一、前言道路工程由设计→施工→使用→维修→使用→再设计这样的循环中,需要进行各种试验和测定调查。例如在设计阶段需进行CBR试验和各种材料的物理力学性质试验。在施工过程中,需进行施工管理的质量检验。交付使用后,为掌握道路工作状况需定期进行必要的试验和路面耐用性测定。另外道路维修时,评定旧路现有强度以便确定合理的维修方案,也需进行各种路用性能测定
First, the preface Road engineering from design → construction → use → maintenance → use → re-design of such a cycle, the need for a variety of tests and determination of the survey. For example, CBR tests and physical and mechanical properties tests of various materials are required during the design phase. In the construction process, the need for quality inspection of construction management. After delivery, it is necessary to regularly conduct the necessary tests and determination of the durability of the road for grasping the working condition of the road. In addition, the road maintenance, assess the existing strength of the old road in order to determine a reasonable maintenance program, but also for a variety of road performance measurement
