| Abstract: |
| Epoxy asphalt concrete has been one of the mainstream technology of steel deck pavement in China. But little specification about evaluation system for its distress condition has been researched and maintenance was still unsystematic. The section weight coefficient of different distress is proposed by analyzing the applicability of the “Highway Performance Assessment Standards”. Indexes mainly including SDPCI, PDR and PCR are presented to evaluate its distress condition. The evaluation system and maintenance plan decision tree were recommended, which can assist scientific maintenance of epoxy asphalt steel deck pavement. |
| Key words: steel deck pavement epoxy asphalt concrete distress condition evaluation system maintenance plan |

| 环氧沥青钢桥面铺装破损状况评价体系研究 张辉1,2；李英涛3；付新新2；潘友强2 （1. 南京航空航天大学 航空学院，南京 210016； 2. 江苏中路工程技术研究院有限公司，南京211800； 3. 江苏高速公路工程养护技术有限公司，南京，210049）
创新点说明
1）本文选用江苏省内悬索桥和斜拉桥为研究对象，对其病害破损方式进行对比，并对省内几座跨江大桥的铺装层病害与正交异性桥面板结构进行协同分析。
2）本文基于《公路技术状况评定标准》（JTG H20-2007），建立环氧沥青钢桥面铺装病害破损状况的相关评价指标，主要包括SDPCI（钢桥面铺装破损状况）、PDR（脱空率）、PCR（裂缝率）等。 3）建立环氧沥青钢桥面铺装与钢箱梁结构一体化的多维度网格化协同评价体系，横向按照不同车道的左、中、右轮迹带进行划分区间，纵向按照缆索（桥跨）进行划分区间。
4）根据桥面使用性能网格化分区评价结果，并基于充分利用桥面铺装剩余性能的考虑，进行桥面分段养护的方案决策，包括小修保养、预防性养护、大中修等。
