“…At the same time, the spraying amount of WEA also affects the interlaminar bonding performance, so it is necessary to carry out the study on the composition and spraying amount of WEA. At present, when the WEA was used as the interlaminar bonding material in the road engineering field, the content of WER was generally 15-25%, and its spraying amount was 0.6-1.2 kg/m 2 [27,28]. In this study, the content of WER was set at three levels of 15%, 20%, and 25%.…”

“…Finally, the wear resistance of the ultrathin OGFC was evaluated by loading wear test, and interlaminar bonding durability of the ultrathin OGFC was determined. [27,28]. To determine the effect of spreading aggregate on the bonding performance of the bonding layer, the friction course composite structure specimens composed of 3 cm AC-13 asphalt mixture + bonding layer (including spreading aggregate and nonspreading aggregate) + 2 cm small particle size aggregate open-graded asphalt mixture (30 cm × 30 cm) were prepared, and their interlaminar shear strength was tested.…”

“…At the same time, WEA as waterproof bonding material used in cement concrete bridge deck pavement has also carried out some research. Liu et al applied WEA to the waterproof bonding layer of bridge deck pavement, and the research results showed that its shear strength, pull-out strength, and shear fatigue performance were better than high those of viscosity asphalt and SBSmodified asphalt [27,28]. e above studies showed that WEA has good interlaminar bonding and water stability performance.…”

This study aims to optimize the bonding performance between the wearing course and the used pavement or the underlying layer and further improve the service quality and durability of the open-graded friction course with small particle size aggregate (ultrathin OGFC). The ultrathin OGFC including waterborne epoxy resin emulsified asphalt (WEA) bonding layer and open-graded asphalt concrete with 9.5 mm nominal maximum aggregate size gradation was optimized. The construction timing of the open-graded asphalt mixture was determined. The road performance, wear resistance, and interlaminar bonding durability of the ultrathin OGFC were comprehensively evaluated. The results show that, based on the basic properties of the open-graded asphalt mixture, its asphalt aggregate ratio is recommended to be 5.0–5.5%. Based on interlaminar shear strength, it is recommended that the open-graded asphalt mixture is paved immediately after WEA bonding material was sprayed, and the bonding layer does not spread aggregate. The WEA containing 20% waterborne epoxy resin (WER) is recommended as bonding layer for the ultrathin OGFC, and the optimized spraying amount is 1 kg/m2. The ultrathin OGFC has good antisliding, drainage, and wear resistance properties. The interlaminar bonding performance, water stability, and durability of WEA bonding layer are obviously better than those of high viscosity asphalt (HVA) and SBS-modified asphalt. The WEA bonding layer can better resist interlaminar shear failure and improve the service quality and service life of the ultrathin OGFC.

“…Last but not least, it ensures high crosslinking density. [14][15][16] So it is safe enough during storage or transportation which greatly improves its use. However, it should be noted that an epoxy coating only acts as a barrier in metal protection.…”

“…Furthermore, the acid-resistance property of membranes should be enhanced to protect textile from further acid penetration. Pitch is an attractive material which can be widely used for fabricating anticorrosion membranes due to its stable chemical structure [12,13]. Among various kinds of pitches, isotropic pitch with suitable softening point can be used to prepare electrospun fibers [14,15].…”

To develop a series of novel acidproof and breathable fabric, electrospun fluorinated polyurethane/polyurethane and pitch nanofibers were directly deposited on polyester/cotton blended fabric. The layered and interpenetrated structured membranes were built to study the effects of different structures on the acidproof and breathable performances. The acidproof and breathable mechanism of different structured composite fabrics had been evaluated via emission scanning electron microscope, X-ray photoelectron spectroscopy, contact angle, porosity, pore size, comfort and mechanical test, respectively. The results showed that the layered structured composite fabric had advantages in acidproof property, i.e. the acid (H2SO4, 80%) contact angle was 130° due to the low surface energy caused by the high fluorine content (36.96%). Meanwhile, such structured composite fabric provided double protection, which made the acid-resistance pressure to reach a high value of 1050 Pa, while the interpenetrated structured composite fabric showed superior comfort and mechanical properties. Due to the high porosity (88.01%), the water vapor transport rate and air permeability were 7554.14 g/m2·24h and 46.33 mm/s, respectively. Due to the relative slip of fluorinated polyurethane/polyurethane fibers was restricted, the tensile strength and bursting strength of interpenetrated one was 1315 N and 795 N, which were higher than layered one.
