为对港珠澳大桥珠海人工岛通道（原施工便桥）桥面铺装层进行品质化提升并延长桥面系服役寿命，采用了高韧超薄沥青磨耗层对其进行整体罩面。实施过程中，结合桥梁恒载受限、作业时间紧等特点，在铺装层材料与配比设计、桥面修复材料选择与工艺、水泥桥面与铺装层界面处置技术、施工质量精细化管理与控制等方面进行了系统的试验研究和现场实施方案设计。设计的基于同步摊铺工艺的高韧超薄沥青磨耗层具有实施厚度薄、铺装性能强、压实功需求小、施工效率高等技术特点。经现场测试，罩面前后的桥面铺装在构造深度（提升0.34 mm）、摩擦系数（提升15.5 BPN）、降噪性能（降低噪音3~6 dB）与平整度（由6.5 mm提升至1.4 mm）上得到了明显改善，且其密水性能（<30 mL/min）和拉拔强度（>0.7 MPa）良好。相关的成套技术体系可进一步推广为各类公路、城市道路、桥梁和隧道结构的表面磨耗层方案。

This paper describes a high-toughness, ultra-thin friction course developed to improve the pavement quality and extend the service life of the channel (originally a temporary bridge) for the artificial island in the Hong Kong-Zhuhai-Macao Bridge. The effects of extra loads and the extended operating period on the bridge were investigated experimentally for various binding materials, gradation designs, repair plans for the bridge deck, various bonding interface treatment, and construction quality management techniques. The results show that the high-toughness, ultra-thin friction course coupled with synchronous paving provides thinner pavement thicknesses, much higher mechanical strength, less compaction requirement, and higher construction efficiency. The texture depth (increased by 0.34 mm), friction coefficient (increased by 15.5 BPN), noise (reduced by 3~6 dB), and flatness (improved from 6.5 mm to 1.4 mm) were significantly better than for the original cement concrete bridge pavement. The water sealing ability (< 30 mL/min) and the debonding strength (> 0.7 MPa) reached a good condition. This paving system can also be applied upgrade highway, urban road, bridge, and tunnel surfaces.
