Abstract

Three types of fog seals with polymer modified-emulsified asphalt were prepared to improve the durability of the fog seal and the maintenance quality of asphalt. Based on the skid resistance, water seepage, and wet wheel abrasion, the spraying scheme of the fog seal was determined. The variation of surface drying time under different temperatures and humidity was clarified. The road performance evolution law of fog seal under composite conditions and long-term abrasion was revealed, respectively. The results show that the optimal spraying amount of modified emulsified asphalt for three types of fog seals was 0.6 kg/m². The optimal dosage of fine sand for fog seals with waterborne epoxy/polyurethane modified-emulsified asphalt (WER-WPU-JFC-EA) and waterborne epoxy/polyurethane/styrene-butadiene rubber-modified emulsified asphalt (WER-WPU-SBR-EA) was 0.6 kg/m² and 0.4 kg/m², respectively. Under average temperature and humidity, the traffic open time of the fog seal was 1.0–1.5 h. After the long-term action of thermal-oxygen/freeze-thaw and climate/freeze-thaw, the bonding strength of WER-WPU-JFC-EA and WER-WPU-SBR-EA fog seal was still greater than 0.34 MPa. After 50,000 times of wear, the mass loss of WER-WPU-JFC-EA and WER-WPU-SBR-EA fog seal was below 5.2 %, maintaining good skid resistance and waterproof performance.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
