Experimental Research on Ultra Thin Friction Course Interlayer Bonding Strength

並列摘要


An ultra thin friction course (UTFC) is a good performance preventive maintenance technology. Its many properties that improve performance include improved skid resistance, quieter driving ride, harder wearing surface, and effective waterproofing. The study reported in this paper investigates the relationships between the interlayer shear strength and the interlayer bonder properties, amounts of sprayed emulsion bonding agent, and aggregate gradation of the UTFC-10 bituminous mixture through direct shear testing using an interlayer shearing device. The results indicate that the styrene-butadiene-styrene tri-block polymer (SBS)-modified asphalt emulsion studied is a desirable interlayer binder for use with UTFC treatment. The desirable SBS content of the emulsion should be more than 2.5% by weight, the amount of sprayed emu1sion should be about 0.8 to 1.2L per square meter, and the percent air voids in UTFC bituminous mixture should be limited to 8 to 10%.
