“…Chloride in tidal water is the main contributor to damage on the asphalt pavement [48]. Effect of salt in performance of asphalt binders accelerates the failure when salt percentage is more than 3% [49], increases the asphalt stiffening and decrease the adhesion [50], causes aggregate raveling in coastal areas [51], and water stability of mixture [52]. Sea water immersion has more influence on the value of stability, flow, and Marshall Quotient of asphalt mixture compared to fresh water immersion.…”

One of the causes of flexible pavement damage is being submerged in water with a high acidity, such as seawater. To overcome this condition, a study on the use of buton asphalt (as-buton) was conducted. The advantages of as-buton are that it has higher adhesion and is more resistant to temperature changes. As-buton modification by mixing Lawele as-buton Southeast Sulawesi with oil asphalt pen 60/70. This study focuses on determining the effect of the addition of as-buton to the modified asphalt mixture and the effect of seawater immersion on as-buton mixture based on the Marshall characteristic test. The percentage by weight of as-buton used is 5%, 7.5%, and 10%. The immersion was carried out in freshwater and seawater immersion for up to 24 hours at a temperature of 30°C. The result of this study show that the addition of as-buton increase the value of stability, void in mixture, Marshall quotient (MQ), and void in mineral aggregate, but reduce the flow, void filled with asphalt, and density. The increase of stability and MQ value in seawater-immersion due to the addition of as-buton was higher than that in freshwater. The stability value of the 10% modified as-buton mixture in freshwater-immersion increased by 169.338 kg (14.61%) and in seawater-immersion increased by 1261.669 kg (55.65%). The flow value in freshwater-immersion decreased by 1.9 mm (25.33%) while in seawater-immersion decreased by 1 mm (14.08%). For further research, variations in the addition of as-buton will be carried out to produces a modified asphalt mixture.

“…Therefore, it is necessary to use a pipe that meets the high strength load of the road to prevent the flow of liquid. 50 In the meanwhile, Zhu et al 51 discovered that stress concentrations exist near underground pipelines. The stress concentration can be reduced to some extent by increasing pipe spacing and embedded depth.…”

Summary Reducing the excessive use of fossil fuels and developing new sustainable energy sources are challenges and urgent issues people face today. Pavements are rich in thermal energy when exposed to the sun for long periods of time. Thermoelectric technology allows for the conversion of thermal and electrical energy from the temperature difference that exists between the pavement and the underground. Thermoelectric technology applied to pavements could not only harvest energy to power wireless sensors, LED lights or store it in supercapacitors, but also absorb the temperature of the pavement to reduce damage to the pavement. The review summarized previous pavement thermoelectric energy harvesting systems in the areas of the types, advantages and disadvantages, power generation, and economic benefits. Methods to improve the conversion efficiency of thermoelectric energy harvesting devices are discussed in detail, especially the optimization of the cold end, the external environment, and the structure. Starting from the properties of thermoelectric cementitious composites, the applications and future developments of thermoelectric cementitious composites are presented in more detail. The thermoelectric cementitious composites are grouped into thermoelectric pavement energy harvesting solid systems. Finally, the integrated use of thermoelectric generator and thermoelectric cementitious composites for road energy harvesting is proposed. The article provided directions and references for future research on thermoelectric technology in pavement energy harvesting.

“…While some saline-alkali areas have alkaline precipitation, alkaline precipitation raises the pH of rainwater to 8.5-10 [24]. According to previous research works, a wide range of pH values for water solutions have been studied, for instance, by Yang et al [12], Chen et al [16], and Feng et al [20]. In their study, the investigation on the mechanical deterioration of the asphalt mixtures was conducted through immersion in four different water solutions, namely distilled water, an alkaline solution, a sulfate solution, and an acid solution.…”

“…One of the environmental factors influencing the durability of the asphalt concrete is moisture. Moisture damage occurs primarily when the mixture's adhesion bond strength between the binder and the aggregate deteriorates [12]. The moisture susceptibility test according to ASTM D4867 is performed for a total of 36 specimens [28].…”

This research investigates the effect of corrosion solutions on the mechanical properties of asphalt concrete mixtures. A control asphalt mixture (CM) and five polymer-modified (PM) or filler-modified (FM) mixtures containing waste materials are prepared, namely PM high-density polyethylene plastic (PM-PL), PM crumb rubber (PM-CR), FM Para wood ash (FM-PA), FM palm empty fruit bunch ash (FM-EA), and FM rice husk ash (FM-RA). The experiment is conducted by immersing the mixture specimens in four types of water solutions (i.e., distilled water, alkaline solution, sulfate solution, and acid solution), followed by the splitting tests. Finally, the corrosion resistance factor (fc) is computed to assess the corrosive effect of the corrosion solutions. The results show that the degree of reduction in tensile strength mainly depends on the type of corrosion solutions, type of mixtures, and immersion time. FM-EA provides better resistance under the alkaline and acid solutions, while PM-PL exhibits the greatest fc under the sulfate solution. Among all the mixtures, PM-PL shows the greatest ability in withstanding the corrosion solutions.
