In recent years,implementing mobility-based performance specifications has been a topic of interest for many state transportation agencies (STAs).However,in 2010 a National Cooperative Highway Research Program (NCHRP) domestic scanning tour of best practices in work zone assessment,data collection,and performance evaluations found that no STA has implemented mobility-based performance specifications for highway construction contracts due mainly to the difficulty in obtaining real-time performance data in work zones throughout the duration of the construction.To determine if this type of specification is feasible for highway construction contracts,multiple methods for gathering information were used,including a literature search,interviews,and an online survey.Overall,the study found that the current technology is capable of continuously collecting mobility data necessary for implementing mobility-based performance specifications in highway construction projects.While this type of specification is found to be feasible to implement,it is important to understand that a large amount of data will be collected and extra personnel are needed to monitor and execute the mobility-based performance specifications.

为了获取轻质混凝土用于实体桥梁结构的相关物理力学性能，积累设计、施工经验，采用900级破碎型煤矸石高强陶粒，制作完成了一片20m高强轻质混凝土(LC50)后张预应力足尺空心板梁，进行了反拱度监测以及相关参数的荷载试验。
钢梁与混凝土梁混合使用是有效提高自锚式悬索桥结构性能的重要措施，其中钢梁与混凝土梁的结合段是自锚式悬索桥的关键部位。该部位不仅结构形式复杂，而且传力机理十分不明确。本文结合蕴藻滨大桥，采用理论分析和试验相结合的方法，对该桥混合梁结合段截面应力分布规律、钢混接触面荷载分配关系等力学性能进行研究。其结论为自锚式悬索桥钢混结合段设计提供参考。
厦漳大桥全长约12.3km,路线经过之处为临近台湾海峡地震区域,并多次跨越地震断层,地震设防烈度7～9度,设计地震动峰值加速度0.15～0.4g。厦漳大桥的场地特点使得该桥梁的减隔震设计成为全线桥梁设计的一个重要的控制性因素。目前,在国内厦漳大桥首次系统化地采用了高墩连续体系桥梁隔震设计,为国内高墩连续体系桥梁的减隔震设计做出了示范效应；而由于厦漳大桥处于海湾地区,周围环境属于海洋性气候,隔震体系
本文介绍了厦漳跨海大桥北汊主桥主墩承台海工大体积混凝土夏季施工过程中温度裂缝控制技术，即在仿真计算的基础上优化混凝土配合比，控制混凝土浇筑温度，改善混凝土施工性能，调整混凝土施工工艺，通循环冷却水对混凝土进行降温，采取表面保温保湿养护措施等。现场温度监测结果表明，主承台混凝土内部温度发展与仿真计算结果较为吻合，内部最高温度和内表温差均在温控标准范围内；混凝土表面未发现可见温度裂缝，达到了预期的温控
