Scope

The interlayer adhesion and functional performance of asphalt pavement structures are key factors determining the overall mechanical performance, durability, and service safety of pavements. Engineering practice shows that insufficient interlayer adhesion, the formation of water damage channels between layers, accumulation of shear fatigue between layers, and the coupling effect of temperature and moisture can significantly accelerate the development of pavement diseases such as rutting, displacement, interlayer slippage, voids, loosening, potholes, and the expansion of reflection cracks. Especially in areas with heavy traffic, long steep slopes in mountainous regions, bridge deck pavement, old road resurfacing, and humid or high temperature environments, traditional "single adhesive layer or penetration layer" oils are difficult to simultaneously meet the comprehensive requirements of adhesion, stress relief, water resistance, shear resistance, and durability. There is an urgent need to achieve multi-objective coordination through the construction of "interlayer functional layers". Interlayer functional layers are typically located between asphalt structural layers or between the base layer and the surface layer. They are formed using spray-type, sprinkle-type, or paving-type materials and processes to create transition layers with specific functions, including enhanced adhesion, waterproofing, anti-shear and anti-slip properties, stress absorption, interface reinforcement, anti-reflection cracking, water damage delay, and improved construction adaptability. However, such structures have high requirements for construction conditions, material systems, interface cleanliness and dryness, spray/sprinkle uniformity, dosage control, temperature windows, traffic organization, and finished product protection. If not properly controlled, issues such as insufficient penetration, adhesion failure, localized excess/insufficient oil, increased slippage risk, and peeling or
