Heat-reflective coatings, used to reduce the asphalt pavement temperature and urban heat island effect, have a good cooling effect; coating development, however, generally focuses on cooling. This study aims to design a heat-reflective coating with both durability and cooling effect by considering the functions of each component, improving the coating bond strength and abrasion resistance, and conducting laboratory tests and test section verification. The coating developed exhibits bond strength and abrasion resistance 20% and 49%, respectively, higher than those of ordinary coatings. The experiments reveal a cooling effect of red coating up to 10.2 °C, a bond strength of up to 1.20 MPa at 25 °C, and an abrasion rate of up to 25% after 60 min; the cooling effect is basically the same as that for traditional heat-reflective coatings, but the bond strength and abrasion resistance significantly improved. In the analysis of the test section, the cooling effect reaches 7.0 °C, the performance of anti-skid decreases little, and the coating is still usable normally after 4 months.

A heat-reflective coating can be used to solve various problems, including rutting and deformation caused by the excessively high asphalt pavement temperatures during summer. However, the durability of the heat-reflective coatings applied to asphalt pavement has not been extensively researched. The colour changes, crack development and attenuation of the cooling performance are studied along with the changes in skid resistance and cooling performance because of wear. Subsequently, the lifespan of the heat-reflective coating is predicted based on the results. This study indicates that the amount of spraying is positively correlated with the cooling performance. After 120 days of aging, a B–A type coating shows no cracks or any decay in performance. When the wear rate is less than 40%, the skid resistance of the coating meets the required specifications and the coating exhibits good cooling performance. The lifespan of the heat-reflective coating is predicted to be one year.

The calculation method of asphalt film thickness was proposed by considering the specific surface area of coarse and fine aggregates [computed tomography (CT) and Blaine test methods] and the wrapping effect of fine particles ($<0.075\mathrm{mm}$ ) on the aggregates to investigate the optimal asphalt dosage of asphalt mixtures. The effect of asphalt film thickness on the pavement performance of asphalt mixtures was studied. The optimal asphalt film thickness determination method for asphalt mixtures is proposed based on the pavement performance. The study shows that the asphalt film thickness of $4.4\mathrm{\mu m}$ has the best high-temperature performance. The higher the asphalt film thickness, the better its low-temperature performance, water stability, and fatigue performance. The optimal asphalt film thickness is selected according to the performance requirements of the asphalt mixture in different structural layers and environmental conditions.

The performance of a skid resistance fog seal is studied to develop a high bond performance road skid resistance fog seal. Accordingly, a fog seal is developed based on the bond strength, permeability, and aging resistance. To develop the skid resistance fog seal herein, the skid resistance particle types and dosages are optimized according to the skid and wear resistance properties. The fog seal performance is then verified. Furthermore, the road performance of the skid resistance fog seal is studied, and the optimal amount of the skid resistance fog seal is proposed. Finally, the influence of the construction process on the skid and wear resistance is investigated. The results show that the self-made skid resistance fog seal has better bond strength, permeability, and aging resistance. The 0.6 kg/m² skid resistance fog seal exhibits the best skid and wear resistance and water penetration performance, while the skid resistance fog seal constructed by the premix process has the best skid and wear resistance properties.
