Novel palmitic acid–decanoic acid@Ce–Eu/TiO2 (PA–DA@Ce–Eu/TiO2) microspheres with high photocatalysis–thermal–humidity collaborative performance were prepared via a two‐step method. Ce and Eu were used for codoping to modify the TiO2 hollow microspheres to enhance the photocatalytic properties. Furthermore, a eutectic phase change material (PA–DA) was combined with Ce–Eu/TiO2 hollow microspheres to prepare PA–DA@Ce–Eu/TiO2 microspheres. X‐ray diffraction and UV–VIS spectral analyses proved that Ce–Eu codoping enhanced the photocatalytic properties of the PA–DA@Ce–Eu/TiO2 microspheres under solar light; the degradation rate to gaseous formaldehyde at low concentrations reached 54.98% after 5 h. The pore structure, particle size distribution, microstructure, and thermostability of the PA–DA@Ce–Eu/TiO2 microspheres were determined using N2 adsorption isotherms, laser scattering particle size distribution analysis, scanning electron microscopy, and thermogravimetric analysis, respectively. The results showed that the Ce–Eu/TiO2 microspheres had a typical mesoporous structure, concentrated particle size distribution, and rough surface. The porous structure of the PA–DA@Ce–Eu/TiO2 microspheres was conducive to adsorb/desorb moisture, which was recorded to be 0.0575 g/g at 43.16–75.29% relative humidity. The differential scanning calorimeter analysis showed that the phase transition temperature of the PA–DA@Ce–Eu/TiO2 microspheres was 20–22°C and that the PA–DA@Ce–Eu/TiO2 microspheres were stable at 35°C. After 300 thermal cycles, the heat storage capacity of the PA–DA@Ce–Eu/TiO2 microspheres decreased by only 5%. Thus, we concluded that the PA–DA@Ce–Eu/TiO2 microspheres can purify air and control indoor thermal and humidity environments simultaneously and hence can be used as functional building materials to adjust the indoor environment.

“…54$ billion are spent on maintenance of road pavements in America because of moisture damage. About 82% of American Transportation Agencies recommend the use of adhesion promoters in low-performance job mix formulas [7][8][9]. Zhang has used the Rediset [10] Nano-charcoal and coconut shell ash [11] and, Hamedi and Tahami (2018) has used Zycosoil as adhesion promotor [2].…”

Asphalt mixture that is used for the construction of flexible pavements is mainly composed of two constituents i.e. bitumen and aggregate. Sturdy adhesion among bitumen and aggregate is the sign of durability of asphalt pavements. Adhesion is considered as one of the most important factors for sustainable asphalt pavement. This is the motive why its miles utmost important to deeply understand the phenomenon of adhesion considering the effect of alternate in temperature, moisture conditions. In this study softer binder 80/100 was selected that has less adhesion compared to hard pen grades. Limestone aggregates which is commonly used for the construction of asphalt pavements has also been selected. Two types of modifiers (Zeolite and Paraffin Wax) were selected because of the extensive use in asphalt foaming and the polymer modified asphalt mixtures as temperature reducing agent. To investigate the strength of adhesive bond, Bitumen Bond Strength (BBS) was performed at different temperatures, in dry, and wet conditions. To quantify the effect of modifiers on penetration grade and softening point conventional testing is performed. For performance grading, the PG test was performed using Dynamic Shear Rheometer. The comparisons were developed among pull of tensile strength at dry and after 72hrs water conditioning while preserving the temperature at 25 .To check the effect of temperature BBS is performed at 15 . The results illustrate that 2% zeolite shows best results in terms of adhesion and performance grade while Paraffin wax has less adhesion and poor performance grade.

“…However, pavement distress happens frequently with increasing use of asphalt pavements [4,5] and can even be observed during operation times [6][7][8]. The moisture damage to asphalt pavement is a major problem that negatively affects pavement performance, due to its early appearance, the rapid speed with which damage to the pavement occurs, the enormous effect on comfort and safety during driving, and so on [9][10][11][12]. That is to say, moisture damage can significantly shorten the repair cycles and the lifetime of asphalt highway, accordingly increasing the cost of maintenance and repair [13,14].…”

Studies on control of and preventive measures against asphalt pavement moisture damage have important economic and social significance due to the multiple damage and repair of pavements, the reasons for which include the poor interfacial adhesive ability between acidic aggregates and asphalts. Anti-stripping agent is used in order to improve the poor adhesion, and decomposition temperature is regarded as being important for lots of anti-stripping products, because they always decompose and lose their abilities under the high temperature in the mixing plant before application to the pavement. A novel anti-stripping composite, montmorillonoid/Polyamide (OMMT/PAR), which possesses excellent thermal stability performance and is effective in preventing moisture damage, especially for acidic aggregates, was prepared. Moreover, the modification mechanisms and pavement properties were also investigated with reference to the composites. The results show that OMMT/PAR was prepared successfully, improving the interfacial adhesion between the acidic aggregate and the modified asphalt. Due to the nanostructure of OMMT/PAR, the thermal stability was enhanced dramatically and the interfacial adhesion properties were also improved. Furthermore, asphalts modified with OMMT/PAR and their mixtures showed excellent properties. Finally, the moisture damage process and the mechanisms by which OMMT/PAR improves the interfacial adhesion properties are explained through adhesion mechanism analyses.
