering main concerns. The presence of water, ice, and snow over the surface drastically reduces friction contributing to the increase of road accidents [21][22][23]. Thus, it is essential to drain or repel the surface water quickly and remove/avoid ice and snow, which can be performed by promoting the superhydrophobic capability with the application of particles as TiO 2 [24,25] TiO 2 or combined with ZnO [25], SiO 2 [26], PTFE [27], fluorine polymer with nano-CaO [28], magnesium-aluminum layered double hydroxides [29], among others, over asphalt pavements usually by spraying coating [5,25,[27][28][29].…”

Functionalization of Smart Recycled Asphalt Mixtures: A Sustainability Scientific and Pedagogical Approach

The sustainable development of our societies demands strong efforts on scientific and technological research while informing and educating students and the general population. Air pollution and road safety hazards constitute two main public health problems that are insufficiently addressed pedagogically. With this work, we aim to contribute to tackeling the problem by presenting the results of scientific research on the development of photocatalytic, superhydrophobic, and self-cleaning recycled asphalt mixtures to achieve an eco-social friendly and smart material able to mitigate socioenvironmental impacts. The functionalization of asphalt is implemented by spraying particles’ solutions over a conventional AC 10, then evaluated by dye degradation and wettability. Firstly, different particles’ solutions (with nano-TiO2 and/or micro-PTFE under water, ethyl alcohol, and dimethyl ketone) were sprayed to select the best solution (BS), which was composed of TiO2-PTFE (4 g/L each) in ethyl alcohol. Two successive spraying coatings (diluted epoxy resin and BS) were performed over conventional and recycled AC 10 (with reclaimed asphalt pavement and steel slags). Their efficiency decreases with the highest resin amounts. The best results were obtained with 0.25 g resin and BS. For the lowest resin amount, all mixtures achieved superhydrophobicity and performed similarly regarding wettability.
