在过去的一个世纪里，美国州立公路和运输官员协会(AASHTO)指定的活荷载一直在不断发展，以跟上不断变化的车辆交通知识和趋势。最新的负荷是基于加拿大过去的交通数据，可能不代表美国一些司法管辖区的现代或未来交通状况。今天，动态称重(WIM)系统可以为桥梁设计和评估、重量限制执行以及非法超载卡车导致桥梁过早损坏的可能性提供有价值的现场特定交通数据，从而为这一困境提供解决方案。桥梁所有者早就认识到将特定地点或州的卡车荷载纳入其桥梁评估和维护计划的重要性。AASHTO LRFD和LRFR Bridge规范已经演变成信息敏感型规范制定的趋势。在保证的情况下，指定的活荷载可以利用更相关的场地或...
Over the past century, the American Association of State Highway and Transportation Officials (AASHTO)-specified live loads have been evolving to catch up with the ever-changing knowledge and trends of vehicular traffic. The latest loads are based on past Canadian traffic data, and may not represent modern or future traffic conditions in some US jurisdictions. Today, weigh-in-motion (WIM) systems can provide a solution to this dilemma by providing valuable site-specific traffic data for bridge design and evaluation, weight-limit enforcement, and the likelihood of illegally overloaded trucks causing premature bridge deterioration. Bridge owners have long recognized the importance of incorporating site- or state-specific truck loads in their bridge evaluation and preservation programs. The AASHTO LRFD and LRFR Bridge Specifications have evolved to advance the trend toward information-sensitive specification formulation. When warranted, the specified live loads can be enhanced utilizing more relevant site or...
